-01 Avr. 2015: Osync v1.00pre
-- Improved and refactored the soft deletion routine by merging conflict backup and soft deletion

-	- Added more logging
-- Merged various fixes from onovy (http://github.com/onovy) Thanks!
-	- Lowered sleep time between commands
-	- Check if master and slave directories are the same
-	- Check script parameters in osync.sh and osync-batch.sh

-++++++ Work comments
-
-Whenever there is some idea to postpone, use #TODO[-version]:[dev-name:] some remark
-A marker must be left where on the line a dev is working (when the work isn't finished). Marker is #WIP:dev-name: some remark
-dev-name is mandatory if more than one person is coding
-Example: #TODO-v2.1:deajan: need to do something
-
-++++++ Variables
-
-All local variables are lowercase, separated by _ (ex: low_wait)
-All global variables full upercase, separated by _ (ex: EXEC_TIME)
-All environment variables (verbose, silent, debug, etc) have prefix _ and are full upercase, separated by _ (ex: _PARANOIA_DEBUG)
-
-++++++ Functions
-
-Every word in a function begins with an uppercase (ex: SomeFunctionDoesThings)
-
-Define functions this way. Use sed ':a;N;$!ba;s/\n{\n/ {\n/g' to adapt when opening bracket is on a new line.
-
-function something {
-	
-}
-
-If function has some arguments, use local variable names that are more readable than $1...$n. Explain via comments what those variables contain if needed.
-
-function anotherthing {
-	local var_name="${1}"
-	local other_var_name="${2}" # This variable contains stuff
-}
-
-Functions should always have return status
-function thirdthing {
-	some_command
-	return $?
-}
-
-++++++ Sub functions
-
-When a function is a subroutine of another function, it is called _SomethingAsSubFunction
-
-++++++ Function argument check
-
-Bash does not provide any checks against missing function arguments. Also, missing quotes can lead to an inconsistent number of arguments.
-Every function call will be checked by __CheckArguments which takes the number of arguments, $# (the real number of args given), the parent function name and the parent function's arguments.
-__CheckArguments will trigger a critical error if number of arguments if incorrect. This will also prevent silent typo errors.
-Ex:
-
-function Something {
-	local some="${1}"
-	local other="${2}"
-	local args="${3}"
-	__CheckArguments 3 $# $FUNCNAME "$*"
-
-__CheckArguments will only trigger if script is called with DEBUG=yes
-Also, with PARANOIA_DEBUG=yes, __CheckArguments will recount all arguments given by "$*" and compare. This can mislead if arguments contain spaces.
-
-++++++ If statements
-
-If statements will be fully written (word "if" must be used). then is written on the same line.
-(Use sed ':a;N;$!ba;s/]\n\t*then/]; then/g' to convert files to this format... Replace "],new line, zero or more tabs, then" by "; then")
-if [ something ]; then
-	stuff
-else
-	other stuff
-fi
-
-++++++ Logging
-
-A logging function is available with the following levels of logging:
-
-- DEBUG: Only log this when DEBUG flas is set in program. Any command forged for eval should be logged by this.
-- NOTICE: Standard messages
-- WARN: Requires attention
-- ERROR: Program produced an error but continues execution
-- CRITICAL: Program execution is halted
-
-++++++ Eval
-
-Most commands should be logged to a tmp file.
-The basic way of doing is:
-
-cmd='"something '$somevar'" > some_file 2>&1'
-eval $cmd &
-WaitForTaskCompletion $! 0 0 $FUNCNAME
-
-Remote commands should exist as:
-
-cmd=$SSH_CMD' "some; commands \"'$VARIABLE'\" some; other; commands" > some_file 2>&1'
-
-++++++ File variables
-
-All eval cmd should exit their content to a file called "$RUNDIR/osync.$FUNCNAME.$SCRIPT_PID"
-Dots are used instead of '_' so variables can be separated with a forbidden char in variables, so they get detected.
-
-++++++ Finding code errors
-
-Use shellcheck.net now and then (ignore SC2086 in our case)
-
-Use a low tech approach to find uneven number of quotes per line
-
-tr -cd "'\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'
-tr -cd "\"\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'
-
-++++++ ofunctions
-
-As obackup and osync share alot of common functions, ofunctions.sh will host all shared code.
-Dev programs n_osync.sh and n_obackup.sh will source ofunctions.sh
-Release programs will still include ofunctions.sh in order to enhance ease of use.
-
-Ofunctions are defined like:
-
-#__FUNC:FunctionName
-function FunctionName {
-
-}
-#__ENDFUNC
-
-These functions are inserted into code that has placeholders like #__FUNC:FuncName

+-   Cannot finish sync if one replica contains a directory and the other replica contains a file named the same way (Unix doesn't allow this)
+-   Daemon mode monitors changes in the whole replica directories, without honoring exclusion lists
+-   Soft deletion does not honor exclusion lists (ie soft deleted files will be cleaned regardless of any exlude pattern because they are in the deleted folder)

+A two way filesync script running on bash Linux, BSD, Android, MacOSX, Cygwin, MSYS2, Win10 bash and virtually any system supporting bash.
+File synchronization is bidirectional, and can be run manually, as scheduled task, or triggered on file changes in monitor mode.
+It is a command line tool rsync wrapper with a lot of additional features baked in.
+
+This is a quickstart guide, you can find the full documentation on the [author's site](http://www.netpower.fr/osync).
 
 ## About
 
-Osync provides the following capabilities
-	
-- Fault tolerance with resume scenarios
-- Email alerts
-- Logging facility
-- Soft deletition and multiple backups handling
-- Before / after command execution
-- Time control
-- Directory monitoring
-- Running on schedule or as daemon
-- Batch runner for multiple sync tasks with rerun option for failed sync tasks
-- ACL synchronization
+osync provides the following capabilities:
 
-osync uses a initiator / target sync schema. It can sync local to local or local to remote directories. By definition, initiator replica is always a local directory on the system osync runs on.
-osync uses pidlocks to prevent multiple concurrent sync processes on/to the same initiator / target replica.
-You may launch concurrent sync processes on the same system but only for different initiator replicas.
-osync tasks may be launched sequentially by osync osync-batch tool.
+-   Local-Local and Local-Remote sync
+-   Fault tolerance with resume scenarios
+-   POSIX ACL and extended attributes synchronization

+-   Before/after run command execution
+-   Email alerts
+-   Logging facility
+-   Directory monitoring
+-   Running on schedule or as daemon
+-   Batch runner for multiple sync tasks with rerun option for failed sync tasks
 
-Currently, it has been tested on CentOS 5.x, 6.x, 7.x, Debian 6, Debian 7, Linux Mint 14-17, Ubuntu 12.04, 12.10, FreeBSD 8.3, 10.1, 10.3, Mac OS X and pfSense.
-Microsoft Windows is supported via MSYS or Cygwin.
+osync is a stateful synchronizer. This means it's agentless and doesn't have to monitor files for changes. Instead, it compares replica file lists between two runs.
+A full run takes about 2 seconds on a local-local replication and about 7 seconds on a local-remote replication.
+Disabling some features file like attributes preservation and disk space checks may speed up execution. 
+osync uses a initiator/target sync schema. It can sync local to local or local to remote directories. By definition, initiator replica is always a local directory on the system osync runs on.
+osync uses pidlocks to prevent multiple concurrent sync processes on/to the same initiator/target replica.
+You may launch concurrent sync processes on the same system but as long as the replicas to synchronize are different.
+Multiple osync tasks may be launched sequentially by osync osync-batch tool.

 ## Installation
 
-Osync has been designed to not delete any data, but rather make backups of conflictual files or soft deletes.
+osync has been designed to not delete any data, but rather make backups of conflictual files or soft deletes.
 Nevertheless, you should always have a neat backup of your data before trying a new sync tool.
 
-You can download the latest stable release of Osync at www.netpower.fr/osync or https://github.com/deajan/osync/archive/v1.1.tar.gz
+Getting osync via GitHub (remove the -b "stable" if you want latest dev snapshot)
 
-You may also get the last development version at https://github.com/deajan/osync with the following command
+	$ git clone -b "stable" https://github.com/deajan/osync
+	$ cd osync
+	$ bash install.sh
 
-	$ git clone -b "v1.1" https://github.com/deajan/osync
-	$ sh install.sh
+Installer script accepts some parameters for automation. Launch install.sh --help for options.
 
-Osync will install itself to /usr/local/bin and an example configuration file will be installed to /etc/osync
+There is also an RPM file that should fit RHEL/CentOS/Fedora and basically any RPM based distro, see the GitHub release.
+Please note that RPM files will install osync to `/usr/bin` instead of `/usr/local/bin` in order to enforce good practices.
 
-Osync needs to run with bash shell. Using any other shell will most probably result in errors.

+
+osync needs to run with bash shell. Using any other shell will most probably result in errors.
 If bash is not your default shell, you may invoke it using
 
 	$ bash osync.sh [options]
 
-On *BSD, be sure to have bash installed.
-On MSYS, On top of your basic install, you need msys-rsync and msys-coreutils-ext packages.
+On *BSD and BusyBox, be sure to have bash installed.
 
-## Upgrade from v1.0x
+If you can't install osync, you may just copy osync.sh where you needed and run it from there.
+
+Arch Linux packages are available at <https://aur.archlinux.org/packages/osync/> (thanks to Shadowigor, <https://github.com/shadowigor>).
+
+## Upgrade from previous configuration files
 
 Since osync v1.1 the config file format has changed in semantics and adds new config options.
 Also, master is now called initiator and slave is now called target.
+osync v1.3 also added multiple new configuration options.
 
-You can upgrade all v1.0x-v1.1-dev config files by running the upgrade script
+You can upgrade all v1.0x-v1.3-dev config files by running the upgrade script
 
-	$ ./upgrade-v1.0x-v1.1x.sh /etc/osync/your-config-file.conf
+	$ ./upgrade-v1.0x-v1.3x.sh /etc/osync/your-config-file.conf
 
 The script will backup your config file, update it's content and try to connect to initiator and target replicas to update the state dir.
 
 ## Usage
 
-Osync can work with in three flavors: Quick sync mode, configuration file mode, and daemon mode.
-While quick sync mode is convenient to do fast syncs between some directories, a configuration file gives much more functionnality.
-Please use double quotes as path delimiters. Do not use escaped characters in path names.
+Osync can work in 3 modes:
+1. [:rocket: Quick sync mode](#quick-sync-mode)
+2. [:gear: Configuration file mode](#configuration-file-mode)
+3. [:mag_right: Monitor mode](#monitor-mode)
+
+> [!NOTE]
+> Please use double quotes as path delimiters. Do not use escaped characters in path names.
+
+### <a id="quick-sync-mode"></a>:rocket: Quick sync mode
+
+Quick sync mode is convenient to do fast syncs between some directories. However, the [configuration file mode](#configuration-file-mode) gives much more functionality.
 
-QuickSync example
------------------
 	# osync.sh --initiator="/path/to/dir1" --target="/path/to/remote dir2"
 	# osync.sh --initiator="/path/to/another dir" --target="ssh://user@host.com:22//path/to/dir2" --rsakey=/home/user/.ssh/id_rsa_private_key_example.com
 
-Running osync with a Configuration file
----------------------------------------
-You'll have to customize the sync.conf file according to your needs.
-If you intend to sync a remote directory, osync will need a pair of private / public RSA keys to perform remote SSH connections.
-Also, running sync as superuser requires to configure /etc/sudoers file.
-Please read the documentation about remote sync setups.
-Once you've customized a sync.conf file, you may run osync with the following test run:
+#### Quick sync with minimal options
+
+In order to run osync the quickest (without transferring file attributes, without softdeletion, without prior space checks and without remote connectivity checks, you may use the following:
+
+	# MINIMUM_SPACE=0 PRESERVE_ACL=no PRESERVE_XATTR=no SOFT_DELETE_DAYS=0 CONFLICT_BACKUP_DAYS=0 REMOTE_HOST_PING=no osync.sh --initiator="/path/to/another dir" --target="ssh://user@host.com:22//path/to/dir2" --rsakey=/home/user/.ssh/id_rsa_private_key_example.com
+
+All the settings described here may also be configured in the conf file.
+
+### Summary mode
+
+osync will output only file changes and errors with the following:
+
+	# osync.sh --initiator="/path/to/dir1" --target="/path/to/dir" --summary --errors-only --no-prefix
+
+This also works in configuration file mode.
+
+### <a id="configuration-file-mode"></a>:gear: Configuration file mode
+
+You'll have to customize the `sync.conf` file according to your needs.
+
+If you intend to sync a remote directory, osync will need a pair of private/public RSA keys to perform remote SSH connections. Also, running sync as superuser requires to configure the `/etc/sudoers` file.
+
+> [!TIP]
+> Read the [example configuration file](https://github.com/deajan/osync/blob/master/sync.conf.example) for documentation about remote sync setups.
+
+Once you've customized a `sync.conf` file, you may run osync with the following test run:
 
 	# osync.sh /path/to/your.conf --dry
 
-If everything went well, you may run the actual configuration with one of the following:
+If everything went well, you may run the actual configuration with:
 
 	# osync.sh /path/to/your.conf

+To display which files and attrs are actually synchronized and which files are to be soft deleted / are in conflict, use `--verbose` (you may mix it with `--silent` to output verbose input only in the log files):
+ 
 	# osync.sh /path/to/your.conf --verbose
-	# osync.sh /path/to/your.conf --no-maxtime
 
-Verbose option will display which files and attrs are actually synchronized and which files are to be soft deleted / are in conflict.
-You may mix "--silent" and "--verbose" parameters to output verbose input only in the log files.
-No-Maxtime option will disable execution time checks, which is usefull for big initial sync tasks that might take long time. Next runs should then only propagate changes and take much less time.
+Use `--no-maxtime` to disable execution time checks, which is usefull for big initial sync tasks that might take long time. Next runs should then only propagate changes and take much less time:
+ 
+ 	# osync.sh /path/to/your.conf --no-maxtime

-Daemon mode
------------
-Additionnaly, you may run osync in monitor mode, which means it will perform a sync upon file operations on initiator replica.
-This can be a drawback on functionnality versus scheduled mode because this mode only launches a sync task if there are file modifications on the initiator replica, without being able to monitor the target replica.
-Target replica changes are only synced when initiator replica changes occur, or when a given amount of time (default 600 seconds) passed without any changes on initiator replica.
-File monitor mode can also be launched as a daemon with an init script. Please read the documentation for more info.
-Note that monitoring changes requires inotifywait command (inotify-tools package for most Linux distributions).
-BSD, MacOS X and Windows are not yet supported for this operation mode, unless you find a inotify-tools package on these OSes.

+
+## Contributions
+
+All kind of contribs are welcome.
+
+When submitting a PR, please be sure to modify files in dev directory (`dev/n_osync.sh`, `dev/ofunctions.sh`, `dev/common_install.sh etc`) as most of the main files are generated via merge.sh.
+When testing your contribs, generate files via merge.sh or use bootstrap.sh which generates a temporary version of n_osync.sh with all includes.
+
+Unit tests are run by travis on every PR, but you may also run them manually which adds some tests that travis can't do, via `dev/tests/run_tests.sh`.
+SSH port can be changed on the fly via environment variable SSH_PORT, e.g.:
+
+	# SSH_PORT=2222 dev/tests/run_tests.sh
+
+Consider reading CODING_CONVENTIONS.TXT before submitting a patch.
+
+## Troubleshooting
+
+You may find osync's logs in `/var/log/osync.[INSTANCE_ID].log` (or current directory if `/var/log` is not writable).
 Additionnaly, you can use the --verbose flag see to what actions are going on.
 
+When opening an issue, please post the corresponding log files. Also, you may run osync with _DEBUG option in order to have more precise logs, e.g.:
+
+	# _DEBUG=yes ./osync.sh /path/to/conf
+
+## Uninstalling
+
+The installer script also has an uninstall mode that will keep configuration files. Use it with
+
+	$ ./install.sh --remove

+Coding style used for my bash projects (v3.2 Oct 2018)
+As bash is clearly an error prone script language, we'll use as much standard coding as possible, including some quick and dirty debug techniques described here.
+
+++++++ Header
+
+Always use the following header
+
+----BEGIN HEADER
+#!/usr/bin/env bash
+
+PROGRAM="program-name" # Long description
+AUTHOR="(C) 20XX-20YY by Orsiris de Jong"
+CONTACT="http://www.example.com me@example.com"

+Using bind style versionning:
+YYYYMMDDVV (Year, Month, Day, Revision): Example: 2015012402 = 2nd revision of 24 Jan 2015
+
+#!/usr/bin/env bash instead of #!/bin/bash
+
+Change old scripts with
+for i in $(grep -r '#!/bin/bash' * |cut -f1 -d':'); do sed -i 's&#!/bin/bash&#!/usr/bin/env bash&g' $i; done
+
+type instead of type -p for bash test (other shells don't know -p)
+
+++++++ Indentation
+
+Using tabs
+Transform old shell scripts using unexpand command
+
+++++++ Comments
+
+Some command # comment
+## Some comment on a new line
+################################################# Some separation
+
+++++++ Work comments
+
+Whenever there is some idea to postpone, use #TODO(priority):[dev-name:] some remark
+Priority can be critical, high, medium, low, verylow. No release can happen if there are TODOs other than low or verylow.
+Example: #TODO(high):deajan: need to do something
+
+A "work in progress" marker must be left on the line a dev is working when it's work isn't finished). Marker is #WIP:dev-name: some remark
+dev-name is mandatory if more than one person is coding
+Example: #WIP:deajan: missing function something
+
+++++++ Variables
+
+All local variables names have each first letter of the words uppercase and all others lowercase, except for the first word where all letters are lowercase
+Example: someLongVariable
+All global variables are full upercase, separated by _
+Example: EXEC_TIME
+All environment variables (verbose, silent, debug, etc) have prefix _ and are full upercase, separated by _
+Example: _PARANOIA_DEBUG
+
+Exec time variables that can take boolean values should use true and false instead of 1 and 0.
+
+++++++ Functions
+
+All function names should begin with an uppercase letter for every word, the other letters should be lowercase
+Example: SomeFunctionThatRocks
+
+Bash does not provide any checks against missing function arguments. Also, missing quotes can lead to an inconsistent number of arguments.
+Most functions should have a first line that calls the special function __CheckArguments, which checks the number of given arguments for a function in order
+to find possible problems. Number of arguments are given as first argument to __CheckArguments. May be a number or a range, eg 0-2 if the function takes optional arguments.
+__CheckArguments will only trigger when the script is launched with _PARANOIA_DEBUG=yes. Also, it will only exist in the debug version.
+Use the following convention for function definition:
+
+function SomeFunction {
+	__CheckArguments 0 $# "$@"               #__WITH_PARANOIA_DEBUG
+	...	
+}
+
+Use sed ':a;N;$!ba;s/\n{\n/ {\n/g' to convert functions that have opening brackets on a new line.
+
+If the function has arguments, use local variable names that are more readable than $1...$n. Explain via comments what those variables contain if needed.
+Declare arguments before launching __CheckArguments:
+
+function AnotherFunction {
+	local varName="${1}"
+	local otherVarName="${2}" # This variable contains stuff
+	__CheckArguments 2 $# "$@"		#__WITH_PARANOIA_DEBUG
+	...
+}
+
+Functions should always have return status
+function RandomFunction {
+	...
+	return $?
+}
+
+++++++ Sub functions
+
+When a function is a subroutine of another function, it is called _SomethingAsSubFunction:
+Example:
+
+function _ApplyLocally
+function _ApplyRemotely
+function Apply
+
+++++++ For and While statements
+
+For and while statements will have the "do" part on the first line.
+Example:
+
+for i in "${var[@]}"; do
+	...
+done
+
+while [ $i -eq 1 ]; do
+	...
+done
+
+++++++ If statements
+
+If statements will be fully written (word "if" must be used). then is written on the same line.
+(Use sed ':a;N;$!ba;s/]\n\t*then/]; then/g' to convert files to this format... Replace "],new line, zero or more tabs, then" by "; then")
+if [ something ]; then
+	stuff
+else
+	other stuff
+fi
+
+++++++ Logging
+
+A logging function is available that writes both to log file and stdout/stderr.
+It has the following global variable modifiers:
+
+_LOGGER_SILENT=true/false: disables any output to stdout/stderr
+_LOGGER_VERBOSE=true/false: logs messages with log level VERBOSE
+_LOGGER_ERR_ONLY=true/false: disables logging to log file and stdout/stderr except for CRITICAL, ERROR, WARN and ALWAYS log levels. 
+
+The following log levels exist:
+
+- PARANOIA_DEBUG: Only used by debugging functions themselves
+- DEBUG: Only log this when _DEBUG flag is set in program. Any command forged for eval instruction should be logged by this.
+- NOTICE: Standard messages
+- ALWAYS: Standard messages, regardless of _LOGGER_ERR_ONLY
+- WARN: Requires attention
+- ERROR: Program produced an error but continues execution
+- CRITICAL: Program execution is halted
+
+Can be called with:
+Logger "My message" "LOGLEVEL" $retval
+
+$retval is an optional parameter that passes the exit code of the command that triggered the logging message
+$retval, along with function stack, script pid and current pid can be found in the ERROR /WARN alert files ($RUN_DIR/$PROGRAM.Logger.error.$SCRIPT_PID)
+
+++++++ Eval
+
+Most commands should be logged to a tmp file.
+The basic way of doing is:
+
+cmd='"something '$somevar'" > some_file 2>&1'
+eval $cmd &
+WaitForTaskCompletion $! 0 0 1 0 true false true false
+retval=$?
+if [ $retval -ne 0 ]; then
+	Logger "Some error message" "ERROR" $retval
+fi
+
+++++++ includes
+
+Using merge.sh, the program may have includes like
+include #### RemoteLogger SUBSET ####
+All possible includes are listed in ofunctions.sh
+Mostly, includes are needed to port functions to a remote shell without writing them again.
+
+++++++ Remote execution
+
+Remote commands should always invoke bash (using '"'"' to escape single quotes of 'bash -c "command"'). It is preferable to use ssh heredoc in order to use plain code.
+If local and remote code is identical, wrap remote code in a function so only minor modifications are needed.
+Remote code return code is transmitted via exit.
+
+cmd=$SSH_CMD' '"'"'bash -c "some; commands \"'$VARIABLE'\" some; other; commands" > some_file'"'"' 2>&1'
+
+Better formule
+
+$SSH_CMD remoteVar="'$localVar'" 'bash -s' << 'ENDSSH' > 2>&1
+function remoteSub {
+	some code
+	return 0
+}
+
+remoteSub
+exit $?
+ENDSSH
+retval=$?
+if [ $retval -ne 0 ]; then
+	Logger "Some error message" "ERROR" $retval
+fi
+
+We also need to transmit a couple of environment variables (RUN_DIR; PROGRAM; _LOGGER_VERBOSE... see current setups) in order to make standard code.
+Include works here too.
+
+++++++ File variables
+
+All eval cmd should exit their content to a file called "$RUNDIR/$PROGRAM.${FUNCNAME[0]}.$SCRIPT_PID"
+Dots are used instead of '_' so variables can be separated with a forbidden char in variable names, so the separtors apply as wished.
+
+
+++++++ String function calls
+
+String returning functions should only be called this way in order to deal with spaces:
+Quoting happens outside the function call.
+
+echo "$(myStringFunction $myStringVar)"
+
+++++++ ofunctions
+
+As obackup and osync share alot of common functions, ofunctions.sh will host all shared code.
+Dev programs n_osync.sh and n_obackup.sh will source ofunctions.sh
+Release programs will still include ofunctions.sh in order to enhance ease of use.
+
+Ofunctions are defined like:
+
+#__FUNC:FunctionName
+function FunctionName {
+
+}
+#__ENDFUNC
+
+These functions are inserted into code that has placeholders like #__FUNC:FuncName
+
++++++++ includes
+
+ofunctions parts can be directly included in shell scripts.
+The parts that needs to be included must be contained within specific comments:
+
+#### MyFunction SUBSET ####
+function MyFunction {
+	...
+}
+#### MyFunction SUBSET END ####
+
+These can later be included in shell scripts with:
+
+
+include #### MyFunction SUBSET ####
+
+In order to have those includes parsed, we use bootstrap.sh to launch the original shell script.
+Original shell script will not work because include is not a bash statement.
+Include the following code into original shell script
+
+include #### _OFUNCTIONS_BOOTSTRAP SUBSET ####
+[ "$_OFUNCTIONS_BOOTSTRAP" != true ] && echo "Please use bootstrap.sh to load this dev version of $(basename $0)" && exit 1
++++++++ Exit codes
+
+Normal exit code = 0
+Run with errors exit code = 1
+Run with warnings exit code = 2
+Wrong shell exit code = 127
+Usage function exit code = 128
+
++++++++ Detailled debugging
+
+When launching the program with 'bash -x', add SLEEP_TIME=1 so wait functions won't spam output
+Ex:
+
+SLEEP_TIME=1 bash -x ./program.sh
+
+++++++ Finding code errors
+
+Before every release, shellcheck must be run
+Also a grep -Eri "TODO|WIP" osync/* must be run in order to find potential release blockers
+
+Use shellcheck.net now and then (ignore SC2086 in our case)
+
+Use a low tech approach to find uneven number of quotes per line
+
+tr -cd "'\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'
+tr -cd "\"\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'

+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at kate.ward@forestent.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+Coding Standards
+================
+
+shFlags is more than just a simple 20 line shell script. It is a pretty
+significant library of shell code that at first glance is not that easy to
+understand. To improve code readability and usability, some guidelines have been
+set down to make the code more understandable for anyone who wants to read or
+modify it.
+
+Function declaration
+--------------------
+
+Declare functions using the following form:
+
+```sh
+doSomething() {
+  echo 'done!'
+}
+```
+
+One-line functions are allowed if they can fit within the 80 char line limit.
+
+```sh
+doSomething() { echo 'done!'; }
+```
+
+Function documentation
+----------------------
+
+Each function should be preceded by a header that provides the following:
+
+1. A one-sentence summary of what the function does.
+
+1. (optional) A longer description of what the function does, and perhaps some
+   special information that helps convey its usage better.
+
+1. Args: a one-line summary of each argument of the form:
+
+   `name: type: description`
+
+1. Output: a one-line summary of the output provided. Only output to STDOUT
+   must be documented, unless the output to STDERR is of significance (i.e. not
+   just an error message). The output should be of the form:
+
+   `type: description`
+
+1. Returns: a one-line summary of the value returned. Returns in shell are
+   always integers, but if the output is a true/false for success (i.e. a
+   boolean), it should be noted. The output should be of the form:
+
+   `type: description`
+
+Here is a sample header:
+
+```
+# Return valid getopt options using currently defined list of long options.
+#
+# This function builds a proper getopt option string for short (and long)
+# options, using the current list of long options for reference.
+#
+# Args:
+#   _flags_optStr: integer: option string type (__FLAGS_OPTSTR_*)
+# Output:
+#   string: generated option string for getopt
+# Returns:
+#   boolean: success of operation (always returns True)
+```
+
+Variable and function names
+---------------------------
+
+All shFlags specific constants, variables, and functions will be prefixed
+appropriately with 'flags'. This is to distinguish usage in the shFlags code
+from users own scripts so that the shell name space remains predictable to
+users. The exceptions here are the standard `assertEquals`, etc. functions.
+
+All non built-in constants and variables will be surrounded with squiggle
+brackets, e.g. `${flags_someVariable}` to improve code readability.
+
+Due to some shells not supporting local variables in functions, care in the
+naming and use of variables, both public and private, is very important.
+Accidental overriding of the variables can occur easily if care is not taken as
+all variables are technically global variables in some shells.
+
+Type | Sample
+---- | ------
+global public constant           | `FLAGS_TRUE`
+global private constant          | `__FLAGS_SHELL_FLAGS`
+global public variable           | `flags_variable`
+global private variable          | `__flags_variable`
+global macro                     | `_FLAGS_SOME_MACRO_`
+public function                  | `flags_function`
+public function, local variable  | ``flags_variable_`
+private function                 | `_flags_function`
+private function, local variable | `_flags_variable_`
+
+Where it makes sense to improve readability, variables can have the first
+letter of the second and later words capitalized. For example, the local
+variable name for the help string length is `flags_helpStrLen_`.
+
+There are three special-case global public variables used. They are used due to
+overcome the limitations of shell scoping or to prevent forking. The three
+variables are:
+
+- `flags_error`
+- `flags_output`
+- `flags_return`
+
+Local variable cleanup
+----------------------
+
+As many shells do not support local variables, no support for cleanup of
+variables is present either. As such, all variables local to a function must be
+cleared up with the `unset` built-in command at the end of each function.
+
+Indentation
+-----------
+
+Code block indentation is two (2) spaces, and tabs may not be used.
+
+```sh
+if [ -z 'some string' ]; then
+  someFunction
+fi
+```
+
+Lines of code should be no longer than 80 characters unless absolutely
+necessary. When lines are wrapped using the backslash character '\', subsequent
+lines should be indented with four (4) spaces so as to differentiate from the
+standard spacing of two characters, and tabs may not be used.
+
+```sh
+for x in some set of very long set of arguments that make for a very long \
+    that extends much too long for one line
+do
+  echo ${x}
+done
+```
+
+When a conditional expression is written using the built-in [ command, and that
+line must be wrapped, place the control || or && operators on the same line as
+the expression where possible, with the list to be executed on its own line.
+
+```sh
+[ -n 'some really long expression' -a -n 'some other long expr' ] && \
+    echo 'that was actually true!'
+```

+## <a name="introduction"></a> Introduction
+
+shUnit2 was originally developed to provide a consistent testing solution for
+[log4sh][log4sh], a shell based logging framework similar to
+[log4j](http://logging.apache.org). During the development of that product, a
+repeated problem of having things work just fine under one shell (`/bin/bash` on
+Linux to be specific), and then not working under another shell (`/bin/sh` on
+Solaris) kept coming up. Although several simple tests were run, they were not
+adequate and did not catch some corner cases. The decision was finally made to
+write a proper unit test framework after multiple brown-bag releases were made.
+_Research was done to look for an existing product that met the testing
+requirements, but no adequate product was found._

+

+
+## <a name="quickstart"></a> Quickstart
+
+This section will give a very quick start to running unit tests with shUnit2.
+More information is located in later sections.
+
+Here is a quick sample script to show how easy it is to write a unit test in
+shell. _Note: the script as it stands expects that you are running it from the
+"examples" directory._
+
+```sh
+#! /bin/sh
+# file: examples/equality_test.sh
+
+testEquality() {
+  assertEquals 1 1
+}
+
+# Load shUnit2.
+. ../shunit2
+```
+
+Running the unit test should give results similar to the following.
+
+```console
+$ cd examples
+$ ./equality_test.sh
+testEquality
+
+Ran 1 test.
+
+OK
+```
+
+W00t! You've just run your first successful unit test. So, what just happened?
+Quite a bit really, and it all happened simply by sourcing the `shunit2`
+library. The basic functionality for the script above goes like this:
+
+* When shUnit2 is sourced, it will walk through any functions defined whose name
+  starts with the string `test`, and add those to an internal list of tests to
+  execute. Once a list of test functions to be run has been determined, shunit2
+  will go to work.
+* Before any tests are executed, shUnit2 again looks for a function, this time
+  one named `oneTimeSetUp()`. If it exists, it will be run. This function is
+  normally used to setup the environment for all tests to be run. Things like
+  creating directories for output or setting environment variables are good to
+  place here. Just so you know, you can also declare a corresponding function
+  named `oneTimeTearDown()` function that does the same thing, but once all the
+  tests have been completed. It is good for removing temporary directories, etc.
+* shUnit2 is now ready to run tests. Before doing so though, it again looks for
+  another function that might be declared, one named `setUp()`. If the function
+  exists, it will be run before each test. It is good for resetting the
+  environment so that each test starts with a clean slate. **At this stage, the
+  first test is finally run.** The success of the test is recorded for a report
+  that will be generated later. After the test is run, shUnit2 looks for a final
+  function that might be declared, one named `tearDown()`. If it exists, it will
+  be run after each test. It is a good place for cleaning up after each test,
+  maybe doing things like removing files that were created, or removing
+  directories. This set of steps, `setUp() > test() > tearDown()`, is repeated
+  for all of the available tests.
+* Once all the work is done, shUnit2 will generate the nice report you saw
+  above. A summary of all the successes and failures will be given so that you
+  know how well your code is doing.
+
+We should now try adding a test that fails. Change your unit test to look like
+this.
+
+```sh
+#! /bin/sh
+# file: examples/party_test.sh
+
+testEquality() {
+  assertEquals 1 1
+}
+
+testPartyLikeItIs1999() {
+  year=`date '+%Y'`
+  assertEquals "It's not 1999 :-(" '1999' "${year}"
+}
+
+# Load shUnit2.
+. ../shunit2
+```
+
+So, what did you get? I guess it told you that this isn't 1999. Bummer, eh?
+Hopefully, you noticed a couple of things that were different about the second
+test. First, we added an optional message that the user will see if the assert
+fails. Second, we did comparisons of strings instead of integers as in the first
+test. It doesn't matter whether you are testing for equality of strings or
+integers. Both work equally well with shUnit2.
+
+Hopefully, this is enough to get you started with unit testing. If you want a
+ton more examples, take a look at the tests provided with [log4sh][log4sh] or
+[shFlags][shflags]. Both provide excellent examples of more advanced usage.
+shUnit2 was after all written to meet the unit testing need that
+[log4sh][log4sh] had.
+
+If you are using distribution packaged shUnit2 which is accessible from
+`/usr/bin/shunit2` such as Debian, you can load shUnit2 without specifying its
+path.  So the last 2 lines in the above can be replaced by:
+
+```sh
+# Load shUnit2.
+. shunit2
+```
+

+
+## <a name="function-reference"></a> Function Reference
+
+### <a name="general-info"></a> General Info
+
+Any string values passed should be properly quoted -- they should be
+surrounded by single-quote (`'`) or double-quote (`"`) characters -- so that the
+shell will properly parse them.
+
+### <a name="asserts"></a> Asserts
+
+    assertEquals [message] expected actual
+
+Asserts that _expected_ and _actual_ are equal to one another. The _expected_
+and _actual_ values can be either strings or integer values as both will be
+treated as strings. The _message_ is optional, and must be quoted.
+
+    assertNotEquals [message] unexpected actual
+
+Asserts that _unexpected_ and _actual_ are not equal to one another. The
+_unexpected_ and _actual_ values can be either strings or integer values as both
+will be treated as strings. The _message_ is optional, and must be quoted.
+
+    assertSame [message] expected actual
+
+This function is functionally equivalent to `assertEquals`.
+
+    assertNotSame [message] unexpected actual
+
+This function is functionally equivalent to `assertNotEquals`.
+
+    assertContains [message] container content
+
+Asserts that _container_ contains _content_. The _container_ and _content_
+values can be either strings or integer values as both will be treated as
+strings. The _message_ is optional, and must be quoted.
+
+    assertNotContains [message] container content
+
+Asserts that _container_ does not contain _content_. The _container_ and
+_content_ values can be either strings or integer values as both will be treated
+as strings. The _message_ is optional, and must be quoted.
+
+    assertNull [message] value
+
+Asserts that _value_ is _null_, or in shell terms, a zero-length string. The
+_value_ must be a string as an integer value does not translate into a zero-
+length string. The _message_ is optional, and must be quoted.
+
+    assertNotNull [message] value
+
+Asserts that _value_ is _not null_, or in shell terms, a non-empty string. The
+_value_ may be a string or an integer as the latter will be parsed as a non-empty
+string value. The _message_ is optional, and must be quoted.
+
+    assertTrue [message] condition
+
+Asserts that a given shell test _condition_ is _true_. The condition can be as
+simple as a shell _true_ value (the value `0` -- equivalent to
+`${SHUNIT_TRUE}`), or a more sophisticated shell conditional expression. The
+_message_ is optional, and must be quoted.
+
+A sophisticated shell conditional expression is equivalent to what the __if__ or
+__while__ shell built-ins would use (more specifically, what the __test__
+command would use). Testing for example whether some value is greater than
+another value can be done this way.
+
+    assertTrue "[ 34 -gt 23 ]"
+
+Testing for the ability to read a file can also be done. This particular test
+will fail.
+
+    assertTrue 'test failed' "[ -r /some/non-existant/file ]"
+
+As the expressions are standard shell __test__ expressions, it is possible to
+string multiple expressions together with `-a` and `-o` in the standard fashion.
+This test will succeed as the entire expression evaluates to _true_.
+
+    assertTrue 'test failed' '[ 1 -eq 1 -a 2 -eq 2 ]'
+
+<i>One word of warning: be very careful with your quoting as shell is not the
+most forgiving of bad quoting, and things will fail in strange ways.</i>
+
+    assertFalse [message] condition
+
+Asserts that a given shell test _condition_ is _false_. The condition can be as
+simple as a shell _false_ value (the value `1` -- equivalent to
+`${SHUNIT_FALSE}`), or a more sophisticated shell conditional expression. The
+_message_ is optional, and must be quoted.
+
+_For examples of more sophisticated expressions, see `assertTrue`._
+
+### <a name="failures"></a> Failures
+
+Just to clarify, failures __do not__ test the various arguments against one
+another. Failures simply fail, optionally with a message, and that is all they
+do. If you need to test arguments against one another, use asserts.
+
+If all failures do is fail, why might one use them? There are times when you may
+have some very complicated logic that you need to test, and the simple asserts
+provided are simply not adequate. You can do your own validation of the code,
+use an `assertTrue ${SHUNIT_TRUE}` if your own tests succeeded, and use a
+failure to record a failure.
+
+    fail [message]
+
+Fails the test immediately. The _message_ is optional, and must be quoted.
+
+    failNotEquals [message] unexpected actual
+
+Fails the test immediately, reporting that the _unexpected_ and _actual_ values
+are not equal to one another. The _message_ is optional, and must be quoted.
+
+_Note: no actual comparison of unexpected and actual is done._
+
+    failSame [message] expected actual
+
+Fails the test immediately, reporting that the _expected_ and _actual_ values
+are the same. The _message_ is optional, and must be quoted.
+
+_Note: no actual comparison of expected and actual is done._
+
+    failNotSame [message] expected actual
+
+Fails the test immediately, reporting that the _expected_ and _actual_ values
+are not the same. The _message_ is optional, and must be quoted.
+
+_Note: no actual comparison of expected and actual is done._
+
+    failFound [message] content
+
+Fails the test immediately, reporting that the _content_ was found. The
+_message_ is optional, and must be quoted.
+
+_Note: no actual search of content is done._
+
+    failNotFound [message] content
+
+Fails the test immediately, reporting that the _content_ was not found. The
+_message_ is optional, and must be quoted.
+
+_Note: no actual search of content is done._
+
+### <a name="setup-teardown"></a> Setup/Teardown
+
+    oneTimeSetUp
+
+This function can be optionally overridden by the user in their test suite.
+
+If this function exists, it will be called once before any tests are run. It is
+useful to prepare a common environment for all tests.
+
+    oneTimeTearDown
+
+This function can be optionally overridden by the user in their test suite.
+
+If this function exists, it will be called once after all tests are completed.
+It is useful to clean up the environment after all tests.
+
+    setUp
+
+This function can be optionally overridden by the user in their test suite.
+
+If this function exists, it will be called before each test is run. It is useful
+to reset the environment before each test.
+
+    tearDown
+
+This function can be optionally overridden by the user in their test suite.
+
+If this function exists, it will be called after each test completes. It is
+useful to clean up the environment after each test.
+
+### <a name="skipping"></a> Skipping
+
+    startSkipping
+
+This function forces the remaining _assert_ and _fail_ functions to be
+"skipped", i.e. they will have no effect. Each function skipped will be recorded
+so that the total of asserts and fails will not be altered.
+
+    endSkipping
+
+This function returns calls to the _assert_ and _fail_ functions to their
+default behavior, i.e. they will be called.
+
+    isSkipping
+
+This function returns the current state of skipping. It can be compared against
+`${SHUNIT_TRUE}` or `${SHUNIT_FALSE}` if desired.
+
+### <a name="suites"></a> Suites
+
+The default behavior of shUnit2 is that all tests will be found dynamically. If
+you have a specific set of tests you want to run, or you don't want to use the
+standard naming scheme of prefixing your tests with `test`, these functions are
+for you. Most users will never use them though.
+
+    suite
+
+This function can be optionally overridden by the user in their test suite.
+
+If this function exists, it will be called when `shunit2` is sourced. If it does
+not exist, shUnit2 will search the parent script for all functions beginning
+with the word `test`, and they will be added dynamically to the test suite.
+
+    suite_addTest name
+
+This function adds a function named _name_ to the list of tests scheduled for
+execution as part of this test suite. This function should only be called from
+within the `suite()` function.
+
+---
+
+## <a name="advanced-usage"></a> Advanced Usage
+
+### <a name="some-constants-you-can-use"></a> Some constants you can use
+
+There are several constants provided by shUnit2 as variables that might be of
+use to you.
+
+*Predefined*
+
+| Constant        | Value |
+| --------------- | ----- |
+| SHUNIT\_TRUE    | Standard shell `true` value (the integer value 0). |
+| SHUNIT\_FALSE   | Standard shell `false` value (the integer value 1). |
+| SHUNIT\_ERROR   | The integer value 2. |
+| SHUNIT\_TMPDIR  | Path to temporary directory that will be automatically cleaned up upon exit of shUnit2. |
+| SHUNIT\_VERSION | The version of shUnit2 you are running. |
+
+*User defined*
+
+| Constant          | Value |
+| ----------------- | ----- |
+| SHUNIT\_CMD\_EXPR | Override which `expr` command is used. By default `expr` is used, except on BSD systems where `gexpr` is used. |
+| SHUNIT\_COLOR     | Enable colorized output. Options are 'auto', 'always', or 'none', with 'auto' being the default. |
+| SHUNIT\_PARENT    | The filename of the shell script containing the tests. This is needed specifically for Zsh support. |
+| SHUNIT\_TEST\_PREFIX | Define this variable to add a prefix in front of each test name that is output in the test report. |
+
+### <a name="error-handling"></a> Error handling
+
+The constants values `SHUNIT_TRUE`, `SHUNIT_FALSE`, and `SHUNIT_ERROR` are
+returned from nearly every function to indicate the success or failure of the
+function. Additionally the variable `flags_error` is filled with a detailed
+error message if any function returns with a `SHUNIT_ERROR` value.
+
+### <a name="including-line-numbers-in-asserts-macros"></a> Including Line Numbers in Asserts (Macros)
+
+If you include lots of assert statements in an individual test function, it can
+become difficult to determine exactly which assert was thrown unless your
+messages are unique. To help somewhat, line numbers can be included in the
+assert messages. To enable this, a special shell "macro" must be used rather
+than the standard assert calls. _Shell doesn't actually have macros; the name is
+used here as the operation is similar to a standard macro._
+
+For example, to include line numbers for a `assertEquals()` function call,
+replace the `assertEquals()` with `${_ASSERT_EQUALS_}`.
+
+_**Example** -- Asserts with and without line numbers_
+
+```shell
+#! /bin/sh
+# file: examples/lineno_test.sh
+
+testLineNo() {
+  # This assert will have line numbers included (e.g. "ASSERT:[123] ...").
+  echo "ae: ${_ASSERT_EQUALS_}"
+  ${_ASSERT_EQUALS_} 'not equal' 1 2
+
+  # This assert will not have line numbers included (e.g. "ASSERT: ...").
+  assertEquals 'not equal' 1 2
+}
+
+# Load shUnit2.
+. ../shunit2
+```
+
+Notes:
+
+1. Due to how shell parses command-line arguments, _**all strings used with
+   macros should be quoted twice**_. Namely, single-quotes must be converted to single-double-quotes, and vice-versa.<br/>
+   <br/>
+   Normal `assertEquals` call.<br/>
+   `assertEquals 'some message' 'x' ''`<br/>
+   <br/>
+   Macro `_ASSERT_EQUALS_` call. Note the extra quoting around the _message_ and
+   the _null_ value.<br/>
+   `_ASSERT_EQUALS_ '"some message"' 'x' '""'`
+
+1. Line numbers are not supported in all shells. If a shell does not support
+   them, no errors will be thrown. Supported shells include: __bash__ (>=3.0),
+   __ksh__, __mksh__, and __zsh__.
+
+### <a name="test-skipping"></a> Test Skipping
+
+There are times where the test code you have written is just not applicable to
+the system you are running on. This section describes how to skip these tests
+but maintain the total test count.
+
+Probably the easiest example would be shell code that is meant to run under the
+__bash__ shell, but the unit test is running under the Bourne shell. There are
+things that just won't work. The following test code demonstrates two sample
+functions, one that will be run under any shell, and the another that will run
+only under the __bash__ shell.
+
+_**Example** -- math include_
+```sh
+# file: examples/math.inc.
+
+add_generic() {
+  num_a=$1
+  num_b=$2
+
+  expr $1 + $2
+}
+
+add_bash() {
+  num_a=$1
+  num_b=$2
+
+  echo $(($1 + $2))
+}
+```
+
+And here is a corresponding unit test that correctly skips the `add_bash()` function when the unit test is not running under the __bash__ shell.
+
+_**Example** -- math unit test_
+```sh
+#! /bin/sh
+# file: examples/math_test.sh
+
+testAdding() {
+  result=`add_generic 1 2`
+  assertEquals \
+      "the result of '${result}' was wrong" \
+      3 "${result}"
+
+  # Disable non-generic tests.
+  [ -z "${BASH_VERSION:-}" ] && startSkipping
+
+  result=`add_bash 1 2`
+  assertEquals \
+      "the result of '${result}' was wrong" \
+      3 "${result}"
+}
+
+oneTimeSetUp() {
+  # Load include to test.
+  . ./math.inc
+}
+
+# Load and run shUnit2.
+. ../shunit2
+```
+
+Running the above test under the __bash__ shell will result in the following
+output.
+
+```console
+$ /bin/bash math_test.sh
+testAdding
+
+Ran 1 test.
+
+OK
+```
+
+But, running the test under any other Unix shell will result in the following
+output.
+
+```console
+$ /bin/ksh math_test.sh
+testAdding
+
+Ran 1 test.
+
+OK (skipped=1)
+```
+
+As you can see, the total number of tests has not changed, but the report
+indicates that some tests were skipped.
+
+Skipping can be controlled with the following functions: `startSkipping()`,
+`endSkipping()`, and `isSkipping()`. Once skipping is enabled, it will remain
+enabled until the end of the current test function call, after which skipping is
+disabled.
+
+### <a name="cmd-line-args"></a> Running specific tests from the command line.
+
+When running a test script, you may override the default set of tests, or the suite-specified set of tests, by providing additional arguments on the command line.  Each additional argument after the `--` marker is assumed to be the name of a test function to be run in the order specified.  e.g.
+
+```console
+test-script.sh -- testOne testTwo otherFunction
+```
+
+or
+
+```console
+shunit2 test-script.sh testOne testTwo otherFunction
+```
+
+In either case, three functions will be run as tests, `testOne`, `testTwo`, and `otherFunction`.  Note that the function `otherFunction` would not normally be run by `shunit2` as part of the implicit collection of tests as it's function name does not match the test function name pattern `test*`.
+
+If a specified test function does not exist, `shunit2` will still attempt to run that function and thereby cause a failure which `shunit2` will catch and mark as a failed test.  All other tests will run normally.
+
+The specification of tests does not affect how `shunit2` looks for and executes the setup and tear down functions, which will still run as expected.

+### <a name="getting-help"></a> Getting Help
+
+For help, please send requests to either the shunit2-users@forestent.com mailing
+list (archives available on the web at
+https://groups.google.com/a/forestent.com/forum/#!forum/shunit2-users) or
+directly to Kate Ward <kate dot ward at forestent dot com>.
+
+### <a name="zsh"></a> Zsh
+
+For compatibility with Zsh, there is one requirement that must be met -- the
+`shwordsplit` option must be set. There are three ways to accomplish this.
+
+1. In the unit-test script, add the following shell code snippet before sourcing
+   the `shunit2` library.
+
+   ```sh
+   setopt shwordsplit
+   ```
+
+2. When invoking __zsh__ from either the command-line or as a script with `#!`,
+   add the `-y` parameter.
+
+    ```sh
+    #! /bin/zsh -y
+    ```
+
+3. When invoking __zsh__ from the command-line, add `-o shwordsplit --` as
+   parameters before the script name.
+
+   ```console
+   $ zsh -o shwordsplit -- some_script
+   ```
