 -   Daemon mode monitors changes in the whole replica directories, without honoring exclusion lists

 ## Installation
 Installation

 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.

 ## 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.
+osync v1.2 also added multiple new configuration options.
-You can upgrade all v1.0x-v1.3-dev config files by running the upgrade script
+You can upgrade all v1.0x-v1.2-dev config files by running the upgrade script
-	$ ./upgrade-v1.0x-v1.3x.sh /etc/osync/your-config-file.conf
+	$ ./upgrade-v1.0x-v1.2x.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.

-
+-----
-Osync can work in 3 modes:
+Osync can work with in three flavors: Quick sync mode, configuration file mode, and daemon mode.
-1. [:rocket: Quick sync mode](#quick-sync-mode)
+While quick sync mode is convenient to do fast syncs between some directories, a configuration file gives much more functionnality.
-2. [:gear: Configuration file mode](#configuration-file-mode)
+Please use double quotes as path delimiters. Do not use escaped characters in path names.
 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
-#### Quick sync with minimal options
+Summary mode
 ------------
 osync may 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.
 QuickSync 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.

+Running osync with a Configuration file
-
+---------------------------------------
-osync will output only file changes and errors with the following:
+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.
-	# osync.sh --initiator="/path/to/dir1" --target="/path/to/dir" --summary --errors-only --no-prefix
+Also, running sync as superuser requires to configure /etc/sudoers file.
-
+Please read the documentation about remote sync setups.
-This also works in configuration file mode.
+Once you've customized a sync.conf file, you may run osync with the following test run:

 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:

 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="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.
