+not enabled. A regular file is considered to be executable if at least one
+'x' is turned on in the source permissions.
-Without this option, all existing files (including updated files) retain

This option is inferred if you use bf(--backup) without bf(--backup-dir).
+dit(bf(--super)) This tells the receiving side to attempt super-user
+activities even if the receiving rsync wasn't run by the super-user. These
+activities include: preserving users via the bf(--owner) option, preserving
+all groups (not just the current user's groups) via the bf(--groups)
+option, and copying devices via the bf(--devices) option. This is useful
+for systems that allow such activities without being the super-user, and
+also for ensuring that you will get errors if the receiving side isn't
+being running as the super-user. To turn off super-user activities, the
+super-user can use bf(--no-super).
+
+dit(bf(--chmod)) This option tells rsync to apply one or more
+comma-separated "chmod" strings to the permission of the files in the
+transfer. The resulting value is treated as though it was the permissions
+that the sending side supplied for the file, which means that this option
+can seem to have no effect on existing files if bf(--perms) is not enabled.
+
+In addition to the normal parsing rules specified in the bf(chmod)(1)
+manpage, you can specify an item that should only apply to a directory by
+prefixing it with a 'D', or specify an item that should only apply to a
+file by prefixing it with a 'F'. For example:

-boundaries when recursing. This is useful for transferring the
-contents of only one filesystem.
+dit(bf(-x, --one-file-system)) This tells rsync to avoid crossing a
+filesystem boundary when recursing. This does not limit the user's ability
+to specify items to copy from multiple filesystems, just rsync's recursion
+through the hierarchy of each directory that the user specified, and also
+the analogous recursion on the receiving side during deletion. Also keep
+in mind that rsync treats a "bind" mount to the same device as being on the
+same filesystem.
+
+If this option is repeated, rsync omits all mount-point directories from
+the copy. Otherwise, it includes an empty directory at each mount-point it
+encounters (using the attributes of the mounted directory because those of
+the underlying mount-point directory are inaccessible).
-dit(bf(--existing)) This tells rsync not to create any new files --
-only update files that already exist on the destination.
+If rsync has been told to collapse symlinks (via bf(--copy-links) or
+bf(--copy-unsafe-links)), a symlink to a directory on another device is
+treated like a mount-point. Symlinks to non-directories are unaffected
+by this option.
-dit(bf(--ignore-existing))
-This tells rsync not to update files that already exist on
-the destination.
+dit(bf(--existing, --ignore-non-existing)) This tells rsync to skip
+updating files that do not exist yet on the destination. If this option is

-gigabyte (1024*1024*1024).
-If you want the multiplier to be 1000 instead of 1024, suffix the K, G, or
-M with a "T" (or "t") to indicate that a power of 10 is desired.
+The suffixes are as follows: "K" (or "KiB") is a kibibyte (1024),

dit(bf(-T, --temp-dir=DIR)) This option instructs rsync to use DIR as a
-scratch directory when creating temporary copies of the files
-transferred on the receiving side. The default behavior is to create
-the temporary files in the receiving directory.
+scratch directory when creating temporary copies of the files transferred
+on the receiving side. The default behavior is to create each temporary
+file in the same directory as the associated destination file.
+
+This option is most often used when the receiving disk partition does not
+have enough free space to hold a copy of the largest file in the transfer.
+In this case (i.e. when the scratch directory in on a different disk
+partition), rsync will not be able to rename each received temporary file
+over the top of the associated destination file, but instead must copy it
+into place. Rsync does this by copying the file over the top of the
+destination file, which means that the destination file will contain
+truncated data during this copy. If this were not done this way (even if
+the destination file were first removed, the data locally copied to a
+temporary file in the destination directory, and then renamed into place)
+it would be possible for the old file to continue taking up disk space (if
+someone had it open), and thus there might not be enough room to fit the
+new version on the disk at the same time.
+
+If you are using this option for reasons other than a shortage of disk
+space, you may wish to combine it with the bf(--delay-updates) option,
+which will ensure that all copied files get put into subdirectories in the
+destination hierarchy, awaiting the end of the transfer. If you don't
+have enough room to duplicate all the arriving files on the destination
+partition, another way to tell rsync that you aren't overly concerned
+about disk space is to use the bf(--partial-dir) option with a relative
+path; because this tells rsync that it is OK to stash off a copy of a
+single file in a subdir in the destination hierarchy, rsync will use the
+partial-dir as a staging area to bring over the copied file, and then
+rename it into place from there. (Specifying a bf(--partial-dir) with
+an absolute path does not have this side-effect.)
dit(bf(-y, --fuzzy)) This option tells rsync that it should look for a
basis file for any destination file that is missing. The current algorithm

+the bf(-o) option when sending to an old rsync.
dit(bf(-z, --compress)) With this option, rsync compresses the file data
as it is sent to the destination machine, which reduces the amount of data
because it takes advantage of the implicit information in the matching data
blocks that are not explicitly sent over the connection.

option in the bf(--daemon) mode section.
+dit(bf(--sockopts)) This option can provide endless fun for people
+who like to tune their systems to the utmost degree. You can set all
+sorts of socket options which may make transfers faster (or
+slower!). Read the man page for the setsockopt() system call for
+details on some of the options you may be able to set. By default no
+special socket options are set. This only affects direct socket
+connections to a remote rsync daemon. This option also exists in the
+bf(--daemon) mode section.

dit(bf(--partial)) By default, rsync will delete any partially
transferred file if the transfer is interrupted. In some circumstances
it is more desirable to keep partially transferred files. Using the
bf(--partial) option is to specify a em(DIR) that will be used to hold the
partial data (instead of writing it out to the destination file).

IMPORTANT: the bf(--partial-dir) should not be writable by other users or it
specified. For instance, instead of using bf(--partial-dir=.rsync-tmp)
along with bf(--progress), you could set RSYNC_PARTIAL_DIR=.rsync-tmp in your
environment and then just use the bf(-P) option to turn on the use of the
-.rsync-tmp dir for partial transfers. The only time that the bf(--partial)
-option does not look for this environment value is (1) when bf(--inplace) was
-specified (since bf(--inplace) conflicts with bf(--partial-dir)), or (2) when

This option uses more memory on the receiving side (one bit per file
transferred) and also requires enough free disk space on the receiving
update algorithm that is even more atomic (it uses bf(--link-dest) and a
parallel hierarchy of files).
+dit(bf(-m, --prune-empty-dirs)) This option tells the receiving rsync to get

+creation of a bunch of useless directories when the sending rsync is
+recursively scanning a hierarchy of files using include/exclude/filter

+by using a global "protect" filter. For instance, this option would ensure
+that the directory "emptydir" was kept in the file-list:
+
+quote( --filter 'protect emptydir/')
+
+Here's an example that copies all .pdf files in a hierarchy, only creating
+the necessary destination directories to hold the .pdf files, and ensures
+that any superfluous files and directories in the destination are removed
+(note the hide filter of non-directories being used instead of an exclude):
+
+quote( rsync -avm --del --include='*.pdf' -f 'hide! */' src/ dest)
+
+If you didn't want to remove superfluous destination files, the more
+time-honored options of "--include='*/' --exclude='*'" would work fine
+in place of the hide-filter (if that is more natural to you).

dit(bf(--progress)) This option tells rsync to print information
showing the progress of the transfer. This gives a bored user
something to watch.
dit(bf(--config=FILE)) This specifies an alternate config file than
the default. This is only relevant when bf(--daemon) is specified.
The default is /etc/rsyncd.conf unless the daemon is running over
-a remote shell program and the remote user is not root; in that case
+a remote shell program and the remote user is not the super-user; in that case
the default is rsyncd.conf in the current directory (typically $HOME).
dit(bf(--no-detach)) When running as a daemon, this option instructs
daemon to listen on rather than the default of 873. See also the "port"
global option in the rsyncd.conf manpage.
+dit(bf(--sockopts)) This overrides the bf(socket options) setting in the
+rsyncd.conf file and has the same syntax.
+
dit(bf(-v, --verbose)) This option increases the amount of information the
daemon logs during its startup phase. After the client connects, the
daemon's verbosity level will be controlled by the options that the client
of the transfer.
it() if the pattern ends with a / then it will only match a
directory, not a file, link, or device.
- it() if the pattern contains a wildcard character from the set
- *?[ then expression matching is applied using the shell filename
- matching rules. Otherwise a simple string match is used.
- it() the double asterisk pattern "**" will match slashes while a
- single asterisk pattern "*" will stop at slashes.
- it() if the pattern contains a / (not counting a trailing /) or a "**"
+
+ it() rsync chooses between doing a simple string match and wildcard
+ matching by checking if the pattern contains one of these three wildcard
+ characters: '*', '?', and '[' .
+ it() a '*' matches any non-empty path component (it stops at slashes).
+ it() use '**' to match anything, including slashes.
+ it() a '?' matches any character except a slash (/).
+ it() a '[' introduces a character class, such as [a-z] or [[:alpha:]].
+ it() in a wildcard pattern, a backslash can be used to escape a wildcard
+ character, but it is matched literally when no wildcards are present.
+ it() if the pattern contains a / (not counting a trailing /) or a "**",
then it is matched against the full pathname, including any leading
directories. If the pattern doesn't contain a / or a "**", then it is
matched only against the final component of the filename.
(Remember that the algorithm is applied recursively so "full filename"
can actually be any portion of a path from the starting directory on
down.)
+ it() a trailing "dir_name/***" will match both the directory (as if
+ "dir_name/" had been specified) and all the files in the directory
+ (as if "dir_name/**" had been specified). (This behavior is new for
+ version 2.6.7.)
