rsync uses the GNU long options package. Many of the command line
options have two variants, one short and one long. These are shown
below, separated by commas. Some options only have a long variant.
+The '=' for options that take a parameter is optional; whitespace
+can be used instead.
startdit()
dit(bf(-h, --help)) Print a short help page describing the options
renamed with a ~ extension as each file is transferred. You can
control the backup suffix using the --suffix option.
-dit(bf(--suffix SUFFIX)) This option allows you to override the default
+dit(bf(--suffix=SUFFIX)) This option allows you to override the default
backup suffix used with the -b option. The default is a ~.
dit(bf(-u, --update)) This forces rsync to skip any files for which the
option, all symbolic links are skipped.
dit(bf(-L, --copy-links)) This tells rsync to treat symbolic links just
-like ordinary files.
+like ordinary files.
+
+dit(bf(--copy-unsafe-links)) This tells rsync to treat symbolic links that
+point outside the source tree like ordinary files. Absolute symlinks are
+also treated like ordinary files, and so are any symlinks in the source
+path itself when --relative is used.
dit(bf(--safe-links)) This tells rsync to ignore any symbolic links
which point outside the destination tree. All absolute symlinks are
dit(bf(--force)) This options tells rsync to delete directories even if
they are not empty. This applies to both the --delete option and to
cases where rsync tries to copy a normal file but the destination
-contains a directory of the same name. Normally rsync will refuse to
-do a recursive directory deletion in such cases, by using --force
-the recursive deletion will be done.
+contains a directory of the same name.
-Use this option with caution!
+Since this option was added, deletions were reordered to be done depth-first
+so it is hardly ever needed anymore except in very obscure cases.
-dit(bf(-B , --block_size BLOCKSIZE)) This controls the block size used in
+dit(bf(-B , --block_size=BLOCKSIZE)) This controls the block size used in
the rsync algorithm. See the technical report for details.
-dit(bf(-e, --rsh COMMAND)) This option allows you to choose an alternative
+dit(bf(-e, --rsh=COMMAND)) This option allows you to choose an alternative
remote shell program to use for communication between the local and
remote copies of rsync. By default, rsync will use rsh, but you may
like to instead use ssh because of its high security.
You can also choose the remote shell program using the RSYNC_RSH
environment variable.
-dit(bf(--rsync-path PATH)) Use this to specify the path to the copy of
+dit(bf(--rsync-path=PATH)) Use this to specify the path to the copy of
rsync on the remote machine. Useful when it's not in your path.
-dit(bf(--exclude pattern)) This option allows you to selectively exclude
+dit(bf(--exclude=PATTERN)) This option allows you to selectively exclude
certain files from the list of files to be transferred. This is most
useful in combination with a recursive transfer.
See the section on exclude patterns for information on the syntax of
this option.
-dit(bf(--exclude-from FILE)) This option is similar to the --exclude
+dit(bf(--exclude-from=FILE)) This option is similar to the --exclude
option, but instead it adds all filenames listed in the file FILE to
the exclude list. Blank lines in FILE and lines starting with ';' or '#'
are ignored.
-dit(bf(--include pattern)) This option tells rsync to not exclude the
+dit(bf(--include=PATTERN)) This option tells rsync to not exclude the
specified pattern of filenames. This is useful as it allows you to
build up quite complex exclude/include rules.
See the section of exclude patterns for information on the syntax of
this option.
-dit(bf(--include-from FILE)) This specifies a list of include patterns
+dit(bf(--include-from=FILE)) This specifies a list of include patterns
from a file.
dit(bf(-C, --cvs-exclude)) This is a useful shorthand for excluding a
Finally in each directory any files listed in the .cvsignore file in
that directory are added to the list.
-dit(bf(--csum-length LENGTH)) By default the primary checksum used in
+dit(bf(--csum-length=LENGTH)) By default the primary checksum used in
rsync is a very strong 16 byte MD4 checksum. In most cases you will
find that a truncated version of this checksum is quite efficient, and
this will decrease the size of the checksum data sent over the link,
if a 2nd pass is required with a longer block checksum. Only use this
option if you have read the source code and know what you are doing.
-dit(bf(-T, --temp-dir DIR)) This option instructs rsync to use DIR as a
+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.
-dit(bf(--compare-dest DIR)) This option instructs rsync to use DIR as an
+dit(bf(--compare-dest=DIR)) This option instructs rsync to use DIR as an
additional directory to compare destination files against when doing
transfers. This is useful for doing transfers to a new destination while
leaving existing files intact, and then doing a flash-cutover when all
respond to requests accordingly. See the rsyncd.conf(5) man page for more
details.
-dit(bf(--config FILE)) This specifies an alternate config file than
+dit(bf(--config=FILE)) This specifies an alternate config file than
the default /etc/rsyncd.conf. This is only relevant when --daemon is
specified.
-dit(bf(--port PORT)) This specifies an alternate TCP port number to use
+dit(bf(--port=PORT)) This specifies an alternate TCP port number to use
rather than the default port 873.
dit(bf(--log-format=FORMAT)) This allows you to specify exactly what the
