manpagedescription()
rsync is a program that behaves in much the same way that rcp does,
a host specification. Contacting an rsync daemon directly happens when the
source or destination path contains a double colon (::) separator after a
host specification, OR when an rsync:// URL is specified (see also the
-"CONNECTING TO AN RSYNC DAEMON OVER A REMOTE SHELL PROGRAM" section for
+"USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION" section for
an exception to this latter rule).
As a special case, if a remote source is specified without a destination,
You can also specify any remote shell you like, either by using the bf(-e)
command line option, or by setting the RSYNC_RSH environment variable.
-One common substitute is to use ssh, which offers a high degree of
-security.
-
Note that rsync must be installed on both the source and destination
machines.
destination don't have a ':' in the name. In this case it behaves like
an improved copy command.
+Finally, you can list all the (listable) modules available from a
+particular rsync daemon by leaving off the module name:
+
quote(tt(rsync somehost.mydomain.com::))
-This would list all the anonymous rsync modules available on the host
-somehost.mydomain.com. (See the following section for more details.)

manpagesection(ADVANCED USAGE)
manpagesection(CONNECTING TO AN RSYNC DAEMON)
-It is also possible to use rsync without a remote shell as the
-transport. In this case you will connect to a remote rsync daemon
-running on TCP port 873.
-
-You may establish the connection via a web proxy by setting the
-environment variable RSYNC_PROXY to a hostname:port pair pointing to
-your web proxy. Note that your web proxy's configuration must support
-proxy connections to port 873.
+It is also possible to use rsync without a remote shell as the transport.
+In this case you will directly connect to a remote rsync daemon, typically
+using TCP port 873. (This obviously requires the daemon to be running on
+the remote system, so refer to the STARTING AN RSYNC DAEMON TO ACCEPT
+CONNECTIONS section below for information on that.)
Using rsync in this way is the same as using it with a remote shell except
that:

+
+Some modules on the remote daemon may require authentication. If so,
you will receive a password prompt when you connect. You can avoid the
password prompt by setting the environment variable RSYNC_PASSWORD to
the password you want to use or using the bf(--password-file) option. This
WARNING: On some systems environment variables are visible to all
users. On those systems using bf(--password-file) is recommended.
-manpagesection(CONNECTING TO AN RSYNC DAEMON OVER A REMOTE SHELL PROGRAM)
-
-It is sometimes useful to be able to set up file transfers using rsync
-daemon capabilities on the remote machine, while still using ssh or
-rsh for transport. This is especially useful when you want to connect
-to a remote machine via ssh (for encryption or to get through a
-firewall), but you still want to have access to the rsync daemon
-features (see RUNNING AN RSYNC DAEMON OVER A REMOTE SHELL PROGRAM,
-below).
-
-From the user's perspective, using rsync in this way is the same as
-using it to connect to an rsync daemon, except that you must
-explicitly set the remote shell program on the command line with
-bf(--rsh=COMMAND). (Setting RSYNC_RSH in the environment will not turn on
-this functionality.)
-
-In order to distinguish between the remote-shell user and the rsync
-daemon user, you can use '-l user' on your remote-shell command:
+You may establish the connection via a web proxy by setting the
+environment variable RSYNC_PROXY to a hostname:port pair pointing to
+your web proxy. Note that your web proxy's configuration must support
+proxy connections to port 873.
-verb( rsync -av --rsh="ssh -l ssh-user" \
- rsync-user@host::module[/path] local-path)
+manpagesection(USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION)
+
+It is sometimes useful to use various features of an rsync daemon (such as
+named modules) without actually allowing any new socket connections into a
+system (other than what is already required to allow remote-shell access).
+Rsync supports connecting to a host using a remote shell and then spawning
+a single-use "daemon" server that expects to read its config file in the
+home dir of the remote user. This can be useful if you want to encrypt a
+daemon-style transfer's data, but since the daemon is started up fresh by
+the remote user, you may not be able to use features such as chroot or
+change the uid used by the daemon. (For another way to encrypt a daemon
+transfer, consider using ssh to tunnel a local port to a remote machine and
+configure a normal rsync daemon on that remote host to only allow
+connections from "localhost".)
+
+From the user's perspective, a daemon transfer via a remote-shell
+connection uses nearly the same command-line syntax as a normal
+rsync-daemon transfer, with the only exception being that you must
+explicitly set the remote shell program on the command-line with the
+bf(--rsh=COMMAND) option. (Setting the RSYNC_RSH in the environment
+will not turn on this functionality.) For example:
+
+verb( rsync -av --rsh=ssh host::module /dest)
+
+If you need to specify a different remote-shell user, keep in mind that the
+user@ prefix in front of the host is specifying the rsync-user value (for a
+module that requires user-based authentication). This means that you must
+give the '-l user' option to ssh when specifying the remote-shell:
+
+verb( rsync -av -e "ssh -l ssh-user" rsync-user@host::module /dest)
The "ssh-user" will be used at the ssh level; the "rsync-user" will be
-used to check against the rsyncd.conf on the remote host.
+used to log-in to the "module".
-manpagesection(RUNNING AN RSYNC DAEMON)
+manpagesection(STARTING AN RSYNC DAEMON TO ACCEPT CONNECTIONS)
-An rsync daemon is configured using a configuration file. Please see the
-rsyncd.conf(5) man page for more information. By default the configuration
-file is called /etc/rsyncd.conf (unless the daemon is spawned via a remote
-shell--see below).
+In order to connect to an rsync daemon, the remote system needs to have a
+daemon already running (or it needs to have configured something like inetd
+to spawn an rsync daemon for incoming connections on a particular port).
+For full information on how to start a daemon that will handling incoming
+socket connections, see the rsyncd.conf(5) man page -- that is the config
+file for the daemon, and it contains the full details for how to run the
+daemon (including stand-alone and inetd configurations).
-manpagesection(RUNNING AN RSYNC DAEMON OVER A REMOTE SHELL PROGRAM)
-
-See the rsyncd.conf(5) man page for full information on the rsync
-daemon configuration file.
-
-Several configuration options will not be available unless the remote
-user is root (e.g. chroot, uid, gid, etc.). There is no need to
-configure inetd or the services map to include the rsync daemon port
-if you run an rsync daemon only via a remote shell program.
-
-To run an rsync daemon out of a single-use ssh key, see this section
-in the rsyncd.conf(5) man page.
+If you're using one of the remote-shell transports for the transfer, there is
+no need to manually start an rsync daemon.

startdit()
-dit(bf(-h, --help)) Print a short help page describing the options
-available in rsync.
+dit(bf(--help)) Print a short help page describing the options
+available in rsync and exit. For backward-compatibility with older
+versions of rsync, the same help output can also be requested by using
+the bf(-h) option without any other args.
dit(bf(--version)) print the rsync version number and exit.
dit(bf(-a, --archive)) This is equivalent to bf(-rlptgoD). It is a quick
way of saying you want recursion and want to preserve almost
-everything. The only exception to this is if bf(--files-from) was
+everything (with -H being a notable omission).
+The only exception to the above equivalence is when bf(--files-from) is
specified, in which case bf(-r) is not implied.
Note that bf(-a) bf(does not preserve hardlinks), because
finding multiply-linked files is expensive. You must separately
specify bf(-H).
+dit(--no-OPTION) You may turn off one or more implied options by prefixing
+the option name with "no-". Not all options may be prefixed with a "no-":
+only options that are implied by other options (e.g. bf(--no-D),
+bf(--no-perms)) or have different defaults in various circumstances
+(e.g. bf(--no-whole-file), bf(--no-blocking-io), bf(--no-dirs)). You may
+specify either the short or the long option name after the "no-" prefix
+(e.g. bf(--no-R) is the same as bf(--no-relative)).
+
+For example: if you want to use bf(-a) (bf(--archive)) but don't want
+bf(-o) (bf(--owner)), instead of converting bf(-a) into bf(-rlptgD), you
+could specify bf(-a --no-o) (or bf(-a --no-owner)).
+
+The order of the options is important: if you specify bf(--no-r -a), the
+bf(-r) option would end up being turned on, the opposite of bf(-a --no-r).
+Note also that the side-effects of the bf(--files-from) option are NOT
+positional, as it affects the default state of several options and sligntly
+changes the meaning of bf(-a) (see the bf(--files-from) option for more
+details).
+
dit(bf(-r, --recursive)) This tells rsync to copy directories
recursively. See also bf(--dirs) (bf(-d)).
names specified on the command line are sent to the server rather than
just the last parts of the filenames. This is particularly useful when
you want to send several different directories at the same time. For
-example, if you used the command
+example, if you used this command:
-quote(tt( rsync /foo/bar/foo.c remote:/tmp/))
+quote(tt( rsync -av /foo/bar/baz.c remote:/tmp/))
-then this would create a file called foo.c in /tmp/ on the remote
+... this would create a file called baz.c in /tmp/ on the remote
machine. If instead you used
-quote(tt( rsync -R /foo/bar/foo.c remote:/tmp/))
+quote(tt( rsync -avR /foo/bar/baz.c remote:/tmp/))
-then a file called /tmp/foo/bar/foo.c would be created on the remote
+then a file called /tmp/foo/bar/baz.c would be created on the remote
machine -- the full path name is preserved. To limit the amount of
-path information that is sent, do something like this:
+path information that is sent, you have a couple options: (1) With
+a modern rsync on the sending side (beginning with 2.6.7), you can
+insert a dot dir into the source path, like this:
-quote(
-tt( cd /foo)nl()
-tt( rsync -R bar/foo.c remote:/tmp/)nl()
-)
+quote(tt( rsync -avR /foo/./bar/baz.c remote:/tmp/))
-That would create /tmp/bar/foo.c on the remote machine.
+That would create /tmp/bar/baz.c on the remote machine. (Note that the
+dot dir must followed by a slash, so "/foo/." would not be abbreviated.)
+(2) For older rsync versions, you would need to use a chdir to limit the
+source path. For example, when pushing files:
-dit(bf(--no-relative)) Turn off the bf(--relative) option. This is only
-needed if you want to use bf(--files-from) without its implied bf(--relative)
-file processing.
+quote(tt( (cd /foo; rsync -avR bar/baz.c remote:/tmp/) ))
+
+(Note that the parens put the two commands into a sub-shell, so that the
+"cd" command doesn't remain in effect for future commands.)
+If you're pulling files, use this idiom (which doesn't work with an
+rsync daemon):
+
+quote(
+tt( rsync -avR --rsync-path="cd /foo; rsync" \ )nl()
+tt( remote:bar/baz.c /tmp/)
+)
dit(bf(--no-implied-dirs)) When combined with the bf(--relative) option, the
implied directories in each path are not explicitly duplicated as part
renamed as each file is transferred or deleted. You can control where the
backup file goes and what (if any) suffix gets appended using the
bf(--backup-dir) and bf(--suffix) options.
-Note that if you don't specify bf(--backup-dir), the bf(--omit-dir-times)
-option will be enabled.
+
+Note that if you don't specify bf(--backup-dir), (1) the
+bf(--omit-dir-times) option will be implied, and (2) if bf(--delete) is
+also in effect (without bf(--delete-excluded)), rsync will add a protect
+filter-rule for the backup suffix to the end of all your existing excludes
+(e.g. -f "P *~"). This will prevent previously backed-up files from being
+deleted. Note that if you are supplying your own filter rules, you may
+need to manually insert your own exclude/protect rule somewhere higher up
+in the list so that it has a high enough priority to be effective (e.g., if
+your rules specify a trailing inclusion/exclusion of '*', the auto-added
+rule would never be reached).
dit(bf(--backup-dir=DIR)) In combination with the bf(--backup) option, this
tells rsync to store all backups in the specified directory. This is
rsync will be unable to update a file in-place that is not writable by the
receiving user.
+dit(bf(--append)) This causes rsync to update a file by appending data onto
+the end of the file, which presumes that the data that already exists on
+the receiving side is identical with the start of the file on the sending
+side. If that is not true, the file will fail the checksum test, and the
+resend will do a normal bf(--inplace) update to correct the mismatched data.
+Only files on the receiving side that are shorter than the corresponding
+file on the sending side (as well as new files) are sent.
+Implies bf(--inplace), but does not conflict with bf(--sparse) (though the
+bf(--sparse) option will be auto-disabled if a resend of the already-existing
+data is required).
+
dit(bf(-d, --dirs)) Tell the sending side to include any directories that
are encountered. Unlike bf(--recursive), a directory's contents are not copied
-unless the directory was specified on the command-line as either "." or a
-name with a trailing slash (e.g. "foo/"). Without this option or the
+unless the directory name specified is "." or ends with a trailing slash
+(e.g. ".", "dir/.", "dir/", etc.). Without this option or the
bf(--recursive) option, rsync will skip all directories it encounters (and
-output a message to that effect for each one).
+output a message to that effect for each one). If you specify both
+bf(--dirs) and bf(--recursive), bf(--recursive) takes precedence.
dit(bf(-l, --links)) When symlinks are encountered, recreate the
symlink on the destination.
"disk" is actually a networked filesystem). This is the default when both
the source and destination are specified as local paths.
-dit(bf(--no-whole-file)) Turn off bf(--whole-file), for use when it is the
-default.
-
dit(bf(-p, --perms)) This option causes rsync to set the destination
permissions to be the same as the source permissions.
the directories on the receiving side, it is a good idea to use bf(-O).
This option is inferred if you use bf(--backup) without bf(--backup-dir).
+dit(bf(--chmod)) This options tells rsync to apply the listed "chmod" pattern
+to the permission of the files on the destination. In addition to the normal
+parsing rules specified in the chmod 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:
+
+quote(--chmod=Dg+s,ug+w,Fo-w,+X)
+
+It is also legal to specify multiple bf(--chmod) options.
+
dit(bf(-n, --dry-run)) This tells rsync to not do any file transfers,
instead it will just report the actions it would have taken.
dit(bf(-S, --sparse)) Try to handle sparse files efficiently so they take
-up less space on the destination.
+up less space on the destination. Conflicts with bf(--inplace) because it's
+not possible to overwrite data in a sparse fashion.
NOTE: Don't use this option when the destination is a Solaris "tmpfs"
filesystem. It doesn't seem to handle seeks over null regions
boundaries when recursing. This is useful for transferring the
contents of only one filesystem.
-dit(bf(--existing)) This tells rsync not to create any new files --
-only update files that already exist on the destination.
+dit(bf(-x, --one-file-system)) This tells rsync to avoid recursing into a
+directory that is the mount-point for another filesystem, including (as of
+2.6.7), "bind" mount-points. You can still copy the contents of multiple
+file systems if you include a source dir from each file system -- this just
+limits rsync's directory-recursion algorithm.
+
+Rsync will copy the directory at each encountered mount-point unless this
+option is repeated. Note, however, that the attributes of this mount-point
+directory are copied from those currently visible in the filesystem, not
+the inaccessible attributes of the underlying directory.
+
+This option does not affect the "collapsing" of symlinks that options such
+as bf(--copy-links) perform, irrespective of what filesystem the symlink's
+referent may be on.
+
+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
+combined with the bf(--ignore-existing) option, no files will be updated
+(which can be useful if all you want to do is to delete missing files).
-dit(bf(--ignore-existing))
-This tells rsync not to update files that already exist on
-the destination.
+dit(bf(--ignore-existing)) This tells rsync to skip updating files that
+already exist on the destination. See also bf(--ignore-non-existing).
dit(bf(--remove-sent-files)) This tells rsync to remove from the sending
side the files and/or symlinks that are newly created or whose content is
option or mark the rules as only matching on the sending side (see the
include/exclude modifiers in the FILTER RULES section).
-This option has no effect unless directory recursion is enabled.
+Prior to rsync 2.6.7, this option would have no effect unless bf(--recursive)
+was in effect. Beginning with 2.6.7, deletions will also occur when bf(--dirs)
+(bf(-d)) is in effect, but only for directories whose contents are being copied.
This option can be dangerous if used incorrectly! It is a very good idea
to run first using the bf(--dry-run) option (bf(-n)) to see what files would be
dit(bf(--max-size=SIZE)) This tells rsync to avoid transferring any
file that is larger than the specified SIZE. The SIZE value can be
-suffixed with a letter to indicate a size multiplier (K, M, or G) and
+suffixed with a string to indicate a size multiplier, and
may be a fractional value (e.g. "bf(--max-size=1.5m)").
+The suffixes are as follows: "K" (or "KiB") is a kibibyte (1024),
+"M" (or "MiB") is a mebibyte (1024*1024), and "G" (or "GiB") is a
+gibibyte (1024*1024*1024).
+If you want the multiplier to be 1000 instead of 1024, use "KB",
+"MB", or "GB". (Note: lower-case is also accepted for all values.)
+Finally, if the suffix ends in either "+1" or "-1", the value will
+be offset by one byte in the indicated direction.
+
+Examples: --max-size=1.5mb-1 is 1499999 bytes, and --max-size=2g+1 is
+2147483649 bytes.
+
+dit(bf(--min-size=SIZE)) This tells rsync to avoid transferring any
+file that is smaller than the specified SIZE, which can help in not
+transferring small, junk files.
+See the bf(--max-size) option for a description of SIZE.
+
dit(bf(-B, --block-size=BLOCKSIZE)) This forces the block size used in
the rsync algorithm to a fixed value. It is normally selected based on
the size of each file being updated. See the technical report for details.
remote shell em(COMMAND) will be used to run an rsync daemon on the

+RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION" above.
Command-line arguments are permitted in COMMAND provided that COMMAND is
-presented to rsync as a single argument. For example:
+presented to rsync as a single argument. You must use spaces (not tabs
+or other whitespace) to separate the command and args from each other,
+and you can use single- and/or double-quotes to preserve spaces in an
+argument (but not backslashes). Note that doubling a single-quote
+inside a single-quoted string gives you a single-quote; likewise for
+double-quotes (though you need to pay attention to which quotes your
+shell is parsing and which quotes rsync is parsing). Some examples:
-quote(tt( -e "ssh -p 2234"))
+quote(
+tt( -e 'ssh -p 2234')nl()
+tt( -e 'ssh -o "ProxyCommand nohup ssh firewall nc -w1 %h %p"')nl()
+)
(Note that ssh users can alternately customize site-specific connect
options in their .ssh/config file.)
dit(bf(-F)) The bf(-F) option is a shorthand for adding two bf(--filter) rules to
your command. The first time it is used is a shorthand for this rule:
-quote(tt( --filter=': /.rsync-filter'))
+quote(tt( --filter='dir-merge /.rsync-filter'))
This tells rsync to look for per-directory .rsync-filter files that have
been sprinkled through the hierarchy and use their rules to filter the
files in the transfer. If bf(-F) is repeated, it is a shorthand for this
rule:
-quote(tt( --filter='- .rsync-filter'))
+quote(tt( --filter='exclude .rsync-filter'))
This filters out the .rsync-filter files themselves from the transfer.
See the FILTER RULES section for detailed information on this option.
-dit(bf(--exclude-from=FILE)) This option is similar to the bf(--exclude)
-option, but instead it adds all exclude patterns listed in the file
-FILE to the exclude list. Blank lines in FILE and lines starting with
-';' or '#' are ignored.
-If em(FILE) is bf(-) the list will be read from standard input.
+dit(bf(--exclude-from=FILE)) This option is related to the bf(--exclude)
+option, but it specifies a FILE that contains exclude patterns (one per line).
+Blank lines in the file and lines starting with ';' or '#' are ignored.
+If em(FILE) is bf(-), the list will be read from standard input.
dit(bf(--include=PATTERN)) This option is a simplified form of the
bf(--filter) option that defaults to an include rule and does not allow
See the FILTER RULES section for detailed information on this option.
-dit(bf(--include-from=FILE)) This specifies a list of include patterns
-from a file.
-If em(FILE) is "-" the list will be read from standard input.

+Blank lines in the file and lines starting with ';' or '#' are ignored.

The file names that are read from the FILE are all relative to the

blocks that are not explicitly sent over the connection.

at both ends.

ssh prefers non-blocking I/O.)
-dit(bf(--no-blocking-io)) Turn off bf(--blocking-io), for use when it is the

dit(bf(-i, --itemize-changes)) Requests a simple itemized list of the
changes that are being made to each file, including attribute changes.
This is exactly the same as specifying bf(--log-format='%i %n%L').
+If you repeat the option, unchanged files will also be output, but only
+if the receiving rsync is at least version 2.6.7 (you can use bf(-vv)
+with older versions of rsync, but that also turns on the output of other
+verbose messages).
The "%i" escape has a cryptic output that is 9 letters long. The general
format is like the string bf(UXcstpoga)), where bf(U) is replaced by the
touched directory) unless the itemized-changes escape (%i) is included in
the string, in which case the logging of names increases to mention any
item that is changed in any way (as long as the receiving side is at least
-2.6.4). See the bf(--itemized-changes) option for a description of the
+2.6.4). See the bf(--itemize-changes) option for a description of the
output of "%i".
The bf(--verbose) option implies a format of "%n%L", but you can use
on the file transfer, allowing you to tell how effective the rsync
algorithm is for your data.
+dit(bf(-h, --human-readable)) Output numbers in a more human-readable format.
+Large numbers may be output in larger units, with a K (1024), M (1024*1024),
+or G (1024*1024*1024) suffix.
+
+dit(bf(--si)) Similar to the bf(--human-readable) option, but using powers
+of 1000 instead of 1024.

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
untimely deletion of partial-dir items on the receiving side. An example:
the above bf(--partial-dir) option would add an "bf(--exclude=.rsync-partial/)"
rule at the end of any other filter rules. Note that if you are
-supplying your own filter rules, you may need to manually insert a
-rule for this directory exclusion somewhere higher up in the list so that
+supplying your own exclude rules, you may need to manually insert your own
+exclude/protect rule somewhere higher up in the list so that
it has a high enough priority to be effective (e.g., if your rules specify
-a trailing bf(--exclude='*') rule, the auto-added rule would never be
+a trailing inclusion/exclusion of '*', the auto-added rule would never be
reached).
IMPORTANT: the bf(--partial-dir) should not be writable by other users or it
transfer, at which time all the files are renamed into place in rapid
succession. This attempts to make the updating of the files a little more
atomic. By default the files are placed into a directory named ".~tmp~" in
-each file's destination directory, but you can override this by specifying
-the bf(--partial-dir) option. (Note that RSYNC_PARTIAL_DIR has no effect
-on this value, nor is bf(--partial-dir) considered to be implied for the
-purposes of the daemon-config's "refuse options" setting.)

This option uses more memory on the receiving side (one bit per file
transferred) and also requires enough free disk space on the receiving
side to hold an additional copy of all the updated files. Note also that

+
+ it() rsync chooses between doing a simple string match and wildcard

+ characters: '*', '?', and '[' .
+ it() a '*' matches any non-empty path component (it stops at slashes).

then it is matched against the full pathname, including any leading
directories. If the pattern doesn't contain a / or a "**", then it is

(Remember that the algorithm is applied recursively so "full filename"
can actually be any portion of a path from the starting directory on
down.)
