Remote file copy (Synchronize file trees). As of macOS 15.4, openrsync tool is linked to /usr/bin/rsync so you can run it as rsync. Openrsync accepts only a subset of rsync’s command line arguments.
To manually install a full GPLv3 version of rsync with homebrew use: brew install rsync

The openrsync utility synchronises files in the destination directory with one or more source files.
Either the source or the destination directory may be remote, but not both.
Options
-0, --from0
Use a null ('\0') character, rather than a newline to separate filenames read from: --exclude-from,
--include-from, --files-from, and any merged files specified in --filter rules.
Does not affect --cvs-exclude.
-4, --ipv4
Use IPv4 when connecting to a remote host, or binding to a local address.
If openrsync is configured to use an --rsh program named “ssh”, then it will pass -4 to it.
-6, --ipv6
Use IPv6 when connecting to a remote host, or binding to a local address.
As with the -4 option, openrsync will pass -6 to the --rsh program if it is named “ssh”.
-8, --8-bit-output
Do not escape high-bit characters in the output (which is otherwise the default).
-a, --archive
Shorthand for -Dgloprt.
--address=sourceaddr
When connecting to an rsync daemon, use sourceaddr as the source address for connections,
which is useful on machines with multiple interfaces.
--append
If the destination file exists and is shorter than the source file then rsync will append the
difference to the destination file. If after the transfer the whole-file checksums do not
match then the destination file will be updated via the usual block-based delta-merge protocol.
This option implies --inplace.
-b, --backup
Make a backup of changed files with ~ suffix.
--backup-dir directory
When combined with the --backup flag, openrsync will store backups of files being replaced in
the designated backup directory on the receiving side. Can be combined with the --suffix
flag to name the backup files with a suffix. The default is to not append a suffix.
If specified as a relative path, the backup directory will be contained within the copied tree,
and may cause conflicts or be subject to --delete rules. It is advised to use an
absolute path outside of the copied tree, or a relative path such as "../".
-B, --block-size=BLOCKSIZE
Specify the block size to be used for file transfers. The upper bound is 512M, but it is enforced
only if a differential transfer is required.
--blocking-io
This flag is ignored by openrsync, but is accepted for compatibility.
--bwlimit limit
Limit transfer speed to limit bytes/sec. The limit may also contain any of the suffixes described
in the --max-size definition of size.
--cache
Use the operating system buffer cache when reading and writing files. This is the default on all
operating systems except macOS, where openrsync sets F_NOCACHE by default to limit
memory growth. Setting this option will enabling caching by not setting any flags.
--no-cache
Sets O_DIRECT when reading and writing files to avoid using the buffer cache. Setting this option
can avoid filling the cache with files that will not be read again, such as during a backup.
This is the default on macOS, where F_NOCACHE is used instead of O_DIRECT.
-c, --checksum
Use full-file checksums to determine which files have changed and should be transferred, rather than
the usual file size and modification time "quick check".
--checksum-seed=NUM
Use NUM as the seed for both the 4-byte block and MD4 file checksums.
By default, NUM is randomly generated, but if set to zero directs openrsync to use time(3) as the
checksum seed.
--chmod=MODE
Modify the permissions on files that are transferred, overriding the original source permissions.
Only has an effect if --perms is specified as well. The MODE string can be a comma
separated list of literal (755) or relative (g+w) permissions.
openrsync also supports two additional extensions to relative permissions, adding a ‘D’ or ‘F’ infront
of the relative permissions will apply the changes to only directories or files respectively.
For example: -chmod=Dg+w,Fo-w
--compare-dest=directory
Use directory as an alternate base directory to compare files against on the destination machine.
If file in directory is found and identical to the sender's file, the file will not
be transferred. Multiple --compare-dest directories may be provided. If directory is a relative path,
it is relative to the destination directory.
-z, --compress
Compress file data during transfer to reduce the amount of data transferred.
--compress-level=NUM
Set the compression level used by --compress.
--contimeout=seconds
Set the connection timeout in seconds.
Exit if no connection established within the specified time. The default is 0, which means no timeout.
--copy-dest=directory
Use directory as an alternate base directory to compare files against on the destination machine.
If file in directory is found and identical to the sender's file, the file will be
locally copied. Multiple --copy-dest directories may be provided.
If directory is a relative path, it is relative to the destination directory.
-L, --copy-links
Copy targets of symbolic links, rather than the link itself.
--copy-unsafe-links
Copy targets of symbolic links that are unsafe (absolute symlinks or where the target reaches outside
the copied tree).
-k, --copy-dirlinks
Copy targets of symbolic links that point to directories only.
-C, --cvs-exclude
Exclude a common list of files as CVS would. The patterns deployed are specifically:
RCS SCCS CVS CVS.adm
RCSLOG cvslog.* tags TAGS
.make.state .nse_depinfo *~ #*
.#* ,* _$* *$
*.old *.bak *.BAK *.orig
*.rej .del-* *.a *.olb
*.o *.obj *.so *.exe
*.Z *.elc *.ln core
.svn/
Followed by any patterns included in $HOME/.cvsignore and the CVSIGNORE environment variable.
The -C flag also adds a “dir-merge” CVS rule to include per-dir .cvsignore files.
All of these rules are appended to the end of the filter list with the equivalent of specifying
-f “-C” -f “:C”.
-D Also transfer device and special files. Shorthand for --devices --specials.
--del, --delete
Delete files in directory not found in source directories. Only applicable with -r.
--delay-updates
Delay updates of (only) plain files until all other operations are complete.
This is done to be more atomic. Requires extra space in the destination directory up to the amount
of the whole tree.
--delete-before
Execute the above described --delete behavior before the transfer begins.
This is the default timing when --delete is used.
This option is mutually exclusive with --delete-during, --delete-delay, and --delete-after.
--delete-during
Execute the above described --delete behavior as the transfer happens, right before each directory
to be transferred is checked for updates. This option is mutually exclusive with --delete-before,
--delete-delay, and --delete-after.
--delete-delay
Execute the above described --delete behavior after the transfer happens, but collect the list to
be deleted right before each directory to be transferred is checked for updates. This
option is mutually exclusive with --delete-before, --delete-during, and --delete-after.
--delete-after
Execute the above described --delete behavior after the transfer has completed.
This option is mutually exclusive with --delete-before, --delete-during, and --delete-delay.
--delete-excluded
When used in combination with any one of the above --delete options, supplied --exclude patterns
will not prevent a file from being deleted.
-d, --dirs
Copies directories, which are normally skipped unless --recursive is specified.
Directory contents are not copied, unless the path specified includes a trailing slash (“dir/”),
or is the literal “.”.
--exclude pattern
Exclude files matching pattern.
--exclude-from=file
Load patterns and rules from file.
---extended-attributes
Apple specific option to copy extended attributes, resource forks, and ACLs.
Requires at least Mac OS X 10.4 or suitably patched rsync.
-E, --executability
Preserve the executability of regular files (i.e., a file is "executable" if at least one 'x' mode
bit is enabled in its permissions). If the source file is executable, then for each 'r' mode
bit enabled in the destination file's permissions, the corresponding 'x' mode bit will be enabled.
If the source file is not executable then all ugo 'x' mode bits of the destination file
will be disabled. This option has no effect if --perms is also specified.
--files-from=filespec
Load list of files to transfer (as opposed to the command line) from filespec.
Filespec can be of the form hostname:port:path.
--force
Force deletion of non-empty directories about to be replaced by a non-directory.
This option has no effect if any of the --delete options are present.
--ignore-errors
Works in conjunction with --delete to delete files despite I/O errors.
-y, --fuzzy
Look for files in the destination directory that might be the same to use as a basis to avoid
copying the entire file. The first file with an identical size and modification time is
used to try to reduce the total amount of data that has to be transferred.
Note that the use of the --delete option might get rid of any potential fuzzy-matches, so either
use --delete-after or specify some exclusions to prevent this.
--ignore-existing
Ignore files that already exist.
--ignore-non-existing, --existing
Ignore files that do not already exist (do not create them).
-I, --ignore-times
Do not skip based on file size and modification time.
--include pattern
Include files matching pattern.
--include-from=file
Load patterns and rules from file.
--devices
Also transfer device files.
-e program, --rsh=program
Specify alternative communication program, defaults to ssh(1). The RSYNC_RSH environment variable
will be used if an -e option is not present. Note that openrsync will generally handle quotes,
but it makes no attempt to deal with escape sequences. In particular, escaped quotation marks
will not be escaped.
-F Adds a standard .rsync-filter dir-merge filter rule. Specifically, -F will add “: /.rsync-filter”
the first time it is seen, and “- .rsync-filter” the second time it is seen.
Subsequent uses have no effect.
-f filter, --filter=filter
Process filter against the global filter chain. The specified filter may be a rule to include a
filter file, or to include a per-directory filter file. Regular filter files are processed
immediately, while per-directory filter files are processed as directories are encountered.
See PATTERNS AND RULES for more details about the syntax and capabilities of openrsync filters.
-g, --group
Set the group name to match the source. For example, group "kristaps" with ID 1000 on a remote
server is matched to group "kristaps" on the local machine with ID 2000. If --numeric-ids is also
given or if the remote group name is unknown on the local machine, set the numeric group ID to
match the source instead.
-H, --hard-links
Attempt to preserve hard links within the list of files transferred.
-h, ---human-readable
Display numbers of bytes in human readable units. If specified once, uses units of 1000, if
specified twice uses units of 1024.
--help Print a brief description of all options.
-l, --links
Also transfer symbolic links. The link is transferred as a standalone file: if the destination
does not exist, it will be broken.
--inplace
Avoid creating temporary files, instead operating on files directly in place in the destination.
This option has some notable trade-offs that must be considered prior to using it. For example,
hardlinks will not be broken even if a file is no longer hardlinked in the source directory.
--keep-dirlinks
When a directory is sent, and the receiving side has a symlink to a directory in that place,
follow that symlink and place the directory's contents in that symlinked dir.
--link-dest=directory
Use directory as an alternate base directory to compare files against on the destination machine.
If file in directory is found and identical to the sender's file, the file will be hardlinked.
Multiple --compare-dest directories may be provided. If directory is a relative path, it is
relative to the destination directory.
--list-only
Instead of transferring files, only list them. This option is implied if there is only a single
source argument and no destination argument.
--max-delete MAX
Once MAX files have been deleted, do not delete any more files.
--max-size size
Don't transfer any file that is larger than size bytes. Alternatively size may instead use a
multiplier (such as 0B, 100B, 1023B, 1K, 1.5K, 5.5M; or any sequence with a case-insensitive
terminal scale multiplier of B, K, M, G, T, P, or E; corresponding to bytes, kilobytes, and so on)
to specify the size.
--min-size size
Don't transfer any file that is smaller than size bytes. See --max-size on the definition of size.
--modify-window sec
When comparing file modification times for the purpose of speeding up transfers consider offsets
of up to sec seconds the same.
-n, --dry-run
Do not actually modify the destination. Mainly useful in combination with -v.
--no-motd
Do not display the Message of the Day.
--numeric-ids
Ignore user and group names, use numeric user and group IDs only.
Has no effect unless -g or -o is also given.
-O, --omit-dir-times
Do not perserve the modification times of directories.
This can be expensive when the directories reside on NFS. This option is inferred if you use
--backup without --backup-dir.
-o, --owner
Set the user name to match the source, with similar matching logic as for -g.
If --numeric-ids is also given or if the remote user name is unknown on the local machine,
set the numeric user ID to match the source instead. Only works if run as root.
-P Shorthand for --partial --progress.
-p, --perms
Set destination file or directory permissions to match the source when it is updated.
--partial
Do not remove partially transferred files if openrsync is interrupted, which opens up the
possibility for them to be easily resumed later.
--partial-dir=DIR
Store all partially transferred files in DIR to allow an interrupted transfer to resume without
re-transferring files. Implies -partial.
--password-file=pwfile
Define a file to read the password from when connecting to an rsync daemon. The password should
be written on the first line of the file, and may have a terminating newline. The pwfile is
expected to not be readable by 'other', and to be owned by root if openrsync is running as root.
--port=service
Specify an alternative TCP port number. The service can be given as a decimal integer or as a
name to be looked up in the services(5) database. The default is “rsync”.
-m, --prune-empty-dirs
Prune empty directories from the file list on the receiver side. Empty directories may be
excluded from pruning with an exclude or protect filter rule. A directory wich only contains
other empty, non-excluded directories, is also considered empty.
-q, --quiet
Suppress all non-error related informational messages.
--progress
Periodically report file transfer progress.
--protocol=VER
Force openrsync to operate using the specified protocol version. Normally the protocol
version is negotiated automatically, but an older protocol version can be forced with this flag.
-r, --recursive
If source designates a directory, synchronise the directory and the entire subtree connected at
that point. If source ends with a slash, only the subtree is synchronised, not the source
directory itself. If source is a file, this has no effect.
--read-batch=file
Read a batch file previously prepared by openrsync from file. See the --write-batch option
for a description of a batch file. When reading a batch file, the source arguments are
optional and ignored if specified.
--remove-source-files
Remove source files as they are transferred into directory. Files are only removed once
they are confirmed to be fully in place. By default openrsync will delete files as the
transfer progresses, but given its asynchronous nature there may be a noticeable delay
between a given file finishing its transfer and its subsequent removal.
When combined with --delay-updates, files will be removed in a larger batch toward the
end of the transfer.
-R, --relative
Normally, pathnames on the commandline omit the directory components.
This option will include the dir components.
--no-implied-dirs
Changes the default behavior of --relative such that implied directories do not have
their attributes modified, or are created with default attributes, rather than the source
attributes, if they do not exist. This allows the implied directories to differ, including
being a symlink on one side and a real directory on the other.
--rsync-path=program
Run program on the remote host instead of the default rsync.
--size-only
Skip files whose sizes match (regardless of timestamp).
--safe-links
Skip any symlinks that are unsafe (absolute symlinks or where the target is outside the copied tree).
--sockopts=sockopts
Set custom sockopts on the socket created to communicate with an rsync daemon. sockopts should
be of the form “name[=value][,...]”, where name matches an SO_* option described in
setsockopt(2). Note that only the following options are currently supported:
SO_KEEPALIVE
SO_REUSEADDR
SO_SNDBUF
SO_RCVBUF
SO_SNDLOWAT
SO_RCVLOWAT
SO_SNDTIMEO
SO_RCVTIMEO
SO_REUSEPORT May not be available on all systems.
-S, --sparse
Attempt to efficiently handle sparse files.
--specials
Also transfer fifo and unix domain socket files.
--stats
Print verbose statistics about the transfer at the end of the run.
Provides details about how much data transfer was saved by openrsync.
--suffix suffix
Sets the suffix to be appended to filenames when creating backups on the receiver before
replacing files. Defaults to ~ except when combined with --backup-dir where the default is an
empty string.
--super
Always attempt traditionally super-user activities. This flag mostly interacts with the --owner,
--group, and --devices options, which may be permitted to unprivileged users on the
receiving end in some configurations. --no-super is also supported to avoid them entirely.
-T, --temp-dir=directory
Instead of creating temporarily files in the destination directory, create them in the
specified temporary directory. If this directory is on a different filesystem, that will
require moving the file rather than renaming it into place, and is therefore not atomic.
--timeout=seconds
Set the I/O timeout in seconds. Exit if no data was transferred for the specified time.
The default is 0, which means no timeout.
-t, --times
Set destination file and directory modification time to match the source when it is updated or created.
-u, --update
Skip existing files on the destination that have a modification time newer than the source file.
-v, --verbose
Increase verbosity. Specify once for files being transferred, twice for specific status,
thrice for per-file transfer information, and four times for per-file breakdowns.
-x, --one-file-system
Do not cross filesystem boundaries. If this option is repeated, all mount point directories from
the copy are omitted. Otherwise, it includes an empty directory at each mount point it encounters.
-V, --version
Print version and exit.
-W, --whole-file
Copy the entire file rather than using the rsync incremental algorithm.
This option may be faster, especially if the network link is faster than the disk.
--only-write-batch=file
Prepare a batch file and write it to file. With this option, the batch file is written without
updating the destination. See the below --write-batch option for a description of a batch file.
--write-batch=file
Prepare a batch file and write it to file. A batch file is composed of a small heading
describing the transfer parameters negotiated, followed by a raw dump of the data transmitted by
the sender. When used with --read-batch on the other side, the transfer is simply replayed from
the batch file against the application's reeceiver, and the destination tree is updated accordingly.
Batch files are intended to reproduce an update to a destination tree to many other identical
trees without needing to establish a direct connection between them. This mechanism also
avoids having to perform many of the intermediate steps required for a transfer, such as
receiver-side checksums and blocking.
A remote source or directory has the syntax host:path for connecting via ssh(1), or rsync://host/path or
host::path for connecting to a remote daemon. Subsequent to the first remote source,
the host may be dropped to become just :path or ::path.
For connecting to a remote daemon with rsync://host or host::path, the first path component is interpreted
as a "module": host::module/path. This only applies to the first source invocation;
subsequent to that, the module should not be specified.
By default, new destination files and directories are given the current time and the source file
permissions. Updated files retain their existing permissions. It is an error if updated files
have their file types change (e.g., updating a directory with a file).
At this time, source may only consist of regular files, directories (only with -r), or symbolic links
(only with -l). The destination directory must be a directory and is created if not found.
openrsync also supports a --daemon mode, which may be run either standalone or may be invoked by,
e.g., inetd(8) or similar services that hand a socket off to an external program for handling.
Daemon options that are shared with the non-daemon mode of openrsync behave as described above.
Options specific to daemon mode are as follows:
--config=configfile
Load daemon configuration from the named configfile instead of the default location.
By default, openrsync will look for its configuration at /etc/rsyncd.conf.
See rsyncd.conf(5) for details of the format of this file.
--no-detach
Run the openrsync daemon in the foreground, instead of the background.
Note that the openrsync daemon mode will log to syslog(3) by default unless --log-file is specified,
regardless of whether --no-detach has been specified to run in the foreground or not.
PATTERNS AND RULES
The -f, --include, --include-from, --exclude, and --exclude-from options may be used to load a filter
rule or a set of filter rules. A single filter rule consists of a type, an optional set
of modifiers, and a pattern. Each type has a short name and a long name.
These will be described in more depth shortly.
A filter file is a set of rules, one per line. Comments are accepted, starting with a ‘#’.
Empty lines are ignored.
Each rule is of the following form:
TYPE[,MODIFIERS] PATTERN
If the short name is used, then the comma separating the modifiers from the rule type is optional.
The delimiter between the type/modifiers and the pattern may also be an underbar instead of a space.
The following rule types are supported:
LONG NAME SHORT NAME DESCRIPTION
exclude - Exclude a file from the transfer
include + Include a file from the transfer
merge . Merge rules in from a file
dir-merge : Merge rules in from a per-directory file
hide H Hide a file from the transfer
show S “not hide a file from the transfer”
protect P Protect a file from deletion
risk R “not protect a file from deletion”
clear ! Clear the current filter list
The following rule modifiers are supported for the “exclude” and “include” rule types:
MODIFIER DESCRIPTION
/ Match against the absolute pathname of the entry
! Take effect if the pattern does not match the entry
C Insert the global CVS exclusions
s Marks a rule as sender-side only
r Marks a rule as receiver-side only
p Marks a rule as perishable (do not prevent removal of a directory)
The above modifiers will be ignored if applied to other rule types, with the exception of “merge” and
“dir-merge” rules. See the Merge Rules section for more details of the semantics.
Include and Exclude Rules
The six basic types of include and exclude rules briefly described above are “exclude”, “include”,
“hide”, “show”, “protect”, “risk”.
The “hide” and “show” types are sender-side versions of the “exclude” and “include” rules, while the
“protect” and “risk” types are their receiver-side equivalents.
Each of these rules take a pattern that is typically matched against the basename of a transfer
candidate's name. A trailing ‘/’ in the pattern indicates that the entry should only match a
directory name, while a leading ‘/’ indicates that the pattern is anchored to the beginning of
the transfer path. The beginning of the transfer path is either the root of the transfer, or
the directory containing a dir-merge file if the rule in question comes from a dir-merge file.
A ‘/’ at any other position, or a “**” in the pattern, will match against the full path to the
transfer entry beginning at the root of the transfer.
Patterns may contain any of the following wildcards.
WILDCARD DESCRIPTION
? Matches any character, except ‘/’
* Matches zero or more characters, except ‘/’
** Matches zero or more characters
[ Character class, as in POSIX regular expressions
/*** Matches a directory and all of its contents
Backslashes may be used to escape one of the above wildcard characters, but is ordinary when
appearing before any other character.
Note that exclude rules with the “C” modifier applied do not take a pattern.
Merge Rules
The merge rules, “merge” and “dir-merge”, are another way to insert a filter rule file.
“merge” rules are evaluated once as soon as they are processed, and the rules read in are
inserted at the same position as the merge file. “dir-merge” rules are evaluated as openrsync
progresses through the file list, searching each directory encountered for the file named in
the rule's pattern.
If a “dir-merge” rule appears before a “clear” rule, it will not be processed at all.
“dir-merge” rules are inserted into their own chain of rules, rather than directly into the global
ruleset. “clear” rules appearing in a dir-merged file do not affect the global ruleset.
As we find dir-merged files in the transfer, their rules are prepended to their dir-merge chain
so that a deeper directory's rules take precedence over its parent's rules.
When one of the above exclude/include modifiers are applied to “merge” or “dir-merge” rule,
those modifiers are applied to the exclude/include rules within the file.
The following modifiers may additionally be specified for merge rules:
MODIFIER DESCRIPTION
- All rules within are exclude rules
+ All rules within are include rules
C File processing should assume CVS-compatible parsing
e Exclude the file's name from the transfer
n Rules are not inherited by subdirectories
w Rules are word-split instead of line-split
The CVS-compatible modifier implies the ‘-’, ‘n’ and ‘w’ modifiers.
If a filename is not supplied with it, then “.cvsignore” is used.
The following environment variables affect execution of openrsync:
LOGNAME This variable may also hold the username to use when connecting to an rsync daemon. If LOGNAME is not set, then “nobody” will be used. USER This variable holds the username to use when connecting to an rsync daemon. If USER is not set, then LOGNAME will be used. RSYNC_RSH This variable specifies the remote shell to use for remote connections. The default remote shell is ssh(1) if neither RSYNC_RSH nor --rsh are specified. RSYNC_PASSWORD This variable specifies the password to use when connecting to an rsync daemon. It will be ignored if the --password-file option is specified and passes the mode and owner check described above in the option's description. On many systems, environment variables are readable by other processes and should be considered insecure. Please prefer a password file instead.
The openrsync utility exits 0 on success, 1 if an error occurs, or 2 if the remote protocol version is older than the local protocol version.
A common invocation of openrsync is for archiving from a remote host to the local computer:
% openrsync -av --delete remote:rpath /local/path
This will update the contents of /local/path/rpath with those on the remote server.
Switching remote and local wil update the remote contents instead:
% openrsync -av --delete /local/path remote:rpath
All examples use -t so that destination files inherit the source time.
If not changed, subsequent invocations of openrsync will then consider the file up to date
and not transfer block hashes.
To update the out-of-date remote files host:dest/bar and host:dest/baz with the local ../src/bar
and ../src/baz:
% openrsync -t ../src/bar ../src/baz host:dest
To update the out-of-date local files bar and baz with the remote files host:src/bar
and host:src/baz:
% openrsync -t host:src/bar :src/baz .
To update the out-of-date local files ../dest/bar and ../dest/baz with bar and baz:
% openrsync -t bar baz ../dest
To update the out-of-date remote files in host:dest on a remote host running openrsync with
the local host running rsync(1):
% rsync --rsync-path openrsync -t ../dest/* host:dest
