-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

dit(bf(--version)) print the rsync version number and exit.
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:

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.
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(--ignore-existing)) This tells rsync to skip updating files that
+already exist on the destination. See also bf(--ignore-non-existing).
-dit(bf(--ignore-existing))
-This tells rsync not to update files that already exist on
-the destination.
+dit(bf(--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). Note that in older
+versions of rsync, this option was named bf(--existing), so this older
+name is still accepted as an alias.
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
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.
because it takes advantage of the implicit information in the matching data
blocks that are not explicitly sent over the connection.
+dit(bf(--compress-level=NUM)) Explicitly set the compression level to use
+(see bf(--compress)) instead of letting it default. If NUM is non-zero,
+the bf(--compress) option is implied.
+
dit(bf(--numeric-ids)) With this option rsync will transfer numeric group
and user IDs rather than using user and group names and mapping them
at both ends.
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
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.)
-Conflicts with bf(--inplace).
+each file's destination directory, but if you've specified the
+bf(--partial-dir) option, that directory will be used instead.
+Conflicts with bf(--inplace) and bf(--append).
This option uses more memory on the receiving side (one bit per file
transferred) and also requires enough free disk space on the receiving
