manpagesynopsis()
--super receiver attempts super-user activities
--fake-super store/recover privileged attrs using xattrs
-S, --sparse handle sparse files efficiently
- -n, --dry-run show what would have been transferred
+ -n, --dry-run perform a trial run with no changes made
-W, --whole-file copy files whole (without rsync algorithm)
-x, --one-file-system don't cross filesystem boundaries
-B, --block-size=SIZE force a fixed checksum block-size
--delay-updates put all updated files into place at end
-m, --prune-empty-dirs prune empty directory chains from file-list
--numeric-ids don't map uid/gid values by user/group name
- --timeout=TIME set I/O timeout in seconds
+ --timeout=SECONDS set I/O timeout in seconds
+ --contimeout=SECONDS set daemon connection timeout in seconds
-I, --ignore-times don't skip files that match size and time
--size-only skip files that match in size
--modify-window=NUM compare mod-times with reduced accuracy
filesystem. It doesn't seem to handle seeks over null regions
correctly and ends up corrupting the files.
-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(-n, --dry-run)) This makes rsync perform a trial run that doesn't
+make any changes (and produces mostly the same output as a real run). It
+is most commonly used in combination with the bf(-v, --verbose) and/or
+bf(-i, --itemize-changes) options to see what an rsync command is going
+to do before one actually runs it.
+
+The output of bf(--itemize-changes) is supposed to be exactly the same on a
+dry run and a subsequent real run (barring intentional trickery and system
+call failures); if it isn't, that's a bug. Other output is the same to the
+extent practical, but may differ in some areas. Notably, a dry run does not
+send the actual data for file transfers, so bf(--progress) has no effect,
+the "bytes sent", "bytes received", "literal data", and "matched data"
+statistics are too small, and the "speedup" value is equivalent to a run
+where no file transfers are needed.
dit(bf(-W, --whole-file)) With this option the delta transfer algorithm
is not used and the whole file is sent as-is instead. The transfer may be
timeout in seconds. If no data is transferred for the specified time
then rsync will exit. The default is 0, which means no timeout.
+dit(bf(--contimeout)) This option allows you to set the amount of time
+that rsync will wait for its connection to an rsync daemon to succeed.
+If the timeout is reached, rsync exits with an error.
+
dit(bf(--address)) By default rsync will bind to the wildcard address when
connecting to an rsync daemon. The bf(--address) option allows you to
specify a specific IP address (or hostname) to bind to. See also this
dit(bf(24)) Partial transfer due to vanished source files
dit(bf(25)) The --max-delete limit stopped deletions
dit(bf(30)) Timeout in data send/receive
+dit(bf(35)) Timeout waiting for daemon connection
