-As a special case, if a remote source is specified without a destination,
-the remote files are listed in an output format similar to "ls -l".

As expected, if neither the source or destination path specify a remote
host, the copy occurs locally (see also the bf(--list-only) option).

-dit(bf(-c, --checksum)) This forces the sender to checksum every file using

-scan). The receiver then checksums every existing file that has the same

+dit(bf(-c, --checksum)) This forces the sender to checksum em(every)
+regular file using a 128-bit MD4 checksum. It does this during the initial
+file-system scan as it builds the list of all available files. The receiver
+then checksums its version of each file (if it exists and it has the same

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
dit(bf(--list-only)) This option will cause the source files to be listed
instead of transferred. This option is inferred if there is no destination
-specified, so you don't usually need to use it explicitly. However, it can
-come in handy for a user that wants to avoid the "bf(-r --exclude='/*/*')"
-options that rsync might use as a compatibility kluge when generating a
-non-recursive listing, or to list the files that are involved in a local

-must specify this option explicitly and still include a destination).

dit(bf(--bwlimit=KBPS)) This option allows you to specify a maximum
transfer rate in kilobytes per second. This option is most effective when
