+they point to (the referent) is copied, rather than the symlink. In older
+versions of rsync, this option also had the side-effect of telling the

+modern rsync such as this one, you'll need to specify --keep-dirlinks (-K)
+to get this extra behavior. The only exception is when sending files to

dit(bf(--copy-unsafe-links)) This tells rsync to copy the referent of

--partial option tells rsync to keep the partial file which should
make a subsequent transfer of the rest of the file much faster.
+dit(bf(--partial-dir=DIR)) Turns on --partial mode, but tells rsync to
+put a partially transferred file into DIR instead of writing out the
+file to the destination dir. Rsync will also use a file found in this
+dir as data to speed up the transfer (i.e. when you redo the send after
+rsync creates a partial file) and delete such a file after it has served
+its purpose.
+
+Rsync will create the dir if it is missing (just the last dir -- not the
+whole path). This makes it easy to use a relative path (such as
+"--partial-dir=.rsync-partial") to have rsync create the partial-directory
+in the destination file's directory (rsync will also try to remove the DIR
+if a partial file was found to exist at the start of the transfer and the
+DIR was specified as a relative path).
+
+If you are deleting files on the destination and your partial-dir is
+inside the destination hierarchy, make sure you specify an exclude to
+prevent the partial file from being deleted (it could get deleted at the
+end of the transfer when using --delete-after, or at the beginning of the
+transfer when using --delete). E.g. "--exclude=.rsync-partial/".
+
+IMPORTANT: the --partial-dir should not be writable by other users to
+avoid a security risk. E.g. AVOID "/tmp".

dit(bf(--progress)) This option tells rsync to print information
showing the progress of the transfer. This gives a bored user
something to watch.

Batch mode can be used to apply the same set of updates to many
identical systems. Suppose one has a tree which is replicated on a

batch update fileset. When a difference between the destination trees

+appears to be up-to-date already) or the file-update may be attempted
+and then, if the file fails to verify, the update discarded with an
+error. This means that it should be safe to re-run a read-batch operation
+if the command got updated. If you wish to force the batched-update to
+always be attempted regardless of the file's size and date, use the -I
+option. If an error occurs, the destination tree will probably be in a
+partially updated state. In that case, rsync can
be used in its regular (non-batch) mode of operation to fix up the
destination tree.
The --dry-run (-n) option does not work in batch mode and yields a runtime
error.
