dit(bf(-a, --archive)) This is equivalent to -rlptgoD. It is a quick
way of saying you want recursion and want to preserve almost
destination file already exists and has a date later than the source
file.
+In the currently implementation, a difference of file format is always
+considered to be important enough for an update, no matter what date
+is on the objects. In other words, if the source has a directory or a
+symlink where the destination has a file, the transfer would occur
+regardless of the timestamps. This might change in the future (feel
+free to comment on this on the mailing list if you have an opinion).

dit(bf(-l, --links)) When symlinks are encountered, recreate the
symlink on the destination.
The exclude list is initialized to:
-quote(RCS/ SCCS/ CVS/ .svn/ CVS.adm RCSLOG cvslog.* tags TAGS .make.state
-.nse_depinfo *~ #* .#* ,* *.old *.bak *.BAK *.orig *.rej .del-*

dit(bf(--exclude=PATTERN)) This option allows you to selectively exclude
certain files from the list of files to be transferred. This is most
dit(bf(-0, --from0)) This tells rsync that the filenames it reads from a
file are terminated by a null ('\0') character, not a NL, CR, or CR+LF.
This affects --exclude-from, --include-from, and --files-from.
+It does not affect --cvs-exclude (since all names read from a .cvsignore
+file are split on whitespace).
dit(bf(-T, --temp-dir=DIR)) This option instructs rsync to use DIR as a
scratch directory when creating temporary copies of the files
linked.
Like bf(--compare-dest) if DIR is a relative path, it is relative
to the destination directory (which changes in a recursive transfer).
+An example:
+
+verb(
+ rsync -av --link-dest=$PWD/prior_dir host:src_dir/ new_dir/

dit(bf(-z, --compress)) With this option, rsync compresses any data from
the files that it sends to the destination machine. This

+/- pattern: /me/foo/bar
+/- pattern: /you/bar/baz
Target file: /dest/me/foo/bar
Target file: /dest/you/bar/baz
Example cmd: rsync -a /home/me/ /home/you/ /dest
- Source root: /home/me (due to trailing /)
- Source root: /home/you (ditto)
+/- pattern: /foo/bar (note missing "me")
+/- pattern: /bar/baz (note missing "you")

dit(bf(USER) or bf(LOGNAME)) The USER or LOGNAME environment variables
are used to determine the default username sent to an rsync server.
-If neither is set, the username defaults to "guest".
+If neither is set, the username defaults to "nobody".
dit(bf(HOME)) The HOME environment variable is used to find the user's
default .cvsignore file.
