Or, rsync may be used for this purpose, too.
Contrary to unison, rsync expects one to specify the direction
of the sync explicitly, which eliminates the necessity of
storing any ``state'' files for the media to be synchronized,
but otherwise these two seem quite close (though I find the
rsync configuration means more ``readable''.)
Like (note that the meaning of -u, -v, -a, -b and --suffix= is
basically the same as in cp(1) and mv (1)):
$ rsync -uvab --suffix=.~rsync~ --backup-dir=.rsync-backup \
--exclude=\*~ --exclude=.rsync-backup/ \
/media/flash/ \
"$HOME"/
(More complex inclusion (exclusion) patterns are available with
--filter=.)
