See also the GNU-specific mv -t two one To move one into two. For the reverse: force a move-to as opposed to a move-into, another GNU-specific option: mv -T one two if two is a directory, you'll get an error. If two is a symlink (to directory or other), one is renamed to two (and the symlink is gone). FreeBSD mv has: mv -h one two To do a move-to instead of move-into when "two" is a symlink to a directory. -- Stephane
