But that is exactly what we told cp to do with --remove-destination. And strictly speaking, it is also what POSIX requires for 'mv -f', but as you can see: $ mkdir a b c $ echo 1 > a/f $ echo 2 > b/f $ mv -fv a/f b/f c `a/f' -> `c/f' mv: will not overwrite just-created `c/f' with `b/f' > Doesn't POSIX require this to succeed? Only if it also requires the same for mv and cp. And Jim Meyering has a pending aardvark with the Austin Group to make sure the next revision of POSIX allows GNU's behavior: it is nice to rely on the GNU assumption that cp, ln, and mv should never be able to lose user data due to collisions in the destination. - -- Don't work too hard, make some time for fun as well!
