The correct solution in this case is using basename, since it is a filepath problem. More generally, it's a split() problem. Only most generally is regexp appropriate. Even then, I would avoid POSTMATCH - while the expense is tolerable, it's still high. Better to actually match the string you want, and remember that.

$x =~ m|(?:[^/]/)*/(.*)};
print $1;
