For that exact example... why you bother at all? $( ) opens a subshell and cd's in subshells don't interact with parent shell so you could simply write: OLD_VER=$(cd /boot; ls kernel-* | sort | head -1) or OLD_VER=`cd /boot; ls kernel-* | sort | head -1` if you want to be more compatible. Or am I missing a point? HTH, kind regards, Frank. -- Sigmentation fault -- [EMAIL PROTECTED] mailing list
