Ksh does some pre-parsing on the argument to 'cd'. It removes from the argument all the '..' and the name before the '..' (for optimization, I guess): cd _not_a_directory/../_junk_/.. has no effect, even though 2 directories in the argument don't exist. The problem is that if you type: cd _valid_CDPATH_directory/.. it has no effect either and I think that's a bug. $ echo $CDPATH :/a/b/c $ cd /a/b/c/d $ pwd /a/b/c/d $ cd / $ ls d d: No such file or directory $ cd d/.. $ pwd / This works with /bin/sh (the shell would put me in /a/b/c) and I didn't find anything in the man page that would mention this as a 'feature'.

This was removed; it is not present in ksh88f: $ cd $ mkdir -p $HOME/x/y $ CDPATH=:$HOME/x $ cd y/.. $ pwd /usr6/lvc/x Ksh will do a CDPATH search even if there are /'s in the path given to cd and it will not do any sort of pre-parsing now. -- Larry Cipriani, att!cbvox!lvc or lvc@cbvox.att.com "Fight fire with fire, I always say" -- Bugs Bunny
