Oh, I was using an unreadable and unexecutable parent directory. If I try it with 0711... 0 ~/tmp/foo/bar$ sudo chmod 711 ../../foo 0 ~/tmp/foo/bar$ ls -ld ../../foo drwx--x--x 6 root wheel 204 Jul 13 16:02 ../../foo 0 ~/tmp/foo/bar$ whoami schwern 0 ~/tmp/foo/bar$ groups schwern staff appserverusr admin appserveradm perl 0 ~/tmp/foo/bar$ bleadperl -MFindBin -wle 'print $FindBin::Bin' pwd: : Permission denied 0 ~/tmp/foo/bar$ perl -MFindBin -wle 'print $FindBin::Bin' Use of uninitialized value in print at -e line 1. 0 ~/tmp/foo/bar$ perl -wle 'print `pwd`' pwd: : Permission denied 0 ~/tmp/foo/bar$ pwd /Users/schwern/tmp/foo/bar That last one works because its the shell's internal pwd using $PWD. -- Michael G Schwern [EMAIL PROTECTED] http://www.pobox.com/~schwern Ahh email, my old friend.
