This compares the output of the "cd" command against "0", numerically. That's probably not what you want. You probably want to compare the exit code of the "cd" command against "0", numerically. Something like: cd "$1" if [ $? -ne 0 ]; then ... fi or simply: if ! cd "$1"; then ... fi -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
