If it was a normal shell, it ought to have been rm -rf ${foo}/${bar} This is EXACTLY why I start all my shell scripts with set -eu The e means stop on an unexpected non-zero return code. The u means that referenceing an unset variable is an error. --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
