$0 will always contain the file path, unless the script was started as: bash script.sh And there's no script.sh in the current directory (in which case sh/bash will have looked up script.sh in $PATH). So: #! /bin/sh - dir=$( cmd=$0 [ -e "$cmd" ] || cmd=$(command -v -- "$cmd") || exit dir=$(dirname -- "$cmd") cd -P -- "$dir" && pwd -P ) || exit # untested should give you the absolute path of the directory portion of the script path (unless that directory ends in newline characters). -- Stephane _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
