you'd better modify here as the follow: [ -x "$path" ] || exit 0 . "$path" Here is the reason: looks `[ -x .. ] && ..` is the last line of this file. so the return code of last line of a script will be the execute code of this script. return code of `[ -x .. ] && ..` will be 1 if $path is not exist or not have execute permission. yuchuan@crystal ~% [ -x 123 ] && echo 123; echo $? 1 so if you have set -e in script, this will cause the exit of program. -------- Thanks Yu Chuan
