you'd better modify here as the follow: [ -x "$path" ] || exit 0 . "$path"

good Thanks, Yinsi

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
