[Help-bash] How to show the path of a bash script in $PATH?

[Peng Yu]

Hi,

`which` only shows the path if the command is an executable. What if a
bash script is in $PATH but it is just for `source` only (i.e., not
executable)? Is there an easy to find its path?

This can be done with `find` and a bit programming. But since bash is
able to resolve the path of a script for sourcing, I'd imagine there
might be a way to use this bash capability to directly get the path of
the script.
