Find line number of function call from sourcing file

Question

I\'m trying to find a way to find out what file and line number a function was called from. The function is in a library file which is being sourced by my script.

Answer 1

You are looking for caller it seems.

$ cat h.sh 
#! /bin/bash
function warn_me() {
  echo "$@"
  caller 
}
$ cat g.sh 
#!/bin/bash
source h.sh
warn_me "Error: You didn't do something"
$ . g.sh
Error: You didn't do something
3 g.sh
