how to find the caller of the script

[rubash]

i want away to know which file called the script


i have a bash shell script , a php file calls this script .
i need to make sure the the file is always called from this php
and no other way
please advice.

Yeah, just an idea:

var_arithmetic.sh:

#! /bin/bash -x

caller.sh

caller.sh:

#! /bin/bash -x

pstree -A | grep `basename $0`

[Lost_scrib@localhost ~]$ var_arithmetic.sh
output: |-gnome-terminal-+-bash---var_arithmetic.---caller.sh---pstree

[rubash]

Thanks Lost_scrib
i used this way , but i was using redhat 4,so the option A was not exist , so i didn't reach the orginal file


i applied the way u did on fedora , it works .
Appreciated
