like r2evans said ${PPID} is the right direction:

that is what you want:

echo "i was called from: $(ps -p $PPID -o command | sed '1d')"

see man ps, man sed and man bash for explanations. The PPID is explained in man bash.

If I call my script from the testparent script, it looks like this:

$ ./testparent arg1 arg2
i was called from: /bin/bash ./testparent arg1 arg2
