You want to know which program invoked script.sh? A ps listing will reveal the parent PID. It's possible for the parent to exit before the child does, though; then your process will show as orphaned.
Code:
ps wallx | { head -1; grep 'script\.sh'; }
The head is just to get the explanatory header as well; in a script, you don't want that. Example: Code:
vbvntv$ ps wallx | { head -1; grep to*tem ; }
F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND
