What Operating System and version you you have? (uname -a).

Your code :!ps -f is showing the commands firing at that time which is present inside the sh file but no sh file displaying which is running in backend.
The "ps -f" shows all processes running in foreground or background which were started from that terminal.
What does "... running in backend" mean?

Can you show an example of what you type and what actually happens?

In HP-UX 11i the permissions on "fuser" are 644 bin bin. Also there is no "ptree" command.

This is quite unfortunate. Is it a bug on your system or by design ?

Can you double check that. It seems it has been documented on HP-UX since at least 1993 and the open poster has ptree available.

I stand corrected. Looks like "ptree" "pgrep" and "pkill" were finally available in HP-UX 11.23. They were missing in 11.00 and 11.11 and I wrote my own scripts with the functionality I missed.

The "fuser" on HP-UX is weird because part of the output is directed to STDERR. This makes the output fiddly to process in Shell. There seems to be no rational reason for the permissions but they are standard issue.
To get just the Process Id's:
Code:
/usr/sbin/fuser filename 2>/dev/null

I suspect from having used HP-UX for a while now that the reason
part of the outptut goes to STDERR instead of all to STDOUT or STDERR is so you can do as Methyl points out:

Code:
/usr/sbin/fuser filename 2>/dev/null

And get just the PID.

I still remember way back when trying to get fuser output through a pipe and failing miserably! Smilie

This useful feature isn't HP-UX specific. There is no need to filter out the pids thanks to it. As long as ptree is available and accept a list of pids, the command I suggested should work just fine precisely because the stdout/stderr split:
Code:
 ptree $(pfiles nohup.out)
