Controlling process

Is there any software (or UNIX/Linux command) that I can use to find out what process is attaching to another process and is controlling it?

I have a process that is running on SLES10 SP3. This process output is altered to produce the wrong result. I am trying to find out the attach to the system.

Thx

Well, pstree leaps to mind, check it out. Even ps ought to get you most of what you want. Try something like:

Code:

---

ps -eo user,pid,ppid,cmd|grep YOUR_PROCESS_NAME

---

The 3rd column in the output is the pid of the parent process of each process. So you could then run another ps and grep for that pid, etc.
