Start process independent from TERMINAL (or also with PPID 1)
Hi *,
please, I need fast tip (help). I have a process starting through /etc/rc3.d/xxxx script. However, sometimes (mostly because of testing reasons) I need to stop the process, change something and then start it again. But:
1) when I start it in terminal, the process dies when I leave the terminal.
2) I tried the command :
nohup <script_file> &
but it's not working correctly. The best will be if there is a possibility to start the process INDEPENDENT from terminal (so when I close it it will not die) and that the process has PPID 1 (like it was started from rd3.d).
is there some way to do this ?
thanks you all for fast reply and help
best regards
Marek

ps
PS(1) General Commands Manual PS(1) NAME
ps - process status SYNOPSIS
ps [-alxU] [kernel mm fs] OPTIONS
-a Print all processes with controlling terminals -l Give long listing -x Include processes without a terminal EXAMPLES
ps -axl # Print all processes and tasks in long format DESCRIPTION
Ps prints the status of active processes. Normally only the caller's own processes are listed in short format (the PID, TTY, TIME and CMD fields as explained below). The long listing contains: F Kernel flags: 001: free slot 002: no memory map 004: sending; 010: receiving 020: inform on pending signals 040: pending signals 100: being traced. S State: R: runnable W: waiting (on a message) S: sleeping (i.e.,suspended on MM or FS) Z: zombie T: stopped UID, PID, PPID, PGRP The user, process, parent process and process group ID's. SZ Size of the process in kilobytes. RECV Process/task on which a receiving process is waiting or sleeping. TTY Controlling tty for the process. TIME Process' cumulative (user + system) execution time. CMD Command line arguments of the process. The files /dev/{mem,kmem} are used to read the system tables and command line arguments from. Terminal names in /dev are used to generate the mnemonic names in the TTY column, so ps is independent of terminal naming conventions. PS(1)
