HowTo Keep Processes Running After Logging Out Using: "setsid"

HowTo Set The Session ID (SID) and Process Group ID (PGID)

The "setsid" command allows one to set a new "Session ID" (SID) and "Process Group ID" (PGID) for a given command. This can be quite useful when logging out from a shell environment and keeping a process up and running. Since the process is running in an entirely different "session", it should not be effected by logging out and terminating the shell.

Command: "setsig"    Example: Keep The "Find" Command Running After Logging Out.

[root@probe tmp]# setsid find / -name "rmsession.log" >| "/tmp/findresults" &

[root@probe tmp]# exit

One can also use the "nohup", "disown" and "screen" commands to provide similar results.
