How do I fork a process that doesn't die when shell exits?

Sometimes I remotely connect to my Ubuntu using NX. I then run some jobs in the background, e.g.:

$ /path/to/script.pl &

However, when I log out, the jobs stop running.

How can I make them continue even after I log out?

Answer 1

I think another alternative would be to use screen.

Answer 2

The shell kills all processes in its process group when it ends, by sending SIGHUP.

If you run the bash shell, you can type disown to keep it running after you log out. This removes it from the list of processes it will send signals to.

Or you can launch the script with nohup, but then you have to remember this when you run the command. This tells your command to ignore the SIGHUP signal that the shell will send. This will work on any shell.

Answer 3

You can use nohup

nohup /path/to/script.pl &

Answer 4

See "Keep linux scripts running after you have closed a remote shell" for how to do this using the screen command.
