nohup invokes a utility immune to hangups.
On one of my servers I have been using
nohup for quite some time now, because I knew I had to use it to, let's say, get some things done. Nevertheless, today I learned what
nohup really does.
If you execute a job in Unix, the process will get killed as soon as you logout from the session. This can be avoided by using
nohup keeps the process running—even if you logout from the session.
nohup stand for no hang up.
