Let us say you’re accessing an another system remotely via SSH. You want to run a command that takes a long time to finish and then exit the SSH session but leave the command running even if you’re no longer connected with the remote system. How do you do that?

Here I have given different 4 methods to keep a command running after you log out from an ssh session.
