A common problem for server administrators is starting a command that takes hours to complete shortly before leaving the office and heading home.
Here are a few commands that will help you leave your computer while allowing the running command to finish:
1. To stop the currently running command, press Ctrl+Z.
2. To move the stopped process to the background, execute the command: bg
3. To ensure the command continues running after you close the SSH session, execute the command: disown -h
4. Exit the SSH session and go home; the process will finish in the background
