Definition:
The command to ignore the HUP (hangup) signal.
It prevents the process from exiting when the terminal or ssh session is closed.
How to use it
Start a process
- In the terminal:
- cd to the directory you'd like to start the process in.
- Run:
nohup [commandYoudLikeToKeepRunningAfterClosed] > /dev/null 2>&1 & echo $! > process.pid- This will start the process, and save a "process.pid" (process id number) file to the directory
- This is so that your filesystem has a record of which process is running, for use later.
Stop a process
- In the terminal:
- cd to the directory that the applicable process was started in.
- Run:
kill -9 `cat ./process.pid`- This will read the "process.pid" file, and use the value previously saved to kill that process.
