nohup

nohup runs background processes uninterruptedly even the remote SSH session goes offline.

nohup mycmd &

You can also lower the priority for the background process

nohup nice mycmd &

Output¶

The output will be in nohup.out by default. If you want to customize the output location, just redirect it:

nohup mycmd &> log.txt &

To monitor what is going on in nohup.out

tail -f nohup.out

You can kill the ongoing process by the process ID (PID).

ps -aux | grep mycmd
kill PID

Use sudo -b CMD

nohup sudo -b CMD

Use logrotate. Configure something like this in /etc/logrotate.conf

/etc/logrotate.conf

/path/to/nohup.out {
    size 1024k
    copytruncate
    rotate 100
    maxage 100
