nohup

In Linux, the nohup command stands for "no hang up." It allows you to run commands or processes that continue running even after you log out of the terminal or close the session.

nohup command > output.txt &

This will redirect the output of the command to the file output.txt

If you want to keep your processes/jobs running, precede the command with nohup as shown below. The jobs will still continue running in the shell and will not get killed upon exiting the shell or terminal. nohup ./hello.sh
