How do I run a script in the background and leave it running when I log out? [duplicate]

Solution 1:

You want to use the program screen. Here is the man page for it, and here is a nice tutorial. It should do exactly what you want it to do - execute something in the background and be able to come back to it later.

Solution 2:

You can use:

nohup /path/to/script >output 2>&1 &

Solution 3:

You could start a screen session, start your job, and the disconnect from the screen session.

Later, you can reattach to your screen session to see if your job has completed.

Solution 4:

nohup

nohup - run a command immune to hangups, with output to a non-tty

— man nohup

Solution 5:

With bash:

my_program &
disown -h %1

Alter the number for your actual job number (see jobs builtin too)
