Suppose that I want to run a Java program so I would type

java myProgram

and then suppose that it prints some output to the screen but takes a few hours to finish running. If I want to keep working on the same terminal while it runs, what is the command that I should use? I tried & at the end and it did not seem to work.

Just add a & after the command. This will make the command run on the background.

Notice that you will still get the output of it, so you may want to redirect the output to /dev/null or to some configuration file.

E.g. in order to redirect both stdout and stderr:

java myProgram > /dev/null 2>&1 &
