Run a command that won't be killed when you log out.
When you log out or are otherwise disconnected, a hangup signal is sent to all your processes. Using nohup causes those signals to be ignored:
nohup myscript > myscript.out 2>&1 &
If you just do:
nohup myscript &
any output from "myscript" will be sent to "nohup.out" which will be created or appended to.
Make sure "myscript" doesn't read from standard input; that won't work without redirection:
nohup myscript < answers &
Note that you need "&" to put the command in background; nohup doesn't do that for you.
