Others have posted a number of useful solutions to this sort of
problem. However all of those solutions require a deal of
forethought.
Suppose you've got a long running process hogging the foreground of
your shell, and you want to background it. All you need do is hit
Ctrl-Z to stop the process and then 'bg' to restart it in background.
If you've got a lot of jobs running concurrently in a shell you might
need to tell the shell which one to background, which you do by: 'bg
%n' -- 'n' is the job number, as returned by the 'jobs' shell built-in
command. Putting the process into the background like that is usually
enough to protect the process from being killed when you log out,
although different shells can behave differently in that respect.
Cheers,
Matthew
