== Forking ==

If a command ends in `&`, it is pushed to the background as a child process. The shell does not await that child process returning, and can exit immediately.

These child processes are called '''jobs''', and they are managed with three [[Shell/BuiltinCommands|builtins]]:

 * `bg`, which moves a job to the background
 * `fg`, which resumes a job in the foreground
 * `jobs`, which lists running jobs

Note that the `kill`, `disown`, and `wait` builtins work on both processes and jobs.

----



== Pushing to Background ==

With the keyboard sequence of Control+Z, a running process (such as [[Emacs|emacs]] or [[Vim|vi]]) can be pushed to the background. Functionally this is the same as forking. So similarly, to resume work in the editor, use `fg`.
