For running a process in the background.
Ctrl-C: Kill the process running in the foreground by sending the signal SIGINTCtrl-Z: Suspend the process running in the foreground by sending the signal SIGTSTPjobs: Display a list of the jobs with their statusfg: Move a background job into the foregroundbg: Resume suspended jobs by running them as background jobs
When used at the end of a command it will run the process in a subshell (in the background). It also does not wait for the process to end it returns a 0 status.
When a job runs in the background, its output is still displayed in the terminal. This occurs because the background process initiated by the & operator inherits the shell's stdout and stderr.
