fg - run jobs in the foreground
fg [%job ...]
fg [job ...]
This command is a built-in command in the C shell and the Korn shell.
The fg(1) command brings the specified jobs (or, without arguments, the current job) into the foreground, continuing each if it is stopped. The job argument can be a number, a string, '', '%', '+' or '-' as described under the Jobs section in tcsh(1). See also the run-fg-editor editor command in tcsh(1).
The fg(1) command resumes the specified job(s) in the foreground. If no jobs are specified, %+ is assumed. This command is only available on systems on which job control is enabled. See the Job Control section in ksh(1) for more information.
