fg [PID]
The fg builtin brings the specified :ref:job <syntax-job-control> to the foreground, resuming it if it is stopped.
While a foreground job is executed, fish is suspended.
If no job is specified, the last job to be used is put in the foreground.
If PID is specified, the job containing a process with the specified process ID is put in the foreground.
For compatibility with other shells, job expansion syntax is supported for fg. A PID of the format %1 will foreground job 1.
Job numbers can be seen in the output of :doc:jobs <jobs>.
The --help or -h option displays help about using this command.
fg will put the last job in the foreground.
fg %3 will put job 3 into the foreground.
