fg Command in Linux: Bring Background Processes to Foreground

The fg command in Linux does exactly the opposite of the bg command, bringing the task or background process to the foreground and attached to a terminal.

It also accepts a job number as a parameter.

In this example the find command is again placed in the background with Ctrl-Z and it receives the Job number 1:

$ find / -iname a* 2>/dev/null ^Z[1]+  Parado                  find / -iname a* 2> /dev/null

To see the programs running in the background, the jobs command can be executed:

$ jobs[1]+  Parado                  find / -iname a* 2> /dev/null

To bring the Job back to the foreground and connected to the terminal, just run fg. In this example, the Job number was passed as a parameter:

$ fg 1find / -iname a* 2> /dev/null
