fg

fg is used to bring a suspended job to the foreground. In Linux, a job refers to a process running in the background. When a process is running in the foreground, the terminal is blocked until the process completes. However, if a process is running in the background, the terminal is free to accept other commands.

Basic Syntax

The basic syntax of the fg command is:

fg [job_spec]

Here, job_spec refers to the job ID or job name of the suspended process that needs to be brought to the foreground. If no job_spec is specified, the most recently suspended job is brought to the foreground.

Useful Examples

• fg: This brings the most recently suspended job to the foreground.
• fg %1: This brings the job with job ID 1 to the foreground.
• fg top: This brings the job with the name top to the foreground.
