fg command in Linux
The Linux fg command is used to bring a background process to the foreground. It allows you to resume and manage a stopped job, making it the active one in your terminal session. By specifying a job number or the command name, you can easily bring the desired process back to the foreground. This command is handy when you have multiple processes running in the background and need to interact with a specific one without starting a new terminal session. With the fg command, you can conveniently control and monitor processes in your Linux system.
