Explanation
The bg command is used to resume a suspended command in the background, allowing it to run without user interaction. The command takes a job ID as an argument, which can be obtained by using the jobs command.
Alternatively, if no job ID is specified, bg will resume the most recently suspended job. The bg command is part of the job control features of the Linux shell, which allow users to manage multiple processes running in the same terminal. References:
