jobs Linux command
The Linux jobs command is a useful tool for managing background jobs within a terminal session. This command allows users to monitor, control, and manipulate processes that are running in the background. By using the jobs command, users can view a list of all active background jobs, along with their respective job IDs. This makes it easier to keep track of multiple processes running simultaneously and allows users to bring jobs to the foreground or background, as needed. Additionally, the jobs command provides options for manipulating the status of jobs, such as suspending or resuming them. This can help users efficiently manage their workflow and ensure that all processes are running smoothly.
