These commands will place the first process in the background job queue into the foreground and the last process in the foreground job queue into the background. The commands fg and bg are useful for finding foreground and background processes in Linux. To kill a background process, use the command pkill and the process ID, or process name. The Importance Of Background Processes In Linuxīackground processes are necessary in Linux for many tasks, including sending and receiving emails.
If you leave the shell or exit the window manager, the process will keep running as long as no user interaction occurs. What Is Background Process In Linux?Ī Linux background process is a type of process that does not require the user to open the Shell or Window Manager.
