![]() ![]() This page explained various Linux commands to find out what processes are running in the background. Similarly one can use an enhanced version of the top like atop or htop. ![]() Run it as follows and look for STAT (s) column. The top command displays Linux processes in real-time. # ps T Display Linux processes without controlling ttys # ps r List all processes on this current terminal # ps -eo pid,user,stat,comm | grep nginx How do I list only running processes on Linux? You can combine ps with grep command command as follows: Use the following command to list Linux processes along with pid, user name, stat as follows: Command/īackground process (interruptible sleep and a session leader)īackground process (interruptible sleep+a session leader and multi-threaded app)īackground process (interruptible sleep and a session leader and is in foreground group) Is my Linux process running in the foreground or background?īased upon the above tables, one can determine if Linux process in background or foreground or running and so on. Is multi-threaded (using CLONE_THREAD, like NPTL pthreads do) Has pages locked into memory (for real-time and custom IO) Additional characters may be displayed as follows too: Process STATE code Therefore, you cannot kill “D” state processes as they are uninterruptible. On the other hand, processes in a “D” or uninterruptible sleep state are usually waiting on I/O. ![]() The interruptible sleep means the process can be terminated or killed with the help of kill command. Typically process in “interruptible sleep” are running in the background and shows a “ S” on processes STAT column. Paging (not valid since the 2.6.xx kernel)ĭefunct (“zombie”) process, terminated but not reaped by its parent Interruptible sleep (waiting for an event to complete) The STAT coloum gives us the state of a Linux process: Process STATE code The process name itself displayed in the last column. For example, the daemon user started the atd process. The first column shows the user name who started the foreground or background processes on Linux system. ![]() List all running processes on Linux using ps command Understanding ps command outputs ![]()
