While top is installed by default, you will need to install htop should you wish to use it. R: reverses the default list order (changes from descending to ascending order)Ī popular version of ‘top’ is htop. R: changes the priority of a process (nice values that are negative get a higher priority than positive numbers all processes begin with a value of 0)

#Bash command line ps ef full

Listing some processes in Linux can be brought about by pressing just one key (remember these are case sensitive):Ĭ: reveals the full path of a program (by default this is not the case) pressing c will return you to default if in full path viewĭ: changes refresh time (default refresh time is three seconds) $ top i: will not list processes in zombie state $ top p : lists the processes for a specific PID $ top u : lists processes for a specific user Zombie (Z): awaiting action from the parent process to officially complete process.Stopped (T): a paused process that is awaiting prompt to either continue (SIGCONT) or officially stop (SIGKILL).There are two types of Interruptible Sleep (S) and Uninterruptible Sleep (D) Sleeping (D): awaiting another process (an event) or resource to continue its process.

Running/Runnable (R): the former is currently active, but the latter is awaiting a slot so it can begin performing its process.Shift + p: list according to CPU use (default) You can choose whether to list processes according to how much CPU or memory is being used per process. To list processes using top, the command is $ top. It is this fact that adds a dynamic element to top commands because the list is adjusted according to the demands of your processes. Top commands are ideal if your goal is to list processes on Linux to identify which ones are using up the most resources. Change the format to a tree-based one with pstree. Perhaps the linear format is not effective. $ ps eF: in addition to the information above, using a capital ‘F’ will also produce RSS, the name of the processor running the process and the overall size of the process (SZ). $ ps ef: will produce processes that include the command that called up the process, PID, User Identification Number (UID), parent process identification number (PPID), and some information about start and run times. Check out the following commands that are the same in make-up, but will list different processes on Linux. $ ps x: identifies processes that usually run in the background and were started at boot time, because they have no controlling terminalĬommands (not just ps commands) are case sensitive.

$ ps u: adds other useful information, such as virtual memory size (VSZ), resident set size (RSS) and process identification number (PID) $ ps u OR $ ps ef | grep USERNAME: if you want to list processes on Linux for a specific user from a different shell

$ ps a: lists all processes on all shells of your server This information is static and limited, so you will need to expand the command to know more. $ ps: produces a list of the processes currently running on the specific shell (or account). It’s responsible for generating a snapshot of all running processes. The ps command is short for Process Statuses. First, well look at the ‘ps’ command and explain what you can learn from each process. Here are a few: the resources being used by a process the effect of your load demands on your overall system and memory demands. But there’s lots more that you can learn from listing processes on Linux. Listing the processes means you identify those active procedures running on your server.
