![]() ![]() ![]() Pkill is used to kill processes according to an extended regular expression. If you want something where you don't need to know the exact name try pkill (below). Unfortunately you need to get the name exactly right for killall to work, you would need to use “mozilla-bin” to kill the mozilla browser. Would kill anything named “mozilla” and prompt you before each kill and report whether the kill was successful or not. Pkill - a little like a killall with regular expressions: pkill is another command that allows processes to be killed but does so using regular expressions. Use ps or pstree to find out the process id's (pid's), or use jobs to find out id's. To kill processes on your system, you will need their pid's or id's. Top also provides an updated display, it has many options that make it fully customisable, refer to the manual or info page for details. To list processes id's and names type: pgrep -l process_name topĭisplays the 'top' (as in CPU usage) processes, provides more detail than ps. If you are unfamiliar with the $( ) part of this command, please refer to the Section called Performing more than one command in Chapter 6. Note that this is the same as using pkill (see below). This would kill any process name that starts with mozilla. Normally pgrep will only return the pid number this way you can use it with other commands. Use the -l option to list the name of the process as well and the -u option to search via a particular user(s). This command is useful for finding the process id of a particular process when you know part of its name. This would list all processes and their id's. forest - this makes it easier to see the process hierarchy, which will give you an indication of how the various processes on your system interrelate (although you should also try pstree).įor example to list all running processes with additional information, simply type: ps -aux pstreeĭisplays the processes in the form of a tree structure (similar to how tree does it for directories). l - display different information including UID and nice value. x - list processes without controlling terminals. u - list more information including user names, %cpu usage, and %mem usage et cetera. aux - list all running processes (by all users with some information). With no options, ps will list processes that belong to the current user and have a controlling terminal. Will give you a list of the processes running on your system. ![]()
