Let\u2019s find out what you can do with \u201ckillall\u201d. It\u2019s just like \u201ckill\u201d but with a lot more power in the pocket. It\u2019s a CLI tool. Caution is a must as a wrong command can completely render your system useless.<\/p>\n<p>\u201ckillall\u201d follows the following structure \u2013<\/p>\n<p>According to the man page of \u201ckillall\u201d, the tool sends a signal to the target processes. Without specifying the signal type, the default is SIGTERM. If \u201ckillall\u201d is able to kill at least 1 process matching the requirements, it returns a zero return code. You can\u2019t kill a \u201ckillall\u201d process.<\/p>\n<h3>Killing a process<\/h3>\n<p>This is the most basic usage of \u201ckillall\u201d command. All you have to do is just pass the name of the process.<\/p>\n<p>For example, I\u2019ve got GNOME Disks open, process name \u201cgnome-disks\u201d. For killing the process, run the following command \u2013<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/linuxhint.com\/wp-content\/uploads\/2018\/11\/1-35.png\" alt=\"\" width=\"1140\" height=\"560\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/linuxhint.com\/wp-content\/uploads\/2018\/11\/2-36.png\" alt=\"\" width=\"1140\" height=\"554\" \/><\/p>\n<h3>Asking for permission<\/h3>\n<p>When you\u2019re running \u201ckillall\u201d commands, there\u2019s a pretty good chance that you\u2019re about to kill something unintended.
