The kill command will kill a single process at a time with the given process ID. If you know a process ID, you can kill it with the command: kill Send a specific signal to the process, rather than SIGTERM. Only kill the processes that match the pattern exactly. Only kill the processes that are owned by the selected user. Only kill the oldest of the processes that are discovered. Only kill the newest of the processes that are discovered. By default, pkill will send the SIGTERM signal. The pkill command is similar to the pgrep command, in that it will kill a process based on the process name, in addition to other qualifying factors. The killall -o 15m command will kill all processes that are older than 15 minutes, while the killall -y 15m command will kill all processes that are less than 15 minutes. Use this flag with a duration to kill all processes that have been running less than that amount of time. Use this flag with a duration to kill all processes that have been running more than that amount of time. In addition to killing processes based on name, the killall command can also be used to kill based on the age of the process, using the following commands: Report back on whether the process has been successfully killed. Only kill processes owned by a specific user. Ask for additional confirmation when killing the process. Ignore case when trying to find the process name. Find an exact match for the process name. Several options can be used with the killall command: The killall command can kill multiple processes with a single command. By default, it will send a SIGTERM signal. The killall command is used to kill processes by name. There are a few different methods of killing a process in Linux, depending on whether you know the name of the process running, the pid of the process, or just how long the process has been running. Step 3: Use Kill Command Options to Terminate a Process Also returns PIDs of shells that are running scripts. Omit certain PIDs (include the processes to omit after the flag). Only return PIDs within a single root directory. The pidof command is used to find the ID of a process, provided that you know the name of the process. The command pgrep -u root 'a*' returns processes owned by root that start with the letter “a”. The command pgrep -u root displays all processes owned by root. Only find processes that exactly match the given pattern. Only find processes that belong to a specific user. List both the process names and the PIDs. Here are the options that can be used with this command: The pattern is a regular expression, such as a*, where * would be a wildcard. This command will return processes based on specific selection criteria, which is known as the pattern. The Linux command pgrep is a more complex way of finding a process. The top command will reveal process IDs and users, in addition to the amount of memory and CPU power each process is using. To view a list of all currently running processes, use the command: top The top command is the easiest way to get a complete overview of the processes currently being run. It can be considered a gentler way of attempting to terminate a process.įor most purposes, SIGKILL will be the fastest and most effective method to terminate the process. SIGTERM – SIGTERM attempts to kill a process, but unlike SIGKILL it may be blocked or otherwise handled.If it does not work, the operating system has failed. It will always kill a process and will kill the process abruptly, generating a fatal error. SIGKILL – SIGKILL is the ultimate way of killing a process.There are multiple types of termination messages including: Killing a process sends a termination message to the given process. You can either add sudobefore a command to run it as root, or obtain a root shell with su. Before killing or terminating a process, you need to consider permissions.Ī root user can kill all processes.
