However, knowing how to kill a screen session is essential to free up system resources and prevent processes from running indefinitely. Wrap UpĪ screen session is a powerful feature in Linux that allows running multiple terminal sessions within a single shell window. Verificationįor more satisfaction, use the “screen -ls” command to ensure that the session has been terminated. This will kill all processes with “screen” in their name, including all screen sessions. For instance, the command below will kill all the sessions with a screen in their name. The pkill command can be used with the process name to kill all the instances. However, it is necessary to keep the session’s name in mind. This method is useful if you need to know the PID of the screen session. The pkill command is a more powerful version of the kill command that allows you to kill processes by name. Verificationįor verification, you can use the “screen -ls” command to ensure the screen session has been terminated. The specific screen session(s) has been terminated. The command provided below will kill the screen session having process id 18460: $ kill 18460 Once you have the PID, you can use the kill command to terminate the session and all its child processes. Step 2: Kill the Screen Session Using its Process ID Look for the process with the name of your screen session, and note its PID. This will display a list of all processes with “SCREEN” in the name. To do this, first, you need to find the PID of the screen session using the following command: $ ps -ef | grep SCREEN Step 1: Get the Process ID of the Screen Session This method is useful to kill a screen session and all of its child processes. Method 2: Using the kill commandĪnother method for killing a screen session is by using the kill command. The command’s output shows there is no screen session currently onboard. Again, use the “screen ls” command as follows: $ screen -ls Now, let’s verify whether the session has been terminated or not. Note: Whenever you are about to terminate a screen session, you will automatically be navigated to the screen command. When the command is executed, it will show the interface as below: ExampleĪs in our case, the session Id is 18313, so the command would be: $ screen -X -S 18313 quit Replace with the ID of the screen session you want to kill. To kill a specific screen session, you need to put the session ID by following the below-mentioned command: $ screen -X -S quit This will display a list of all active screen sessions, their process IDs (PIDs), and other information. To do this, you first need to list all active screen sessions using the following command: $ screen -ls The simplest method for killing a screen session is by using the screen command. As a reference, we will perform the practical demonstration of these commands on Ubuntu 22.04. Note: The commands to kill a screen session are the same across all the Linux distributions. In some cases, this can cause system instability or even crashes.Ĭonsidering the importance of killing a screen session, this post will demonstrate numerous methods to kill a screen session on Linux. If a process is left running in the background of a terminal session, it can consume system resources even after you close the terminal window. It is important to kill a terminal session, including a screen session, because it frees up system resources and prevents processes from running indefinitely. It allows you to detach from a terminal session and then re-attach it later. In Linux, a screen session is a way to run multiple terminal sessions within a single shell window.
