Below you’ll learn how to check running processes in Linux and identify their PPID from the terminal. So, if you can find out this PPID, then you’ll be able to send a kill signal using programs designed for this purpose. Moreover, each process has a single parent process with a unique PPID (Parent Process ID). There can be multiple PIDs associated with a process. So, whenever you invoke an application, the kernel will first spawn the necessary processes and assign them these unique PID values. These are created by the Linux kernel during runtime, and the process scheduler controls their CPU activities. The PID or process id is a unique number that identifies a process.

You are going to need the process id or PID information so that you can send them the required terminating signal. These commands work by sending specific signals to these unresponsive processes. There are several tools for terminating an unresponsive or hanged process from the command line, including kill, pkill, and killall. Terminate an Unresponsive Process From the Command Line Although this is a GNOME application, similar tools are available for other Linux desktop environments. We are going to leverage the ‘System Monitor’ application available in Ubuntu for this. You will also learn how to perform such Linux kill jobs from the graphical user interface or the X window. Once obtained successfully, we can use this PID to kill the program by sending specific signals to that PID. For this, we’ll first need to identify the process id. We’ll use the Linux terminal for the first method. We will mainly outline two methods for killing zombie processes. Different Methods of Killing a Dead Linux Process Linux is much more versatile than its counterparts and offers more than one method for tackling dead/unresponsive processes. Similarly, Mac users have the Command+Option+Escape method of killing frozen processes. If you’re coming from Windows, you might be familiar with Ctrl+Alt+Delete. You’ll learn several ways to terminate a Linux process that isn’t responding at all. Master Unresponsive Process Management in Linux
