Linux Terminating Process Operation

With the widespread popularity of Linux, it has become a preferred operating system for geeks. Whether its a web server, a developer on his own machine, or an enthusiast running the odd application, almost everyone is using Linux systems these days. Terminating processes are one of the essential strides in system administrators’ daily tasks.

In this article, we will explain how to terminate a running process in Linux using the command line. We’ll explain how to find the running process; how to figure out what to do with signal and signal lists; and how to safely terminate processes without affecting other running applications on the system.

Step 1: Find theProcessID

The first step is to find the process ID (PID) of the process you wish to terminate. Find thePIDusing the following command:

ps aux | grep the_process

This will list all the processes with the name “the_process”. Find the process you want to terminate and its PID.

Step 2: Send theSignal

There are different types of signals that can be sent to processes. Each signal has a different purpose and effect on the target process. The most common signal is SIGTERM (15), which is the default signal sent when terminating a process using the kill command. To terminate the process using thePIDwe found in step 1, run the following command:

kill -SIGTERM [pid]

Step 3: Verify theProcess Has Terminated

Once you’ve sent the signal, you can verify the process is terminated by running the following command:

ps aux | grep the_process

You should not see the process listed in the output. If you do, repeat step 2 using the same PID.

In conclusion, detecting and terminating processes in Linux is a simple process if you know which tools to use. Use thepscommand to find thePID, thekillcommand to send the signal, and thepscommand again to check the process is not running anymore.
