Question: How to Kill Process in Linux?

To kill the above process PID, use the kill command as shown.

The above command will kill the process having pid=3139, where PID is a Numerical Value of process.

Another way to perform the same function, can be rewritten as.pkill is what I recommend, if it’s available (Linux, FreeBSD, NetBSD, OpenBSD, Solaris).

You can specify processes by the command name, by the full command line or other criteria.

For example, pkill vi kills all programs whose command name contains the substring vi .

To kill only processes called vi , use pkill -x vi .There is one exception: even root cannot send a fatal signal to PID 1 (the init process).

However kill -9 is not guaranteed to work immediately.

All signals, including SIGKILL, are delivered asynchronously: the kernel may take its time to deliver them.

How do I stop a process in Linux?

Here’s what you do:

• Use the ps command to get the process id (PID) of the process you want to terminate.
• Issue a kill command for that PID.
• If the process refuses to terminate (i.e., it is ignoring the signal), send increasingly harsh signals until it does terminate.

kill command examples to kill a process on Linux

1. Step 1 – Find out the PID (process id) of the lighttpd. Use the ps or pidof command to find out PID for any program.
2. Step 2 – kill the process using a PID. The PID # 3486 is assigned to the lighttpd process.
