UNIX for Advanced & Expert Users

Hello everyone, this is my first post.

I have a problem using killall with a python script, I cannot make it work. How should I make the call?

Welcome to the forum

Your post should have been a new thread and not adding to the existing one !

ps -ef|grep scriptname|awk '{print $2}'|xargs kill -9

Once again, no need to kill -9. Why use a bazooka when a bow and arrow will do? A normal kill (equivalent to kill -15 or kill -TERM) gives the process to be killed an opportunity to catch the signal, close files and network connections, release shared memory and other IPC resources, and terminate cleanly. kill -9 does not give it this opportunity.

era was right the first time...

use pidof if you can:

on my linux system ps has a -C switch to select by command name i.e.

ps -C httpd -o pid=

will output the pids of the webserver processes running

Then again, linux mostly also has pidof as well, so that would be easier.

To get the row out of a ps listing for one process using grep, and to not get the grep row I use:

ps -ef |grep httpd |grep -v grep

Though that won't help if your grep doesn't have the -v switch.

wempy, another neat trick to do that with just one grep:

Code:

ps -ef | grep [h]ttpd
