How to give arguments to kill via pipe

Question

I need to search for a certain process and kill that process. I wrote a command like this:

ps -e | grep dmn | awk '{print $1}' | kill

Where the process name is dmn. But it is not working. How can I find processes by name and kill them.

Solution 1

kill $(ps -e | grep dmn | awk '{print $1}')

Solution 2

In case there are multiple processes that you want to remove you can use this:

ps -efw | grep dmn | grep -v grep | awk '{print $2}' | xargs kill

Note: You need to remove grep process itself from the output, that's why grep -v grep is used.

Solution 3

You could use

pkill dmn 

if your system has the pkill command.

Solution 4

You might not need pipe for this, if you have pidof command and know the image name, I did it like this:

kill $(pidof synergyc)

$() I understand this as it converts that output to a variable that kill can use, essentially like pipe would do. Shorter and easier to understand than some other options but also maybe less flexible and more direct.

Solution 5

If you have the pidof command on your system ( I know shells such as ZSH come with this by default, unless I'm mistaken), you could do something like.

kill -9 $(pidof dmn)
