How to kill all processes with a given partial name? [closed]

I want to kill all processes that I get by:

ps aux | grep my_pattern

How to do it?

This does not work:

pkill my_pattern

Use pkill -f, which matches the pattern for any part of the command line

pkill -f my_pattern

Just in case it doesn’t work, try to use this one as well:

pkill -9 -f my_pattern
