Kill all processes macthing a pattern, ignoring case

Question

I want to have an alias to do something like pkill -f PATTERN but ignoring the case of the pattern. This is what I have after looking around but it's not working

alias pkf="kill `ps ax | grep -i $1 | awk '{ print $2 }'`"
alias pkf9="kill -9 `ps ax | grep -i $1 | awk '{ print $2 }'`"

Answer 1

man pkill :

       -i, --ignore-case
          Match processes case-insensitively

So :

pkill -fi PATTERN

Answer 2

You can use also killall. The command to ignore case will be:

killall -I process_name

WARNING: this command will work on this way only in Linux. Do not use it in AIX, Solaris, HP-UX!

According to the commit in GitHub killall is 21 years old.
