I updated this script! Forgot to bind the /hardcore command before. Grab it now!

I was surprised how easy it is to write an XChat plugin in Ruby, even though it would be cooler to see a the xchat-ruby bindings pimped out DSL style…oh well.

Download slashhardcore.rb

Windows users must modify @launcher to the path to their Winamp, Firefox, IE, or other shoutcast-compatible player.

# slashhardcore.rb - A faster way to tune in than the playlist bot.
# Should work on Windows if you set a valid browser/winamp location.
#
# Usage: Put in your $HOME/.xchat2 directory to autoload, and restart xchat,
# or type "/load /path/to/slashhardcore.rb"
#
# Commands: /pls <station, /stations (list stations), /hardcore

A simple Ruby script to kill all processes with a specific name.

Looking back on what I’ve done after a night’s rest with mixed horror and amusement, it seems this script is completely and totally useless, unless you’re looking for a half-hearted reimplementation of killall in Ruby. Why the hell did I write this?

Download the script to /usr/bin (or wherever) and chmod +x ./killevery

#!/usr/bin/ruby
def killevery(victim, options)
	processes = `ps -A | grep #{victim}`.scan(/(d+) .*/)
	if processes.length &gt; 0
		puts "Killing #{processes.length} processes named #{victim}"
		processes.each { |p|
			print `kill #{options} #{p}`
		}
	else
		puts "No processes are named #{victim}."
	end
end
if $*.length &lt; 1
	puts "Kill every process named &gt;name&lt;. Takes the same parameters as killall"
else
	killevery($*.pop, $*.join(' '))
end
