A script that will randomize the signature file in my Thunderbird email account

rotate_thunderbird_sig.rb

#!/usr/bin/env ruby

require "fileutils"

#this is the file that we will write the chosen sig to
tbirdSigFile = "/home/lytithwyn/.thunderbird/r2hddzc6.default/sigs/lytithwyn@gmail.htm"

Dir.chdir(Dir.home() + "/sigs") do
    sigs = Dir.glob("*.htm");
    sigFileNumberToUse = rand(sigs.length);

    FileUtils.cp sigs[sigFileNumberToUse], tbirdSigFile
end

I found it really dumb that there wasn't a simple way to randomize the sig in Thunderbird. There was an add-on that was supposed to do this, but lots of people were complaining about it so I didn't even try it. I have this script running in my ~/.flubox/startup file, so I get a random sig every time I sign on.
