Reads a user:password file named htpasswd and updates all passwords in every *.auth file.

updateGroups.rb

#!/usr/bin/env ruby

# Use htpasswd.py to add users to htpasswd file:
# touch ./htpasswd
# ./htpasswd.py -b ./htpasswd admin password
# ./htpasswd.py -b ./htpasswd alice password
# Add usernames to group files
# touch ./admins.auth
# touch ./users.auth
# echo "admin:..." >> admins.auth
# echo "alice:..." >> users.auth
# Now update groups with passwords
# ./updateGroups.rb

passwords = File.new('./htpasswd','r')

while pwline = passwords.gets
	pwline.strip!
	next if pwline.empty?

	user, _ = pwline.split(':')
	%x(sed -i 's/#{user}:.*/#{pwline.gsub('/','\/')}/g' *.auth)
