zipup.rb

# A ruby script to create a zip file of katas whose total number
# of traffic-lights is greater than Parameter-1 and
# that are at least Parameter-2 days old.
# This allows the subsequent deletion of said katas
# which is important as cyber-dojo is very heavy on inodes.
#
# Step 1
#     >ruby zipup.rb false 200 7
# if there are a lot of won't and you just want to see the wills
#     >ruby zipup.rb false 200 7 | grep "will"
# then
#     >ruby zipup.rb true 200 7
#
# Step 2 - sftp the zip file off the server.
#
# Step 3
#     >ruby prune_large.rb false 200 7
#     >ruby prune_large.rb true  200 7
