You can load/access arguments via environmental variables. For
example, if you wanted to pass in some IP addresses:
desc "Just spitting out some IPs from the command line"
task :spit_addresses do
ENV["ADDRESSES"].split(",").each {|a| puts a }
end
and then call it with:
cap spit_addresses ADDRESSES=10.0.0.1,10.0.0.2,10.0.0.3
it would puts:
10.0.0.1
10.0.0.2
10.0.0.3
Hope that helps.
