hello Ruby, goodbye perl, awk…

Ruby has been around for a while, I've been meaning to look at this for ages and when Jon Tirsen mentioned DamageControl is written in it, it was yet another push for me to have a squiz.

I had a superficial look mainly from a scripting point of view and it looks great, I might never have to write another awk script again!

Here is the socketcount program from a recent post rewritten in ruby.

#!/usr/bin/ruby
#socketcount in ruby
if $*.size > 0
regex = $*[0]
else
regex = '^..p'
end
result = %x{sudo netstat -tpa | grep #{regex} | grep -v LISTEN }
# All Socket connections counted (originating and terminating)
h = {}
result.each() { |s|
service = s.split(' ')[4]
h[service] = h[service].to_i + 1
}
h.each { | key, value | print key, " ",value, "n" }


It suits my purposes for scripting and seems to be pretty impressive in other aspects.
