Subject: Re: Novice question, tranlate awk code to ruby code

This may not match the terseness of the awk script and
is certainly not the only way in Ruby, but is still a
one-liner (which may get mis-formated by the email
client):

C:\RB>type junk.dat
10      20      30
20      30      40
50      60      70
80  90  40

C:\RB>type junk.dat | ruby -ne "p $_.split('
').slice(0..1).collect{|e| e.to_i}.inject(1){|p,n|
p*n}"
200
600
3000
7200

C:\RB>ruby -v
ruby 1.8.0 (2003-08-04) [i386-mswin32]
