Subject: Re: putting values in one lines

require 'stringio'

f = StringIO.new(<<ENDOFSTRING)
hello world
up    down stuff here
up    down aenet 4a 5a 6a
aenet up    down 4b 5b 6b
ENDOFSTRING

target_column = 6

results = f.grep(/up    down/).grep(/aenet/)
results.each {|line| puts line.split[target_column - 1]}

--output:--
6a
6b
