Subject: Re: How to bail from an iteration but not the program?...

You can use 'break':

dcarrera ~ $ cat control.txt 
line 1
line 2
line 3
line 4
line 5
dcarrera ~ $ cat test.rb 
IO.foreach("control.txt") do |x|
        puts "Stuff A goes here: #{x}"
        break if x =~ /3/
end
puts "Stuff B goes here"
dcarrera ~ $ ruby test.rb 
Stuff A goes here: line 1
Stuff A goes here: line 2
Stuff A goes here: line 3
Stuff B goes here
dcarrera ~ $ 

Cheers,
Daniel.
