Hi everyone,


I know this is an easy question, but I want to know the best way to do this
(i.e. the most Rubyesque).

How do I strip the last four characters off a string of undetermined length?
I'm sure it is a one liner and doesn't require regexp. I currently have:

irb(main):010:0> a0/tcp'
"80/tcp"
irb(main):011:0> a[0,a.length-4]
"80"

irb(main):010:0> b666/tcp'
"5666/tcp"
irb(main):011:0> b[0,a.length-4]
"5666"

Which is two lines, but I'm hoping you smart guys can help me out ;) I'm
guessing "chop" would work, but I'm not sure if that's the most elegant
solution

Cheers,

Chris
