Hi,
Sorry for this silly question, but I don't remember how to insert text
to the beginning of a string. It's like the concatenate (or <<) operator
but it adds text before.
Thanks

I recommend studying this page, it's good to be familiar with the
methods in class String:
http://ruby-doc.org/core/classes/String.html
The one you are looking for is:
irb(main):001:0> s = "world"
=> "world"
irb(main):002:0> s.insert(0, "hello ")
=> "hello world"
irb(main):003:0> s
=> "hello world"
Hope this helps,
Jesus.

irb(main):002:0> s.insert(0, "hello ")
['hello ', s].join
...and how about unshift?
Any sicker ways out there?? Besides s = 'hello ' + s?

Just a note: both your join method and the + method above will create
a new string object, while the other methods in this thread (insert,
[/\A/], [0,0]) will modify the string in place. This might or might
not matter to the OP.
Regards,
Jesus.
