i'm sure this is easy, but i've gone through Pickaxe's string methods,
searched the web and searched the groups, and i can't figure out how to
do this in Ruby.

i grep a file and it returns the following string:

#ip 127.0.0.1

i now want to get rid of "#ip" so i can then strip the remaining string
to get rid of spaces.

however, i can't find out how to delete the 3 leftmost characters - in
this case "#ip".

thanks for any tips to get this done - i would think it is a matter of
just knowing the correct method.
