As others have already said, probably the best way to remove \n from a
string's end is chomp or chomp! (the version with ! does an edit in
place, the version without returns the modification without changing
the original string)

However, this method won't work if, as your subject line implies, you
end up wanting to remove something else from a string.

I would recommend looking at http://www.whytheluckystiff.net/ruby/pickaxe/html/ref_c_string.html

It will show you everything you need to know about lovely methods like
delete, gsub, tr, and more.
