You *don't* want to decompress the file?

data = File.read("foo.gz")

You *do* want to decompress the file? Use the built-in zlib support:

require 'zlib'
data = Zlib::GzipReader.open("foo.gz") { |f| f.read }

The Standard Library is libraries that are all included with a Ruby distribution, but (unlike Core) are not included in the runtime by default. The only thing you need to do is:

    require 'zlib'
