To get the whole file in one string:
bytes = File.open("filename", "rb") { |file| file.read }
Sadly, you can''t do:
bytes = File.read("filename", "rb") # File::read assumes text mode
Anyway, "bytes" is now a string with the whole file in it. You can, of
course, read a certain number of bytes with "file.read(1024)" for
instance.
Sorry for any misinformation in this reply; it''s based on experience, not
knowledge ;)
