Basic Input and Output



Ruby provides what at first sight looks like two separate sets of I/O routines. The first is the simple interface---we've been using it pretty much exclusively so far.

print "Enter your name: "
name = gets

There are a whole set of I/O-related methods implemented in the Kernel module---gets, open, print, printf, putc, puts, readline, readlines, and test---that make it simple and convenient to write straightforward Ruby programs. These methods typically do I/O to standard input and standard output, which makes them useful for writing filters. You'll find them documented starting on page 411.

The second way, which gives you a lot more control, is to use IO objects.
