Ruby Command Line

Today really quick I went through some of ruby tutorials on learn to code the hard way. Here are some of the things I learned:

• print is different than puts in that it doesn’t output a newline character.
• use the gets command to gather input from the user.
• use the gets.chomp command to remove the newline that gets added.
• use ARGV to get input from the command prompt.
• use the STDIN.gets.chomp command if you are using ARGV.
• use File.open() to open files.
