To provide a comparison of the previously mentioned approaches:

`ruby foo.rb` creates a completely separate interpreter, which you might or might not want. You can't directly access anything defined in one script in the other.

require is more commonly used to load libraries, since it will only process a file once; On the other side, load will always process the file.

For example, if you have (in the same directory) the files:

1. foo.rb

    puts "FOO"

2. bar.rb

    puts "BAR"

3. test.rb

    require 'foo'
    load 'bar.rb'

Then, unless I'm very much mistaken, the output will be:

    FOO
    BAR

Or,

`ruby filename.rb` # back-tics

which will trigger code that is testing to see if the file is called directly. E.g.:

if __FILE__ == $0
   # do me!
end
