pass command line param. to ruby script?

I'm trying to find out if it's possible, and if so, how to pass a
command line parameter to a ruby script.

The reason for inquiring is that I'd like to have a for loop that runs
a few automated test cases (watir), but I want the user to be able to
specify the variable in the loop without editing the script itself.

Thanks!

put the following in the file and run it like so: ruby test.rb hello

#test.rb
puts ARGV[0] if ARGV[0]

What is that doing exactly? Is ARGV[0] the variable name for the first
parameter after the ruby script name?

You'll probably find it helpful to look at
<URL:http://www.ruby-doc.org/stdlib/libdoc/getoptlong/rdoc/inde...
now that I've documented it.

See also other useful libraries that do similar things, like Usage:

Yes, ARGV is an array of all the command line parameters, with 0 being
the 1st.

So the script is printing your first paramter if it exists.

Indeed.
