Defining a variable from the command prompt

Ruby
1

hello,
I have a script that sends emails out to my company, and I would like
to be able to run it by saying (from the command prompt):

sendemail.rb “this is my message”

then it would take “this is my message” and use that as @msg or
something. I know its possible, but I’m still pretty new to Ruby and not
sure how to do this.

Any help is appreciated!

Thanks,

sendemail.rb “this is my message”

faq. research on ARGV

eg,

C:\family\ruby>cat test.rb
msg = ARGV[0] || “using default”
puts msg

C:\family\ruby>test.rb
using default

C:\family\ruby>test.rb “this is a test”
this is a test
