How to exit Ruby program properly

Jeff

12/13/2005 3:57:00 AM

I'm learning to write ruby code, and I'm using 1.8.2 on Windows XP.
What is the best way to exit from my .rb script?

I'm using Process.exit but the documentation implies that it will throw
an exception. So I'm guessing there's a "cleaner" way to exit?

For example:

test.rb
====================
if ARGV.length == 0
puts "Please specify a filename"
Process.exit
end

# script continues here...


Thanks!
Jeff

just to save you 3.5 seconds of searching, it's Kernel.exit and exit!
we're talking about in the docs.

Will this actually work if a Thread (unjoined) does it?
Should experiment before asking, but I am in the middle of something else :)
Cheers,
