Re: Ruby idiom equivalent to Perl "$asdf = $ARGV|| die 'arg required'"?]

Something like this, perhaps?

a = ARGV[0] || fail('arg required')

Here’s some more

a = ARGV.shift or raise “arg required”
a = ARGV.shift or raise ArgumentError, “arg required”

For more complex cmd line parsing I’d use OptionParser.

Kind regards
