Getting command line

Joe Van Dyk

Hi,

If I launch a Ruby process with:
ruby something.rb lots of "stuff here" and I want all 'of it'

How can I get a string from inside the ruby process with:
lots of "stuff here" and I want all 'of it'
in it?

ARGV is an array of the tokens on the command line that follow the name
of the script. If you want them all in one string you can use the join
method to join them together.

puts ARGV.join(' ')

Of course, if you (the OP) want the quotes, you'll have to escape
them or the shell will strip them.

Oh yeah, I forgot that the shell automatically escapes stuff. Thanks.
