This is my code:
if ARGV[0] == false
puts "Usage: ./script.rb argument"
exit
end
print "Yey we got an argument: " ARGV[0]
But I just cant make the code check if ARGV[0] is given or not, how should I do that ?
Check if it’s
empty?(or check its length):Consider using any of the Ruby command line argument parsers, like OptionParser.
