puts ARGV.count

if ARGV.count < 1
	puts "Missing argument - number of contacts"
	exit
end

first_name = "First"
last_name = "Last"
domain = "invalid.domain"

if ARGV.count == 4
	first_name = ARGV[1]
	last_name = ARGV[2]
	domain = ARGV[3]
end
email_address = first_name + "." + last_name

puts "attempting to generate file for " + ARGV[0] + " contacts ("+ARGV[0]+"contacts.csv) - with first name: " + first_name + " and last name: " + last_name

contact_count = Integer(ARGV[0])

File.open(ARGV[0]+"contacts.csv", 'w') {	|f| 
	f.write("id,first name, last name, email\n")
	for i in 1..contact_count do
		f.write(i.to_s + "," + i.to_s + first_name + "," + last_name + i.to_s + ","+email_address + i.to_s + "\@"+domain+"\n") 
 
	end
}

for i in 1..contact_count do
f.write("" + i.to_s + "," + i.to_s + first_name + "," + last_name + i.to_s + ","+email_address + i.to_s + "@"+domain+"\n")
end

That will generate the id field
