I was wondering how to run this ruby script.

The file name is check_payday.rb. Is there a specific folder location i should be saving this script to execute it?

#!/usr/bin/env ruby
# check_payday.rb

DAYS_IN_A_PAY_PERIOD = 14
SECONDS_IN_A_DAY     = 60 * 60 * 24

matching_date = Time.local(0, 0, 0, 22, 9, 2006, 5, 265, true, "EDT")
current_date = Time.new()

difference_in_seconds = (current_date - matching_date)
difference_in_days    = (difference_in_seconds / SECONDS_IN_A_DAY).to_i
days_to_wait          = (
  DAYS_IN_A_PAY_PERIOD - difference_in_days
) % DAYS_IN_A_PAY_PERIOD

if (days_to_wait.zero?)
  puts 'Payday today.' 
else
  print 'Payday in ' + days_to_wait.to_s + ' day'
  puts days_to_wait == 1 ? '.' : 's.' 
end

As long as Ruby is able to run, it doesn't matter where you save it. Just open a command prompt, get to that directory, and run ruby script_name.rb

Hmmm get to that directory? i think i missed that part.

I just open terminal and type check_payday.rb - it gave an error that file can't be found. How do i get to the directory? like can you show me an example ??

Very much appreciaited.

Well, first off, it depends on what OS you're running, and where the file is saved of course.

Like if the file were location at:

/home/[username]/Development/Ruby/check_payday.rb

You'd get there by typing

cd /home/[username]/Development/Ruby/

#Then type this to run it:
ruby check_payday.rb

Of course that's only on Linux and Mac OSX.

Ohh cool.

I just figured it out an hour ago. I saved the file on the desktop (Mac)

I typed ruby and the line below in my terminal.

/users/(myusername)/desktop/check_payday.rb

Why is CD used? im new to the terminal too.

Thank You

Cd is a command to navigate to a directory in the terminal.

Like:

cd /

Would make it so your terminal is operating in the root directory.
