How do I tell from within a ruby script whether it has been run from the command line, i.e. like this:
> ruby myscript.rb
or from a non-interactive process, e.g. cron?
How do I tell from within a ruby script whether it has been run from the command line, i.e. like this:

$stdin.tty?
will return true if connected to a terminal otherwise false.
