Re^2: How to write a program to read stdin or command line?

I don't see why -i is required. If it's not on the command line, then it must be on STDIN, so there's no reason to use -i.

my $input = @ARGV ? shift(@ARGV) : <STDIN>;

That's the approach <ARGV> uses.

Scalability / future expansion. The program may need other data on the command line unrelated to the need stated in the OP. Anyway, I didn't say `-i` is required. I answered the question "How would you...." And this is how I would. If you would do it otherwise, fine.	[reply] [d/l]
