Hi all,

I wrote a program for work (I'm an undergraduate intern who taught himself Perl in about 3 weeks) that basically generates a giant report and dumps it to the terminal. It works great, but I'd like people to be able to pipe it to either dump to a file or use the "more" command, as in these examples: 

$ my_program > w00t.txt
$ my_program | more

[download]
I can easily implement either of these features from within the program, but I'd like to be able to this to make the program more "UNIX-like". I don't want to make people learn some new switch/flag/whatever when it's possible to use the UNIX pipes, especially if people want to use "cat", "lpr" or "grep", etc.

I'm not going to post the code here; it's pretty long, irrelevant to the question, and essentially the print to STDOUT happens within the last 5 lines.

So, how do I pipe my output to, say, "more"?

Thanks for all the help!
