in reply to Formatting Output

If you know ahead of time how wide each column is, use printf. If you want your columns to be auto-scaled for you, you can use a module like Text::Table.

    I was just about to suggest Text::Table, too. I love how you can have columns aligned by arbitrary characters (e.g., the decimal in a number). The only drawback is if you want to open your output in Excel or something, the columns don't get split as easily as if it were tab-delimited, etc.

      If you're going to be using Excel, why do you care what the bare output looks like?

        There have been times when I've generated tables that I like to examine using less, but others might need to open in Excel for their own reasons.
