21.15. Making Text in Columns with pr

The pr command (Section 45.6) is famous for printing a file neatly on a page -- with margins at top and bottom, filename, date, and page numbers. It can also print text in columns: one file per column or many columns for each file.

The -t option takes away the heading and margins at the top and bottom of each page. That's useful when "pasting" data into columns with no interruptions.
