Click on any of the 687 commands below to get a description and list of available options. All links in the command summaries point to the online version of the book on Safari Bookshelf.
A postprocessing filter that handles reverse linefeeds and escape characters, allowing output from tbl or nroff to appear in reasonable form on a terminal.
Ignore backspace characters; helpful when printing manpages.
Process half-line vertical motions, but not reverse line motion. (Normally, half-line input motion is displayed on the next full line.)
Buffer at least n lines in memory. The default buffer size is 128 lines.
Normally, col saves printing time by converting sequences of spaces to tabs. Use -x to suppress this conversion.
Run myfile through tbl and nroff, then capture output on screen by filtering through col and more:
tbl myfile | nroff | col | more
Save manpage output for the ls command in out.print, stripping out backspaces (which would otherwise appear as ^H):
man ls | col -b > out.print
