tc(1M)                                                               tc(1M)

NAME
     tc - troff output interpreter

SYNOPSIS
     tc [-t] [-o list] [-a n] [-e] [file]

DESCRIPTION
     tc interprets its input (standard input default) as output from
     troff(1M). The standard output of tc is intended for a TEKTRONIX 4015
     (a 4014 terminal with ASCII and APL character sets). The various
     typesetter sizes are mapped into the 4014's four sizes; the entire
     troff character set is drawn using the 4014's character generator,
     using overstruck combinations where necessary, producing an altogether
     displeasing effect. Typical usage:

          troff file | tc

     At the end of each page tc waits for a new-line (empty line) from the
     keyboard before continuing on to the next page. In this wait state,
     the following commands are recognized:

     !cmd Send cmd to the shell.

     e    Invert state of the screen erase

     -n   Skip backward n pages.

     an   Set the aspect ratio to n.

     ?    Print list of available options.

OPTIONS
     -t   Does not wait between pages (for directing output into a file).

     -o list
          Prints only the pages enumerated in list. The list consists of
          pages and page ranges (e.g. 5-17) separated by commas. The range
          n- goes from n to the end; the range -n goes from the beginning
          to and including page n.

     -a n Sets the aspect ratio to n; default is 1.5.

     -e   Does not erase before each page.

NOTES
     Font distinctions are lost.

     It needs a -w option to wait for input to arrive.
