tc(1)                                                       tc(1)



NAME
     tc - interprets troff output for use at  a  vintage  display
     device

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

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

     -e   Does not erase before each page.

     -o list
          Prints only the pages enumerated in list.  The list
          consists of pages and page ranges (for example, 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.

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

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

     Typical usage is:

        troff troff-options file| tc

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

     !cmd Sends cmd to the shell.

     e    Inverts the state of the screen erase.

     n    Prints page n (previously printed).

     -n   Skips backward n pages.

     olist
          Sets -o list to list.

     p    Prints current page again.

tc(1)                                                       tc(1)



     an   Sets the aspect ratio to n.

     ?    Prints list of available options.

LIMITATIONS
     Font distinctions are lost.

     The tc command needs a -w option to wait for input to
     arrive.
