TC(1)

NAME
tc - troff output interpreter

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

DESCRIPTION
tc interprets its input from file (default is standard input) 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 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]
inverts state of the screen erase.

    [- n]
skip backward
    n pages.

    [a n]
sets the aspect ratio to
    n.

    [?]
prints list of available options.

The command line options are:

[-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.

BUGS
Font distinctions are lost.
tc needs a [-w] option to wait for input to arrive.
