NAME

tc − troff output interpreter

SYNOPSIS

tc [ −t ] [ −olist ] [ −a n ] [ −e ] [ files ]

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 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 [ options ] files | 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 sends cmd to the shell. 

e inverts state of the screen erase (tc).

−n skips backward n pages. 

a n sets the aspect ratio to n.

?  prints list of available options. 

The command line options are:

−t Do not wait between pages (for directing output into a file). 

−olist 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 Set the aspect ratio to n; default is 1.5.

−e Do not erase before each page.

4014(1), nroff(1), troff(1). 

BUGS

Font distinctions are lost. 
It needs a −w option to wait for input to arrive.
