NAME
dvi2tty - preview a TeX DVI-file on an ordinary ascii terminal
SYNOPSIS
dvi2tty [ options ] dvi-file
DESCRIPTION
dvi2tty converts a TeX DVI-file to a format that is appropriate for terminals and line printers. The
program is intended to be used for preliminary proofreading of TeX-ed documents. By default the output
is directed to the terminal, possibly through a pager (depending on how the program was installed), but
it can be directed to a file or a pipe.
The output leaves much to be desired, but is still useful if you want to avoid walking to the laser
printer (or whatever) for each iteration of your document.
Since dvi2tty produces output for terminals and line printers the representation of documents is
naturally quite primitive. In principle Font Changes are totally ignored, but dvi2tty recognizes a few
mathematical and special symbols that can be be displayed on an ordinary ascii terminal, such as the '+'
and '-' symbol.
If the width of the output text requires more columns than fits in one line (c.f. the -w option) it is
broken into several lines by dvi2tty although they will be printed as one line on regular TeX output
devices (e.g. laser printers). To show that a broken line is really just one logical line an asterisk
(``*'') in the last position means that the logical line is continued on the next physical line output by
dvi2tty. Such a continuation line is started with a a space and an asterisk in the first two columns.
Options may be specified in the environment variable DVI2TTY. Any option on the command line,
conflicting with one in the environment, will override the one from the environment.
Options:
-o file
Write output to file ``file''.
-p list
Print the pages chosen by list. Numbers refer to TeX-page numbers (known as \count0). An example
of format for list is ``1,3:6,8'' to choose pages 1, 3 through 6 and 8. Negative numbers can be
used exactly as in TeX, e g -1 comes before -4 as in ``-p-1:-4,17''.
-P list
Like -p except that page numbers refer to the sequential ordering of the pages in the dvi-file.
Negative numbers don't make a lot of sense here...
-w n Specify terminal width n. Legal range 16-132. Default is 80. If your terminal has the ability to
display in 132 columns it might be a good idea to use -w132 and toggle the terminal into this mode
as output will probably look somewhat better.
-v Specify height of lines. Default value 450000. Allows to adjust linespacing.
-q Don't pipe the output through a pager. This may be the default on some systems (depending on the
whims of the person installing the program).
-e n This option can be used to influence the spacing between words. With a negative value the number
of spaces between words becomes less, with a positive value it becomes more. -e-11 seems to
worked well.
-f Pipe through a pager, $PAGER if defined, or whatever the installer of the program compiled in
(often ``more''). This may be the default, but it is still okay to redirect output with ``>'', the
pager will not be used if output is not going to a terminal.
-F Specify the pager program to be used. This overrides the $PAGER and the default pager.
-Fprog Use ``prog'' as program to pipe output into. Can be used to choose an alternate pager (e g
``-Fless'').
-t \tt fonts were used (instead of cm) to produce dvi file. (screen.sty is a powerfull mean to do
that with LaTeX).
-a Dvi2tty normally tries to output accented characters. With the -a option, accented characters are
output without the accent sign.
-l Mark page breaks with the two-character sequence ``^L''. The default is to mark them with a form-
feed character.
-c Do not attempt to translate any characters (like the Scandinavion/latin1 mode) except when running
in tt-font.
-u Toggle option to process certain latin1 characters. Use this if your output devices supports
latin1 cahracters. Note this may interfere with -s. Best not to use -u and -s together.
-s Toggle option to process the special Scandinavian characters that on most (?) terminals in
Scandinavia are mapped to ``{|}[\]''. Note this may interfere with -u. Best not to use -u and -s
together.
-J Auto detect NTT JTeX, ASCII pTeX, and upTeX dvi format.
-N Display NTT JTeX dvi.
-A Display ASCII pTeX dvi.
-U Display upTeX dvi.
-Eenc Set output Japanese encoding. The enc argument 'e', 's', 'j', and 'u' denotes EUC-JP, Shift_JIS,
ISO-2022-JP, and UTF-8, respectively.
-bdelim
Print the name of fonts when switching to it (and ending it). The delim argument is used to
delimit the fontname.
FILES
/bin/more probably the default pager.
ENVIRONMENT
PAGER the pager to use.
DVI2TTY can be set to hold command-line options.

BUGS
Blanks between words get lost quite easy. This is less likely if you are using a wider output than the
default 80.
Only one file may be specified on the command line.
