dvi2tty - preview a TeX DVI-file on an ordinary ascii terminal
dvi2tty [ options ] dvi-file
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.
/bin/more probably the default
pager.
PAGER
the pager to use.
DVI2TTY
can be set to hold command-line options.

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.
