9 dvi2tty [ options ] dvifile

12 dvi2tty converts a TeX DVI file to a format that is appropriate for
13 terminals and line printers. The program is intended to be used for
14 preliminary proofreading of TeX-ed documents. By default the output is
15 directed to the terminal, possibly through a pager (depending on how
16 the program was installed), but it can be directed to a file or a pipe.
17 The output leaves much to be desired, but is still useful if you want
19 to avoid walking to the laser printer (or whatever) for each iteration
20 of your document.
21 Since dvi2tty produces output for terminals and line printers the rep‐
22 resentation of documents is naturally quite primitive. In principle
23 font changes are totally ignored, but dvi2tty recognizes a few mathe‐
24 matical and special symbols that can be displayed on an ordinary ASCII
25 terminal, such as the '+' and '-' symbol.
26 If the width of the output text requires more columns than fits in one
28 line (cf. the -w option) it is broken into several lines by dvi2tty al‐
29 though they will be printed as one line on regular TeX output devices
30 (e.g., laser printers). To show that a broken line is really just one
31 logical line an asterisk (``*'') in the last position means that the
32 logical line is continued on the next physical line output by dvi2tty.
33 Such a continuation line is started with a space and an asterisk in the
34 first two columns.
35 Options may be specified in the environment variable DVI2TTY. Any op‐
37 tion on the command line, conflicting with one in the environment, will
38 override the one from the environment.
39 Options:
41 -o file
43 Write output to file ``file''.
44 -p list
46 Print the pages chosen by list. Numbers refer to TeX page num‐
47 bers (known as \count0). An example of format for list is
48 ``1,3:6,8'' to choose pages 1, 3 through 6 and 8. Negative num‐
49 bers can be used exactly as in TeX, e.g., -1 comes before -4 as
50 in ``-p-1:-4,17''.
51 -P list
53 Like -p except that page numbers refer to the sequential order‐
54 ing of the pages in the dvi-file. Negative numbers don't make a
55 lot of sense here...
56 -w n Specify terminal width n. Valid range 16–132. Default is 80.
58 If your terminal has the ability to display in 132 columns it
59 might be a good idea to use -w132 and toggle the terminal into
60 this mode as output will probably look somewhat better.
61 -v Specify height of lines. Default value 450000. Allows one to ad‐
63 just linespacing.
64 -q Don't pipe the output through a pager. This may be the default
66 on some systems (depending on the whims of the person installing
67 the program).
68 -e n This option can be used to influence the spacing between words.
70 With a negative value the number of spaces between words becomes
71 less, with a positive value it becomes more. -e-11 seems to
72 worked well.
73 -f Pipe through a pager, $PAGER if defined, or whatever the in‐
75 staller of the program compiled in (often ``more''). This may be
76 the default, but it is still okay to redirect output with ``>'',
77 the pager will not be used if output is not going to a terminal.
78 -F Specify the pager program to be used. This overrides the $PAGER
80 environment variable and the default pager.
81 -Fprog Use ``prog'' as program to pipe output into. Can be used to
83 choose an alternate pager (e.g., ``-Fless'').
84 -t \tt fonts were used (instead of cm) to produce the dvi file.
86 -a Dvi2tty normally tries to output accented characters. With the
88 -a option, accented characters are output without the accent
89 sign.
90 -l Mark page breaks with the two-character sequence ``^L''. The de‐
92 fault is to mark them with a form-feed character.
93 -c Do not attempt to translate any characters (like the Scandina‐
95 vian/latin1 mode) except when running in tt-font.
96 -u Toggle option to process certain latin1 characters. Use this if
98 your output devices supports latin1 characters. Note this may
99 interfere with -s. Best not to use -u and -s together.
100 -s Toggle option to process the special Scandinavian characters
102 that on most (?) terminals in Scandinavia are mapped to
103 ``{|}[\]''. Note this may interfere with -u. Best not to use -u
104 and -s together.
105 -J Auto detect NTT JTeX, ASCII pTeX, and upTeX dvi format.
107 -N Display NTT JTeX dvi.
109 -A Display ASCII pTeX dvi.
111 -U Display upTeX dvi.
113 -Eenc Set output Japanese encoding. The enc argument 'e', 's', 'j',
115 and 'u' denotes EUC-JP, Shift_JIS, ISO-2022-JP, and UTF-8, re‐
116 spectively.
117 -bdelim
119 Print the name of fonts when switching to it (and ending it).
120 The delim argument is used to delimit the fontname.
121
123 /bin/more probably the default pager.
124
126 PAGER the pager to use.
127 DVI2TTY can be set to hold command-line options.
128
130 TeX, dvi2ps
131
133 Original Pascal version: Svante Lindahl, Royal Institute of Technology,
134 Stockholm
135 Improved C version: Marcel Mol, MESA Consulting
136 Now maintained at https://github.com/t-tk/dvi2tty/releases.
137
139 Blanks between words get lost quite easily. This is less likely if you
140 are using a wider output than the default 80.
141 Only one file may be specified on the command line.
