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 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 (cf. the -w op‐ tion) 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 con‐ tinued on the next physical line output by _dvi2tty._ Such a continuation line is started with 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 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 ### -q pending on the whims of the person installing the program). ### -e the number of spaces between words becomes less, with a positive value it becomes more. -e-11 seems to worked well. ### -f piled 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 and the default pager. ### -Fprog (e.g., ``-Fless''). ### -t ### -a characters are output without the accent sign. ### -l with a form-feed character. ### -c when running in tt-font. ### -u supports latin1 characters. Note this may interfere with -s. Best not to use -u and -s together. ### -s nals in Scandinavia are mapped to ``{|}[\]''. Note this may interfere with -u. Best not to use -u and -s together. ### -J ### -N ### -A ### -U ### -Eenc 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. ## SEE ALSO TeX, dvi2ps ## AUTHOR Original Pascal version: Svante Lindahl, Royal Institute of Technology, Stockholm Improved C version: Marcel Mol, MESA Consulting Now maintained at . ## BUGS Blanks between words get lost quite easily. This is less likely if you are using a wider out‐ put than the default 80. Only one file may be specified on the command line. 4 March 2021 [DVI2TTY(1)](https://www.chedong.com/phpMan.php/man/DVI2TTY/1/markdown)
