SYNOPSIS
tex [ first-line ]

DESCRIPTION
Tex formats interspersed text and commands and outputs a .dvi (`device independent') file.
An argument given on the command line behaves as the first input line. That line should begin with a (possibly truncated) file name or a
controlsequence. Thus tex paper processes the file paper.tex. The base name of paper becomes the jobname, and is used in forming output
file names. If no file is named, the jobname is texput. The default .tex extension can be overridden by specifying an extension explic-
itly.
The output is written on jobname.dvi, which can be printed using lp(1). A log of error messages goes into jobname.log.
As well as the standard TeX fonts, many PostScript fonts can be used (see the contents of /sys/lib/tex/fonts/psvf). The file testfont.tex
(in the standard macro directory) will print a table of any font.
These environment variables adjust the behavior of tex:
TEXINPUTS
Search path for input and openin files. It should be colon-separated, and start with dot. Default: .:/sys/lib/tex/macros
TEXFONTS
Search path for font metric files. Default: /sys/lib/tex/fonts/tfm
TEXFORMATS
Search path for format files. Default: /sys/lib/tex/macros
TEXPOOL
Search path for strings. Default: /sys/lib/tex
TEXEDIT
Template for the switch-to-editor-on-error option, with %s for the file name and %d for the line number. Default: /bin/ed %s
Latex is a version of tex with a standard set of macros loaded. Latex produces file.dvi and a cross-referencing file, file.aux. It might
be necessary to run latex twice, to get all of the cross-referencing done properly. Slitex is a variant of latex with fonts and commands
suitable for making slides.
Bibtex is a bibliography processing program, often used in conjunction with latex. Bibtex reads the top-level auxiliary (.aux) file output
by latex and creates a bibliography (.bbl) file to be included in the LaTeX source file. The auxname on the command line should be given
without an extension. Each cite in the source file is looked up in bibliography files to gather together those used in the document.
Then a bibliography style file is executed to write a hebibliography environment.
The source file should have defined the bibliography (.bib) files to search with the ibliography command, and the bibliography style
(.bst) file to execute with the ibliographystyle command. Bibtex searches the TEXINPUTS path for .bst files, and the BIBINPUTS path for
.bst files. The LaTeX manual describes how to make bibliography files.
Dvips converts .dvi files to PostScript, writing the result on standard output. It is normally invoked by lp(1), but if invoked sepa-
rately, the following options are useful:
-r reverse pages. -r0 means don't reverse pages (if reversing is default).
-Tdev output device: dev is one of laserwriter (default for dvips), fax, gnot, lino (the computer center's high resolution PostScript
service), or ljfour (600 dpi PostScript).
-L print paper in landscape mode.
-Z compress the fonts before sending them.
-Z0 don't compress the fonts before sending them.
The following environment variables affect dvips:
TEXPKS Search path for font bitmaps (PK files).
TEXVFONTS
Search path for virtual font descriptions.
Dviselect selects pages from a .dvi file, creating a new .dvi file. A range is a string of the form first:last where both first and last
are optional numeric strings, with negative numbers indicated by a leading underscore character (_). If both first and last are omitted,
the colon may also be omitted, or may be replaced with an asterisk (*). A TeX page selector is a list of pages separated by periods. A
list of pages is described by a set of page TeX page selectors, separated by commas and/or white space. Dviselect actually looks at the
ten count variables that TeX writes; the first of these (count0) is the page number, with count1 through count9 having varied uses
depending on which macro packages are in use. (Typically count1 is a chapter or section number.) A page is included in dviselect's out-
put if all its count values are within any one of the ranges listed on the command line. For example, the command might select everything
in chapter 1, as well as pages 35 and up.
Instead of count values, dviselect can also select by absolute page number, indicated by a leading equal sign (=). Ranges of absolute
pages are also allowed: will extract the third through seventh pages.
Dvips understands some extended graphics commands that can be output using tpic specials in the TeX source. Many of them work by building
up a path of x,y pairs, and then doing something with the path. The tpic coordinate system has its origin at the current dvi position when
a drawing special is emitted; all length arguments are in units of milli-inches, and the y-axis goes positive downward.
special{pa x y}
Add x,y to the current path.
special{fp}
Flush the current path: draw it as a polygonal line and reset the path to be empty.
special{da dlen}
Like fp but draw dashed line, with dashes dlen milli-inches long.
special{dt slen}
Like fp but draw a dotted line, with dots slen apart.
special{sp}
Like fp but draw a quadratic spline. The spline goes through the midpoints of the segments of the path, and straight pieces extend
it to the endpoints.
special{ar x y xr yr s e}
Draw a circular or elliptical arc with center at x,y and radii xr and yr. The arc goes clockwise from angle s to angle e (angles
measured clockwise from the positive x-axis).
special{pn n}
Set line width (pen diameter) to nmilli-inches.
special{bk}
Set shading to black (will fill the next object drawn with black).
special{sh}
Set shading to grey.
special{wh}
Set shading to white.
special{psfile=file options}
Include file, which should be a PostScript illustration, making its origin be the current dvi position. The default PostScript
transformation matrix will be in effect, but it can be modified by the options, a list of space-separated key=value assignments.
Allowed keys are: hoffset, voffset, hscale, vscale, angle, If supplied, these values are supplied to PostScript translate,scale, and
rotate" commands, in that order. Also, keys hsize and vsize may be supplied, to cause clipping to those sizes. Sizes and offsets
should be specified in points, angles should be specified in degrees.
All of the specials leave TeX at the same position on the page that it started in.
Mf runs metafont, program that produces fonts for TeX. It is used by dvips when bitmaps for a given font at a given size do not exist.
