NAME
tex, latex, bibtex, dvips, dviselect, mf - text formatting
and typesetting
SYNOPSIS
tex [ first-line ]
latex file[.tex]
dvips [ option ... ] dvifile
dviselect [ -s ] [ -i infile ] [ -o outfile ] list of pages
[ infile [ outfile ] ]
bibtex auxname
mf [ 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 trun-
cated) file name or a \controlsequence. Thus tex paper pro-
cesses 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
explicitly.
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 doc-
ument. Then a bibliography style file is executed to write
a \thebibliography environment.
The source file should have defined the bibliography (.bib)
files to search with the \bibliography command, and the bib-
liography style (.bst) file to execute with the
\bibliographystyle 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 separately, 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
Page 2 Plan 9 (printed 11/18/24)

both first and last are optional numeric strings, with nega-
tive 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 selec-
tors, 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 output if all its \count values are within any
one of the ranges listed on the command line. For example,
the command `dviselect *.1,35:' might select everything in
chapter 1, as well as pages 35 and up.
Instead of \count values, dviselect can also select by abso-
lute page number, indicated by a leading equal sign (=).
Ranges of absolute pages are also allowed: `dviselect =3:7'
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
Page 3 Plan 9 (printed 11/18/24)
TEX(1) TEX(1)
s to angle e (angles measured clockwise from the posi-
tive 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 illustra-
tion, 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 sup-
plied, 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.
