SYNOPSIS

       tex [options] [& format ] [ file | \ commands ]


DESCRIPTION

       Run the TeX typesetter on file, usually creating file.dvi.  If the file
       argument has no extension, ".tex" will be appended to it.  Instead of a
       filename,  a  set of TeX commands can be given, the first of which must
       start with a backslash.  With a &format argument TeX uses  a  different
       set  of  precompiled  commands,  contained in format.fmt; it is usually
       better to use the -fmt format option instead.

       TeX formats the interspersed text and commands contained in  the  named
       files  and  outputs a typesetter independent file (called DVI, which is
       short for DeVice Independent).  TeX's  capabilities  and  language  are
       described  in The TeX for nroffbook.  TeX is normally used with a large
       body of precompiled macros, and there are several  specific  formatting
       systems,  such  as  LaTeX,  which  require the support of several macro
       files.

       This version of TeX looks at its command line to see what name  it  was
       called  under.  If they exist, then both initex and virtex are symbolic
       links to the tex executable.  When called as initex (or when  the  -ini
       option  is given) it can be used to precompile macros into a .fmt file.
       When called as virtex it will use the plain format.  When called  under
       any  other  name,  TeX  will use that name as the name of the format to
       use.  For example, when called as tex the tex format is used, which  is
       identical  to the plain format.  The commands defined by the plain for-
       mat are documented in The TeX for nroffbook.  Other  formats  that  are
       often available include latex and amstex.

       The  non-option command line arguments to the TeX program are passed to
       it as the first input line.  (But it is often easier to  type  extended
       arguments  as the first input line, since UNIX shells tend to gobble up
       or misinterpret TeX's favorite symbols, like  backslashes,  unless  you
       quote  them.)   As  described in The TeX for nroffbook, that first line
       should begin with a filename, a \controlsequence, or a &formatname.

       The normal usage is to say
       tex paper
       to start processing paper.tex.  The name paper will be the ``jobname'',
       and is used in forming output filenames.  If TeX doesn't get a filename
       in the first line, the jobname is texput.  When looking for a file, TeX
       looks  for  the  name  with  and  without  the default extension (.tex)
       appended, unless the name already contains that extension.  If paper is
       the  ``jobname'', a log of error messages, with rather more detail than
       normally appears on the screen, will appear in paper.log, and the  out-
       put file will be in paper.dvi.

       This version of TeX can look in the first line of the file paper.tex to
       see if it begins with the magic sequence %&.  If the first line  begins
       with  %&format -translate-file tcxname then TeX will use the named for-
       mat and transation table tcxname to process the  source  file.   Either
       A convenient file in the library is null.tex, containing nothing.  When
       TeX  can't find a file it thinks you want to input, it keeps asking you
       for another filename; responding `null' gets you out of the loop if you
       don't  want  to  input  anything.  You can also type your EOF character
       (usually control-D).



OPTIONS

       This version of TeX understands the following command line options.

       -enc   Enable the encTeX extensions.  This option is only effective  in
              combination  with  -ini.  For documentation of the encTeX exten-
              sions see http://www.olsak.net/enctex.html.

       -file-line-error
              Print error messages in the form file:line:error which is  simi-
              lar to the way many compilers format them.

       -no-file-line-error
              Disable printing error messages in the file:line:error style.

       -file-line-error-style
              This is the old name of the -file-line-error option.

       -fmt format
              Use  format as the name of the format to be used, instead of the
              name by which TeX was called or a %& line.

       -halt-on-error
              Exit with an error code when an error is encountered during pro-
              cessing.

       -help  Print help message and exit.

       -ini   Start  in INI mode, which is used to dump formats.  The INI mode
              can be used for typesetting, but no  format  is  preloaded,  and
              basic initializations like setting catcodes may be required.

       -interaction mode
              Sets  the  interaction  mode.  The mode can be either batchmode,
              nonstopmode, scrollmode,  and  errorstopmode.   The  meaning  of
              these  modes is the same as that of the corresponding \commands.

       -ipc   Send DVI output to a socket as well as the  usual  output  file.
              Whether this option is available is the choice of the installer.

       -ipc-start
              As -ipc, and starts  the  server  at  the  other  end  as  well.
              Whether this option is available is the choice of the installer.

       -jobname name
              Use name for the job name, instead of deriving it from the  name

       -output-comment string
              Use string for the DVI file comment instead of the date.

       -output-directory directory
              directory instead of the current directory.  Look up input files
              in directory first, the along the normal search path.

       -parse-first-line
              If the first line of the main input file begins with %& parse it
              to look for a dump name or a -translate-file option.

       -no-parse-first-line
              Disable parsing of the first line of the main input file.

       -progname name
              Pretend  to  be program name.  This affects both the format used
              and the search paths.

       -recorder
              Enable the filename recorder.  This leaves a trace of the  files
              opened for input and output in a file with extension .fls.

       -shell-escape
              Enable  the \write18{command} construct.  The command can be any
              shell command.  This construct is normally disallowed for  secu-
              rity reasons.

       -no-shell-escape
              Disable  the  \write18{command} construct, even if it is enabled
              in the texmf.cnf file.

       -src-specials
              Insert source specials into the DVI file.

       -src-specials where
              Insert source specials in certain places of the DVI file.  where
              is  a  comma-separated value list: cr, display, hbox, math, par,
              parent, or vbox.

       -translate-file tcxname
              Use the tcxname translation table to set the  mapping  of  input
              characters and re-mapping of output characters.

       -default-translate-file tcxname
              Like  -translate-file  except  that  a %& line can overrule this
              setting.

       -version
              Print version information and exit.


ENVIRONMENT

              PUT.  There is no default value for that variable.  For example,
              if you say tex paper and the current directory is not  writable,
              if  TEXMFOUTPUT  has  the  value  /tmp,  TeX  attempts to create
              /tmp/paper.log (and /tmp/paper.dvi, if any output is  produced.)

       TEXINPUTS
              Search  path for \input and \openin files.  This should probably
              start with ``.'', so that user files  are  found  before  system
              files.   An empty path component will be replaced with the paths
              defined in the texmf.cnf file.  For example,  set  TEXINPUTS  to
              ".:/home/usr/tex:"   to   prepend   the   current  direcory  and
              ``/home/user/tex'' to the standard search path.

       TEXFORMATS
              Search path for format files.

       TEXPOOL
              search path for tex internal strings.

       TEXEDIT
              Command template for switching to editor.  The default,  usually
              vi, is set when TeX is compiled.

       TFMFONTS
              Search path for font metric (.tfm) files.

       The location of the files mentioned below varies from system to system.
       Use the kpsewhich utility to find their locations.

       texmf.cnf
              Configuration file.  This contains definitions of  search  paths
              as well as other configuration parameters like parse_first_line.

       tex.pool
              Text file containing TeX's internal strings.

TRIVIA

       TeX,   pronounced  properly,  rhymes  with  ``blecchhh.''   The  proper
       spelling in  typewriter-like  fonts  is  ``TeX''  and  not  ``TEX''  or
       ``tex.''


AUTHORS

       TeX  was  designed by Donald E. Knuth, who implemented it using his Web
       system for Pascal programs.  It was  ported  to  Unix  at  Stanford  by
       Howard  Trickey,  and  at  Cornell  by  Pavel  Curtis.  The version now
       offered with the Unix TeX distribution is that generated by the Web  to
       C system (web2c), originally written by Tomas Rokicki and Tim Morgan.

       The encTeX extensions were written by Petr Olsak.
