NAME
pdftex, pdfinitex, pdfvirtex - PDF output from TeX

SYNOPSIS
pdftex [options] [&format] [file|\commands]

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

pdfTeX is a version of TeX, with the e-TeX extensions, that can create PDF files as well as DVI files.

In DVI mode, pdfTeX can be used as a complete replacement for the TeX engine.

The  typical use of pdfTeX is with a pregenerated formats for which PDF output has been enabled.  The pdftex command uses the equivalent of
the plain TeX format, and the pdflatex command uses the equivalent of the LaTeX format.	To generate formats, use the -ini switch.

The pdfinitex and pdfvirtex commands are pdfTeX's analogues to the initex and virtex commands.  In this installation, if the  links  exist,
they are symbolic links to the pdftex executable.

In  PDF	mode,  pdfTeX can natively handle the PDF, JPG, JBIG2, and PNG graphics formats.  pdfTeX cannot include PostScript or Encapsulated
PostScript (EPS) graphics files; first convert them to PDF using epstopdf(1).  pdfTeX's handling of its command-line arguments  is  similar
to that of of the other TeX programs in the web2c implementation.

OPTIONS
This version of pdfTeX understands the following command line options.

-draftmode
Sets \pdfdraftmode so pdfTeX doesn't write a PDF and doesn't read any included images, thus speeding up execution.

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

-etex  Enable the e-TeX extensions.  This option is only effective in combination with -ini.  See etex(1).

-file-line-error
Print error messages in the form file:line:error which is similar 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 pdfTeX was called or a %& line.

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

-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 or PDF output to a socket as well as the usual output file.  Whether this option is available is the choice of the install-
er.

-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 of the input file.

Sets path searching debugging flags according to the bitmask.  See the Kpathsea manual for details.

-mktex fmt
Enable mktexfmt, where fmt must be either tex or tfm.

-mltex Enable MLTeX extensions.	Only effective in combination with -ini.

-no-mktex fmt
Disable mktexfmt, where fmt must be either tex or tfm.

-output-comment string
In DVI mode, use string for the DVI file comment instead of the date.  This option is ignored in PDF mode.

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

-output-format format
Set the output format mode, where format must be either pdf or dvi.  This also influences the set of graphics formats understood	by
pdfTeX.

-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 security
reasons.

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

-src-specials
In DVI mode, insert source specials into the DVI file.  This option is ignored in PDF mode.

-src-specials where
In DVI mode, insert source specials in certain placed of the DVI file.  where is a comma-separated value list:  cr,  display,  hbox,
math, par, parent, or vbox.  This option is ignored in PDF mode.

-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
See  the  Kpathsearch library documentation (the `Path specifications' node) for precise details of how the environment variables are used.
The kpsewhich utility can be used to query the values of the variables.

One caveat: In most pdfTeX formats, you cannot use ~ in a filename you give directly to pdfTeX, because ~ is an active character, and hence
is expanded, not taken as part of the filename.	Other programs, such as Metafont, do not have this problem.

TEXMFOUTPUT
Normally,  pdfTeX puts its output files in the current directory.  If any output file cannot be opened there, it tries to open it in
the directory specified in the environment variable TEXMFOUTPUT.	There is no default value for that variable.  For example, if  you
say  pdftex  paper  and  the  current  directory	is  not  writable  and	TEXMFOUTPUT  has the value /tmp, pdfTeX attempts to create
/tmp/paper.log (and /tmp/paper.pdf, if any output is produced.)  TEXMFOUTPUT is also checked for input files, as TeX often generates
files  that  need  to be subsequently read; for input, no suffixes (such as ``.tex'') are added by default, the input name is simply
checked as given.

TEXINPUTS
Search path for \input and \openin files.  This should 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/user/tex:" to
prepend the current directory and ``/home/user/tex'' to the standard search path.

TEXFORMATS
Search path for format files.

TEXPOOL
search path for pdftex internal strings.

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

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

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

pdftex.pool
Text file containing pdfTeX's internal strings.

pdftex.map
Filename mapping definitions.

*.tfm  Metric files for pdfTeX's fonts.

*.fmt  Predigested pdfTeX format (.fmt) files.

NOTES
Starting with version 1.40, pdfTeX incorporates the e-TeX extensions, and pdfeTeX is just a copy of pdfTeX.  See etex(1).  This manual page
is not meant to be exhaustive.  The complete documentation for this version of pdfTeX can be found in the pdfTeX manual and the info manual
Web2C: A TeX implementation.

BUGS
This version of pdfTeX implements a number of optional extensions.  In fact, many of these extensions  conflict	to  a  greater	or  lesser
extent  with the definition of pdfTeX.  When such extensions are enabled, the banner printed when pdfTeX starts is changed to print pdfTeXk

This version of pdfTeX fails to trap arithmetic overflow when dimensions are added or subtracted.  Cases where this occurs  are	rare,  but
when it does the generated DVI file will be invalid.  Whether a generated PDF file would be usable is unknown.

AVAILABILITY
pdfTeX is available for a large variety of machine architectures and operation systems.	pdfTeX is part of all major TeX distributions.
