#### NAME

```       aleph - extended Unicode TeX

```

#### SYNOPSIS

```       aleph [options] [&format] [file|\commands]

```

#### DESCRIPTION

```       Run  the Aleph 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 Aleph  commands
can  be  given,  the  first of which must start with a backslash.  With a &format argument
Aleph uses a different set of precompiled commands, contained in format.fmt; it is usually
better to use the -fmt format option instead.

Aleph  is  a  version  of  the TeX program modified for multilingual typesetting.  It uses
Unicode, and has additional primitives for (among other things) bidirectional typesetting.

Aleph's command line options are similar to those of TeX.

Aleph is no longer being actively developed; see LuaTeX for current activity.

```

#### OPTIONS

```       Run aleph --help to see the complete list of options; this is not exhaustive.

--fmt format
Use format as the name of the format to be used, instead of the name by which Aleph
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  Be  `initial'  Aleph for dumping formats; this is implicitly true if the program is
called as inialeph.

--interaction mode
Sets the interaction  mode.   The  mode  can  be  one  of  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.

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

--maketex fmt
Enable mktexfmt, where fmt must be one of tex or tfm.

--no-maketex fmt
Disable mktexfmt, where fmt must be one of tex or tfm.

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

--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.

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

--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 .ofl.  (This option is always on.)

--shell-escape
Enable  the  \write18{command}  construct.   The  command  can  be any Bourne shell
command.  By default, this construct is enabled in a restricted mode, for  security
reasons.

--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  Aleph formats, you cannot use ~ in a filename you give directly to
Aleph, 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, Aleph 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 tex paper and the current directory  is  not  writable,  if
TEXMFOUTPUT  has  the  value  /tmp,  Aleph  attempts  to create /tmp/paper.log (and
/tmp/paper.dvi, 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 direcory and ``/home/user/tex''  to  the
standard search path.

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

#### NOTES

```       This manual page is not meant to be  exhaustive.   The  complete  documentation  for  this
version  of  Aleph  can  be  found  in  the  info manual Web2C: A TeX implementation.  See
http://tug/org/web2c.

```

#### BUGS

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

This  version  of  Aleph  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.
