NAME

       LyX - A Document Processor

SYNOPSIS

       lyx [ command-line switches ] [ name[.lyx] ... ]

DESCRIPTION

       LyX  is too complex to be described completely in the "man" page format. If your system is
       properly configured, you can access the full documentation within LyX under the Help menu.

       LyX is a document preparation system. It excels at letting you  create  complex  technical
       and  scientific articles with mathematics, cross-references, bibliographies, indices, etc.
       It is very good at documents of any length in which the  usual  processing  abilities  are
       required: automatic sectioning and pagination, spellchecking, and so forth. It can also be
       used to write a letter to your mom, though granted, there are  probably  simpler  programs
       available  for  that.  It is definitely not the best tool for creating banners, flyers, or
       advertisements, though with some effort all these can be done, too.  Some examples of what
       it  is  used  for:  memos,  letters,  dissertations  and  theses,  lecture  notes, seminar
       notebooks, conference proceedings, software documentation, books  (on  PostgreSQL,  remote
       sensing,  cryptology,  fictional  novels,  poetry,  and  even  a  children's book or two),
       articles  in  refereed  scientific  journals,  scripts  for  plays  and  movies,  business
       proposals... you get the idea.

       Currently,  LyX  uses  the Qt4 library as a toolkit. LyX should run everywhere, where this
       library runs.  This is on all major Unix platforms as well as Windows and Mac OS X  (which
       actually is a unix platform).

OPTIONS

       LyX supports the following command-line switches.

       -help summarizes LyX usage

       -version
             provides version information on the build of LyX.

       -sysdir directory
             sets system directory. Normally not needed.

       -userdir directory
             sets user directory. Needed if you want to use LyX with different lyxrc settings.

       -geometry WxH+X+Y
             set geometry of the main window.

       -dbg feature[,feature...]
             where  feature  is  a  name  or number.  Use "lyx -dbg" to see the list of available
             debug features.

        -x [--execute] command
             where command is a lyx command.

        -e [--export] fmt
             where fmt is the export format of choice (latex,  pdflatex,  luatex,  xetex,  xhtml,
             text, lyx, ps, pdf, ...).  Note that the order of -e and -x switches matters.

        -E [--export-to] fmt filename
             where  fmt  is  the  export  format  of  choice  (see --export), and filename is the
             destination filename. Note that any additional  external  file  needed  by  filename
             (such  as  image  files)  will be exported as well to the folder containing filename
             (preserving the relative path embedded within the original LyX document, if any).

        -i [--import] fmt file.xxx
             where fmt is the import format of choice and file.xxx is the file to be imported.

        -f [--force-overwrite] what
             where what is is either "all", "main" or "none".  Specify "all" to allow overwriting
             all  files during a batch export, "main" to allow overwriting the main file only, or
             "none" to disallow overwriting any file. When this switch is  followed  by  anything
             else  other than "all", "main" or "none", the behavior is as if "all" was specified,
             but what follows is left on the command line for further processing.

        --ignore-error-message which
             allows you to ignore specific LaTeX error messages.  Do not use for final documents!
             Currently supported values: "missing_glyphs" Fontspec "missing glyphs" error.

        -n [--no-remote]
             open  documents  passed  as arguments in a new instance, even if another instance of
             LyX is already running.

        -r [--remote]
             by using the lyxpipe, ask an already running instance of LyX to open  the  documents
             passed as arguments and then exit. If the lyxpipe is not set up or is not working, a
             new instance is created and execution continues normally.

        -v [--verbose]
             print on terminal all spawned external commands.

       -batch
             causes LyX to run the given commands without opening a GUI window.  Thus,  something
             like:
                 lyx -batch -x "buffer-print printer default dvips" myfile.lyx
             will  cause  LyX  to  print  myfile.lyx  to the default printer, using dvips and the
             default print settings (which, of course, have to have been configured already).

ENVIRONMENT

       LYX_DIR_23x
              can be used to specify which system directory to use.

       The system directory is determined by searching for the file "chkconfig.ltx".  Directories
       are searched in this order:
       1) -sysdir command line parameter
       2) LYX_DIR_23x environment variable
       3) Maybe <path of binary>/TOP_SRCDIR/lib
       4) <path of binary>/../share/<name of binary>/
       5) hardcoded lyx_dir (at build time: /usr/share/lyx)

       LYX_USERDIR_23x
              can be used to specify which user directory to use.

       The user directory is, in order of precedence:
       1) -userdir command line parameter
       2) LYX_USERDIR_23x environment variable
       3) $HOME/.<name of binary> if no explicit setting is made

       LYX_LOCALEDIR
              can  be  used  to tell LyX where to look for the translations of its GUI strings in
              other languages.

       LYX_FORCE_OVERWRITE
              can be used to change the default behavior when exporting from command line.

       By default, LyX overwrites the main file when exporting from  command  line  but  not  the
       ancillary  files. This behavior can be changed by setting this environment variable, which
       relieves the need of using the -f switch.  Allowed values  are  either  "all",  "main"  or
       "none", with same meaning as for the -f switch.

BUGS/LIMITATIONS

       There  are  still some bugs in LyX. To report one, read if possible the Introduction found
       under the Help menu in LyX. You'll find detailed info on submitting bug reports there.  If
       you    can't    do   that,   send   details   to   the   LyX   Developers   mailing   list
       lyx-devel@lists.lyx.org,      or      use      the      LyX      bug      tracker       at
       http://www.lyx.org/trac/wiki/BugTrackerHome.   Don't  forget  to mention which version you
       are having problems with!

       LaTeX import is still not perfect and may produce buggy *.lyx files. Consult  the  tex2lyx
       documentation.
