NAME

       lynx  - a general purpose distributed information browser for the World
       Wide Web


SYNOPSIS

       lynx [options] [path or URL]

       use "lynx -help" to display a complete list of current options.


DESCRIPTION

       Lynx is a fully-featured World Wide Web (WWW) client for users  running
       cursor-addressable,   character-cell   display   devices  (e.g.,  vt100
       terminals, vt100 emulators running on Windows 95/NT or Macintoshes,  or
       any other "curses-oriented" display).  It will display hypertext markup
       language (HTML) documents containing links to  files  residing  on  the
       local  system,  as  well  as  files  residing on remote systems running
       Gopher, HTTP, FTP, WAIS, and NNTP servers.  Current  versions  of  Lynx
       run on Unix, VMS, Windows 95/NT, 386DOS and OS/2 EMX.

       Lynx  can  be  used  to access information on the World Wide Web, or to
       build information systems intended primarily  for  local  access.   For
       example,  Lynx  has  been used to build several Campus Wide Information
       Systems (CWIS).  In  addition,  Lynx  can  be  used  to  build  systems
       isolated within a single LAN.


OPTIONS

       At  start  up, Lynx will load any local file or remote URL specified at
       the command line.  For help with URLs, press "?"  or "H" while  running
       Lynx.  Then follow the link titled, "Help on URLs."

       Lynx  uses  only  long option names. Option names can begin with double
       dash as well, underscores and dashes can be intermixed in option  names
       (in  the reference below options are with one dash before them and with
       underscores).

       -      If the argument is only '-', then Lynx expects  to  receive  the
              arguments from stdin.  This is to allow for the potentially very
              long command line that can be associated with the  -get_data  or
              -post_data  arguments (see below).  It can also be used to avoid
              having sensitive information in the invoking command line (which
              would be visible to other processes on most systems), especially
              when the -auth or -pauth options are used.

       -accept_all_cookies
              accept all cookies.

       -anonymous
              apply   restrictions   for   anonymous   account,    see    also
              -restrictions.

       -assume_charset=MIMEname
              charset for documents that don't specify it.

       -assume_local_charset=MIMEname
              charset assumed for local files.

       -assume_unrec_charset=MIMEname
              use this instead of unrecognized charsets.

       -auth=ID:PASSWD
              set  authorization  ID  and  password for protected documents at
              startup.  Be sure to protect any script  files  which  use  this
              switch.

       -base  prepend  a request URL comment and BASE tag to text/html outputs
              for -source dumps.

       -bibp=URL
              specify a local bibp server (default http://bibhost/).

       -blink forces high intensity  background  colors  for  color  mode,  if
              available  and  supported  by the terminal.  This applies to the
              slang library (for a few terminal emulators),  or  to  OS/2  EMX
              with ncurses.

       -book  use  the bookmark page as the startfile.  The default or command
              line startfile is still set for the  Main  screen  command,  and
              will be used if the bookmark page is unavailable or blank.

       -buried_news
              toggles  scanning  of  news  articles for buried references, and
              converts them to news  links.   Not  recommended  because  email
              addresses  enclosed in angle brackets will be converted to false
              news links, and uuencoded messages can be trashed.

       -cache=NUMBER
              set the NUMBER of documents cached in memory.   The  default  is
              10.

       -case  enable case-sensitive string searching.

       -center
              Toggle center alignment in HTML TABLE.

       -cfg=FILENAME
              specifies  a  Lynx  configuration  file  other  than the default
              lynx.cfg.

       -child exit on left-arrow in startfile, and disable save to disk.

       -cmd_log=FILENAME
              write  keystroke  commands  and  related  information   to   the
              specified file.

       -cmd_script=FILENAME
              read  keystroke  commands  from the specified file.  You can use
              the data written using the -cmd_log option.   Lynx  will  ignore
              other  information which the command-logging may have written to
              the logfile.  Each line of the command script contains either  a
              comment beginning with "#", or a keyword:

            exit causes   the   script  to  stop,  and  forces  lynx  to  exit
                 immediately.

            key  the character value, in printable  form.   Cursor  and  other
                 special   keys  are  given  as  names,  e.g.,  "Down  Arrow".
                 Printable 7-bit ASCII codes are given as-is, and  hexadecimal
                 values represent other 8-bit codes.

            set  followed  by a "name=value" allows one to override values set
                 in the lynx.cfg file.

       -color forces color mode  on,  if  available.   Default  color  control
              sequences  which work for many terminal types are assumed if the
              terminal capability description does not specify how  to  handle
              color.   Lynx  needs  to  be compiled with the slang library for
              this flag, it is equivalent to setting the COLORTERM environment
              variable.   (If  color  support  is instead provided by a color-
              capable curses library like ncurses, Lynx relies  completely  on
              the  terminal  description  to  determine  whether color mode is
              possible, and this flag is not needed and thus unavailable.)   A
              saved  show_color=always  setting  found  in  a  .lynxrc file at
              startup has the same effect.  A saved show_color=never found  in
              .lynxrc on startup is overridden by this flag.

       -connect_timeout=N
              Sets the connection timeout, where N is given in seconds.

       -cookie_file=FILENAME
              specifies  a file to use to read cookies.  If none is specified,
              the default value  is  ~/.lynx_cookies  for  most  systems,  but
              ~/cookies for MS-DOS.

       -cookie_save_file=FILENAME
              specifies a file to use to store cookies.  If none is specified,
              the value given by -cookie_file is used.

       -cookies
              toggles handling of Set-Cookie headers.

       -core  toggles forced core dumps on fatal errors.  Turn this option off
              to ask lynx to force a core dump if a fatal error occurs.

       -crawl with -traversal, output each page to a file.  with -dump, format
              output as with -traversal, but to stdout.

       -curses_pads
              toggles  the  use  of  curses  "pad"  feature   which   supports
              left/right scrolling of the display.

       -debug_partial
              separate incremental display stages with MessageSecs delay

       -delay add DebugSecs delay after each progress-message

       -display=DISPLAY
              set the display variable for X rexec-ed programs.

       -display_charset=MIMEname
              set the charset for the terminal output.

       -dont_wrap_pre
              inhibit wrapping of text in <pre> when -dump'ing and -crawl'ing,
              mark wrapped lines in interactive session.

       -dump  dumps the formatted  output  of  the  default  document  or  one
              specified  on  the command line to standard output.  This can be
              used in the following way:

              lynx -dump http://www.subir.com/lynx.html

       -editor=EDITOR
              enable external editing, using the specified  EDITOR.  (vi,  ed,

       -emacskeys
              enable emacs-like key movement.

       -enable_scrollback
              toggles  compatibility  with  communication programs' scrollback

              your  executable,  but  when  it  is,  it  can be disabled for a
              session.

       -force_empty_hrefless_a
              force HREF-less 'A' elements to be empty (close them as soon  as
              they are seen).

              the document.

              listonly  hidden  links  are  shown  only  on  L)ist screens and
              listings generated by -dump or from the P)rint menu, but  appear
              separately  at  the  end  of  those  lists.  This is the default
              behavior.

              ignore hidden links do not appear even in listings.

              POST when the  documents  they  returned  are  sought  with  the
              PREV_DOC command or from the History List.

       -rlogin
              disable recognition of rlogin commands.

       -scrollbar
              toggles showing scrollbar.

       -scrollbar_arrow
              toggles showing arrows at ends of the scrollbar.

       -selective
              require .www_browsable files to browse directories.

       -short_url
              show  very  long URLs in the status line with "..." to represent
              the portion which cannot be displayed.  The beginning and end of
              the URL are displayed, rather than suppressing the end.

       -show_cursor
              If  enabled  the  cursor  will  not  be hidden in the right hand
              corner but will instead  be  positioned  at  the  start  of  the
              currently selected link.  Show cursor is the default for systems
              without FANCY_CURSES capabilities.   The  default  configuration
              can  be  changed  in  userdefs.h  or lynx.cfg.  The command line
              switch toggles the default.

       -show_rate
              If enabled the transfer  rate  is  shown  in  bytes/second.   If
              disabled,  no  transfer  rate  is  shown.   Use  lynx.cfg or the
              options menu to select KB/second and/or ETA.

       -soft_dquotes
              toggles emulation of the  old  Netscape  and  Mosaic  bug  which
              treated '>' as a co-terminator for double-quotes and tags.

       -source
              works  the  same  as  dump  but  outputs  HTML source instead of
              formatted text.

       -stack_dump
              disable SIGINT cleanup handler

       -startfile_ok
              allow non-http startfile and homepage with -validate.

       -stdin read the startfile from standard input (UNIX only).

       -syslog=text
              information for syslog call.

       -tagsoup
              initialize parser, using Tag Soup DTD rather than SortaSGML.

       -telnet
              disable recognition of telnet commands.

       -term=TERM
              tell Lynx what terminal type to assume it is talking to.   (This
              may  be  useful  for  remote  execution, when, for example, Lynx
              connects to a remote TCP/IP port that starts a script  that,  in
              turn, starts another Lynx process.)

       -timeout=N
              For  win32,  sets  the network read-timeout, where N is given in
              seconds.

       -tlog  toggles between using a Lynx Trace  Log  and  stderr  for  trace
              output from the session.

       -tna   turns on "Textfields Need Activation" mode.

       -trace turns  on  Lynx trace mode.  Destination of trace output depends
              on -tlog.

       -trace_mask=value
              turn on optional traces, which may result in  very  large  trace
              files.  Logically OR the values to combine options:
              1=SGML character parsing states
              2=color-style
              4=TRST (table layout)
              8=config (lynx.cfg and .lynxrc contents)
              16=binary string copy/append, used in form data construction.

       -traversal
              traverse  all http links derived from startfile.  When used with
              -crawl, each link that begins with the same string as  startfile
              is  output to a file, intended for indexing.  See CRAWL.announce
              for more information.

       trim_input_fields
              trim input text/textarea fields in forms.

       -underline_links
              toggles use of underline/bold attribute for links.

       -underscore
              toggles use of _underline_ format in dumps.

       -use_mouse
              turn on mouse support, if available.  Clicking  the  left  mouse
              button  on a link traverses it.  Clicking the right mouse button
              pops back.  Click on the top line to scroll up.   Click  on  the
              bottom  line to scroll down.  The first few positions in the top
              and bottom line may invoke additional functions.  Lynx  must  be
              compiled  with  ncurses  or  slang  to support this feature.  If
              ncurses is used, clicking the middle  mouse  button  pops  up  a
              simple  menu.  Mouse clicks may only work reliably while Lynx is
              idle waiting for input.

       -useragent=Name
              set alternate Lynx User-Agent header.

       -validate
              accept only  http  URLs  (for  validation).   Complete  security
              restrictions also are implemented.

       -verbose
              toggle  [LINK],  [IMAGE] and [INLINE] comments with filenames of
              these images.

       -version
              print version information.

       -vikeys
              enable vi-like key movement.

       -wdebug
              enable Waterloo tcp/ip packet debug (print to  watt  debugfile).
              This  applies  only  to  DOS  versions  compiled  with WATTCP or
              WATT-32.

       -width=NUMBER
              number of columns for formatting of dumps, default is 80.

       -with_backspaces
              emit backspaces in output if -dump'ing or -crawl'ing (like 'man'
              does)


COMMANDS

       o Use Up arrow and Down arrow to scroll through hypertext links.
       o Right arrow or Return will follow a highlighted hypertext link.
       o Left Arrow will retreat from a link.
       o  Type  "H"  or  "?"  for  online  help and descriptions of key-stroke
       commands.
       o Type "K" for a  complete  list  of  the  current  key-stroke  command
       mappings.


ENVIRONMENT

       In  addition  to various "standard" environment variables such as HOME,
       PATH, USER, DISPLAY, TMPDIR, etc, Lynx utilizes  several  Lynx-specific
       environment variables, if they exist.

       Others  may  be created or modified by Lynx to pass data to an external
       program, or for other reasons.  These are listed separately below.

       See also the sections on SIMULATED  CGI  SUPPORT  and  NATIVE  LANGUAGE
       SUPPORT, below.

       Note:   Not  all  environment variables apply to all types of platforms
       supported by Lynx, though most do.  Feedback on  platform  dependencies
       is solicited.

       Environment Variables Used By Lynx:

       COLORTERM           If set, color capability for the terminal is forced
                           on at startup time.  The actual value  assigned  to
                           the  variable  is  ignored.   This variable is only
                           meaningful  if  Lynx  was  built  using  the  slang
                           screen-handling library.

       LYNX_CFG            This  variable,  if  set, will override the default
                           location and name of the global configuration  file
                           (normally,   lynx.cfg)  that  was  defined  by  the
                           LYNX_CFG_FILE  constant  in  the  userdefs.h  file,
                           during  installation.   See the userdefs.h file for
                           more information.

       LYNX_LOCALEDIR      If set, this  variable  overrides  the  compiled-in
                           location  of  the  locale  directory which contains
                           native language (NLS) message text.

       LYNX_LSS            This variable, if set, specifies  the  location  of
                           the   default  Lynx  character  style  sheet  file.
                           [Currently only meaningful if Lynx was built  using
                           experimental color style support.]

       LYNX_SAVE_SPACE     This  variable,  if  set, will override the default
                           path prefix for files saved to disk that is defined
                           in  the  lynx.cfg  SAVE_SPACE:  statement.  See the
                           lynx.cfg file for more information.

       LYNX_TEMP_SPACE     This variable, if set, will  override  the  default
                           path  prefix  for  temporary files that was defined
                           during installation, as well as any value that  may
                           be assigned to the TMPDIR variable.

       MAIL                This variable specifies the default inbox Lynx will
                           check for new mail, if such checking is enabled  in
                           the lynx.cfg file.

       NEWS_ORGANIZATION   This  variable, if set, provides the string used in
                           the Organization: header of USENET  news  postings.
                           It  will  override  the setting of the ORGANIZATION
                           environment variable, if it is also  set  (and,  on
                           UNIX, the contents of an /etc/organization file, if
                           present).

       NNTPSERVER          If set, this variable specifies  the  default  NNTP
                           server  that  will  be used for USENET news reading
                           and posting with Lynx, via news: URL's.

       ORGANIZATION        This variable, if set, provides the string used  in
                           the  Organization:  header of USENET news postings.
                           On UNIX,  it  will  override  the  contents  of  an
                           /etc/organization file, if present.

       PROTOCOL_proxy      Lynx supports the use of proxy servers that can act
                           as firewall gateways and caching servers.  They are
                           preferable   to  the  older  gateway  servers  (see
                           WWW_access_GATEWAY, below).  Each protocol used  by
                           Lynx,  (http,  ftp,  gopher,  etc),  can  be mapped
                           separately by setting environment variables of  the
                           form    PROTOCOL_proxy    (literally:   http_proxy,
                           ftp_proxy,       gopher_proxy,       etc),       to
                           "http://some.server.dom:port/".    See  Lynx  Users
                           Guide for additional details and examples.

       SSL_CERT_DIR        Set   to   the   directory    containing    trusted
                           certificates.

       SSL_CERT_FILE       Set  to the full path and filename for your file of
                           trusted certificates.

       WWW_access_GATEWAY  Lynx still supports use of  gateway  servers,  with
                           the   servers  specified  via  "WWW_access_GATEWAY"
                           variables (where "access" is lower case and can  be
                           "http",  "ftp",  "gopher"  or "wais"), however most
                           gateway servers have been discontinued.  Note  that
                           you do not include a terminal '/' for gateways, but
                           do  for   proxies   specified   by   PROTOCOL_proxy
                           environment  variables.   See  Lynx Users Guide for
                           details.

       WWW_HOME            This variable, if set, will  override  the  default
                           startup   URL   specified   in   any  of  the  Lynx
                           configuration files.

       Environment Variables Set or Modified By Lynx:

       LYNX_PRINT_DATE     This variable is set by the Lynx p(rint)  function,
                           to   the   Date:  string  seen  in  the  document's
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           Date" under VMS.

       LYNX_PRINT_LASTMOD  This  variable is set by the Lynx p(rint) function,
                           to the Last Mod:  string  seen  in  the  document's
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           LastMod" under VMS.

       LYNX_PRINT_TITLE    This variable is set by the Lynx p(rint)  function,
                           to  the  Linkname:  string  seen  in the document's
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           Title" under VMS.

       LYNX_PRINT_URL      This  variable is set by the Lynx p(rint) function,
                           to  the  URL:  string  seen   in   the   document's
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           URL" under VMS.

       LYNX_TRACE          If set, causes Lynx to write a trace file as if the
                           -trace option were supplied.

       LYNX_TRACE_FILE     If set, overrides the compiled-in name of the trace
                           file, which is either  Lynx.trace  or  LY-TRACE.LOG
                           (the  latter  on the DOS platform).  The trace file
                           is in either case relative to the home directory.

       LYNX_VERSION        This variable is always set by  Lynx,  and  may  be
                           used  by an external program to determine if it was
                           invoked by Lynx.  See  also  the  comments  in  the
                           distribution's  sample  mailcap  file, for notes on
                           usage in such a file.

       TERM                Normally,  this  variable  is  used  by   Lynx   to
                           determine  the  terminal  type being used to invoke
                           Lynx.  If, however, it is unset at startup time (or
                           has  the value "unknown"), or if the -term command-
                           line option is used (see  OPTIONS  section  above),
                           Lynx  will  set  or  modify  its  value to the user
                           specified terminal type  (for  the  Lynx  execution
                           environment).   Note:  If set/modified by Lynx, the
                           values of  the  LINES  and/or  COLUMNS  environment
                           variables may also be changed.


SIMULATED CGI SUPPORT

       If built with the cgi-links option enabled, Lynx allows access to a cgi
       script directly without the need for an http daemon.

       When executing such  "lynxcgi  scripts"  (if  enabled),  the  following
       variables may be set for simulating a CGI environment:

       CONTENT_LENGTH

       CONTENT_TYPE

       DOCUMENT_ROOT

       HTTP_ACCEPT_CHARSET

       HTTP_ACCEPT_LANGUAGE

       HTTP_USER_AGENT

       PATH_INFO

       PATH_TRANSLATED

       QUERY_STRING

       REMOTE_ADDR

       REMOTE_HOST

       REQUEST_METHOD

       SERVER_SOFTWARE

       Other  environment  variables  are  not inherited by the script, unless
       they  are  provided  via  a  LYNXCGI_ENVIRONMENT   statement   in   the
       configuration  file.   See  the  lynx.cfg file, and the (draft) CGI 1.1
       Specification <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The  CGI  Specification,  and other associated documentation, should be
       consulted for general information on CGI script programming.


NATIVE LANGUAGE SUPPORT

       If configured and installed with Native  Language  Support,  Lynx  will
       display status and other messages in your local language.  See the file
       ABOUT_NLS in the source distribution, or at your local  GNU  site,  for
       more information about internationalization.

       The  following  environment  variables  may  be  used  to alter default
       settings:

       LANG                This variable, if set, will  override  the  default
                           message language.  It is an ISO 639 two-letter code
                           identifying the language.  Language codes  are  NOT
                           the same as the country codes given in ISO 3166.

       LANGUAGE            This  variable,  if  set, will override the default
                           message language.  This is a GNU extension that has
                           higher  priority  for  setting  the message catalog
                           than LANG or LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These variables, if  set,  specify  the  notion  of
                           native language formatting style.  They are POSIXly
                           correct.

       LINGUAS             This  variable,  if  set  prior  to  configuration,
                           limits  the installed languages to specific values.
                           It is a space-separated list of  two-letter  codes.
                           Currently, it is hard-coded to a wish list.

       NLSPATH             This  variable,  if set, is used as the path prefix
                           for message catalogs.

       Note that man page availability and section numbering is somewhat plat-
       form dependent, and may vary from the above references.

       A section shown as (GNU), is intended to denote that the topic  may  be
       available via an info page, instead of a man page (i.e., try "info sub-
       ject", rather than "man subject").

       A section shown as (?) denotes that documentation on the topic  exists,
       but  is  not part of an established documentation retrieval system (see
       the distribution files associated with the topic, or contact your  Sys-
       tem Administrator for further information).


ACKNOWLEDGMENTS

       Lynx  has  incorporated  code  from a variety of sources along the way.
       The earliest versions of Lynx included code from Earl Fogel of  Comput-
       ing  Services at the University of Saskatchewan, who implemented HYPER-
       REZ in the Unix environment.  HYPERREZ was developed by Niel Larson  of
       Think.com  and  served  as  the  model  for the early versions of Lynx.
       Those versions also incorporated libraries from the Unix Gopher clients
       developed  at  the  University  of Minnesota, and the later versions of
       Lynx rely on the WWW client library code developed by  Tim  Berners-Lee
       and  the  WWW  community.  Also a special thanks to Foteos Macrides who
       ported much of Lynx to VMS and did or organized most of its development
       since  the  departures of Lou Montulli and Garrett Blythe from the Uni-
       versity of Kansas in the summer of 1994 through the release of  v2.7.2,
       and  to  everyone  on the net who has contributed to Lynx's development
       either directly (through patches, comments or bug reports) or indirect-
       ly (through inspiration and development of other systems).
