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 termi-
       nals, 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	 iso-
       lated 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 com-
	      mand  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 -restric-
	      tions.

       -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 speci-
	      fied 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  immedi-
		 ately.

	    key	 the  character	 value,	 in printable form.  Cursor and other
		 special keys are given as names, e.g., "Down Arrow".  Print-
		 able 7-bit ASCII codes are given as-is, and hexadecimal val-
		 ues 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 environ-
	      ment 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 speci-
	      fied, 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, for-
	      mat 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 spec-
	      ified 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,
	      emacs, etc.)

       -emacskeys
	      enable emacs-like key movement.

       -enable_scrollback
	      toggles  compatibility  with communication programs’ scrollback
	      keys (may be incompatible with some curses packages).

	      define a file where Lynx will report HTTP access codes.

       -exec  enable local program execution (normally not configured).

       -fileversions
	      include all versions of files in local VMS directory  listings.

       -find_leaks
	      toggle  memory  leak-checking.   Normally this is not compiled-
	      into 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).

	      listonly hidden links are shown only on L)ist screens and list-
	      ings  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.

	      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 cor-
	      ner but will instead be positioned at the	 start	of  the	 cur-
	      rently  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 dis-
	      abled,  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 for-
	      matted text.

       -stack_dump
	      disable SIGINT cleanup handler

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

       -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.

       -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 com-
       mands.
       o Type "K" for a complete list of the current key-stroke command	 map-
       pings.

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 vari-
			   able 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.

       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 configu-
			   ration 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 "Infor-
			   mation 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 vari-
			   able 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  "Infor-
			   mation 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	vari-
			   able	 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 deter-
			   mine 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 environ-
			   ment).  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 configu-
       ration file.  See the lynx.cfg file, and the (draft) CGI 1.1  Specifi-
       cation  <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	 set-
       tings:

       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 cata-
			   log 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, lim-
			   its	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
       platform 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
       subject", 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 ver-
       sions 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 University 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  indirectly (through inspiration and development of other
       systems).
