LYNX(1)							  LYNX(1)

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‐ori‐
       ented"  display).   It  will display hypertext markup lan‐
       guage (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 pro‐
	      cesses on most systems), especially when the  ‐auth
	      or ‐pauth options are used.

       ‐accept_all_cookies
	      accept all cookies.

LYNX(1)							  LYNX(1)

       ‐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.

       ‐blink forces  high  intensity background colors for color
	      mode, if available and supported by  the	terminal.
	      Lynx  needs  to  be compiled with the slang library
	      for this flag.

       ‐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 refer‐
	      ences, and converts them to news links.  Not recom‐
	      mended  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.

       ‐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.

2			      Local

LYNX(1)							  LYNX(1)

       ‐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  log‐
	      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 COL‐
	      ORTERM  environment variable.  (If color support is
	      instead provided by a color‐capable curses  library
	      like  ncurses, Lynx relies completely on the termi‐
	      nal 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.

       ‐cookies
	      toggles handling of Set‐Cookie headers.

       ‐cookie_file=FILENAME
	      specifies a file to use to store cookies.

       ‐connect_timeout=N
	      Sets  the	 connection  timeout, where N is given in
	      seconds.	This is not available under DOS (use  the
	      sockdelay parameter of WATTCP under DOS).

       ‐core  toggles forced core dumps on fatal errors.

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

       ‐debug_partial
	      incremental display stages with MessageSecs delay

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

       ‐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:

	      tion can be changed in userdefs.h or lynx.cfg.  The
	      command line switch toggles the default.

       ‐stack_dump
	      disable SIGINT cleanup handler

       ‐startfile_ok
	      allow non‐http startfile and homepage  with  ‐vali‐
	      date.

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

	      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 talk‐
	      ing 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.

       ‐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.

       ‐underscore
	      toggles use of _underline_ format in dumps.

       ‐use_mouse

	      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 sup‐
	      port  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 com‐
	      piled with WATTCP or WATT‐32.

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

       ‐with_backspaces
	      emit  backspaces in output if ‐dumping or ‐crawling
	      (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 hyper‐
       text 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 uti‐
       lizes 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.

12			      Local

LYNX(1)							  LYNX(1)

       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  ter‐
			   minal  is  forced  on at startup time.
			   The actual value assigned to the vari‐
			   able	 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_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 informa‐
			   tion.

       LYNX_TEMP_SPACE	   This variable, if set,  will	 override
			   the	default path prefix for temporary
			   files that was defined during  instal‐
			   lation,  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

			      Local			       13

LYNX(1)							  LYNX(1)

			   ORGANIZATION	 environment variable, if
			   it is also set (and, on UNIX, the con‐
			   tents 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 pro‐
			   tocol   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 PROTO‐
			   COL_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

14			      Local

LYNX(1)							  LYNX(1)

			   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  "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 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  "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 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 pro‐
			   gram,  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 sup‐
			   plied.

       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, how‐
			   ever, it is unset at startup time  (or

			      Local			       15

LYNX(1)							  LYNX(1)

			   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 speci‐
			   fied	 terminal type (for the Lynx exe‐
			   cution   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  envi‐
       ronment:

       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	distribu‐
       tion,  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 prior‐
			   ity	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 config‐
			   uration,  limits  the  installed  lan‐
			   guages 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 sub‐
       ject").

       A section shown as (?) denotes that documentation  on  the
       topic exists, but is not part of an established documenta‐
       tion retrieval system (see the distribution files  associ‐
       ated  with the topic, or contact your System 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 Computing	Services  at  the  University  of
       Saskatchewan,  who  implemented HYPERREZ in the Unix envi‐
       ronment.	  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 University of Kansas in the
       summer of 1994 through the release of v2.7.2, and  to  ev‐
       eryone  on  the net who has contributed to Lynx’s develop‐
       ment either directly (through patches, comments or bug re‐
       ports)  or indirectly (through inspiration and development
       of other systems).
