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-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." If more than one local file or remote URL is listed on the command line, Lynx will open only the last interactively. All of the names (local files and remote URLs) are added to the G)oto history. 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). Lynx provides many command-line options. Some options require a value (string, number or keyword). These are noted in the reference below. The other options set boolean values in the program. There are three types of boolean options: set, unset and toggle. If no option value is given, these have the obvious meaning: set (to true), unset (to false), or toggle (between true/false). For any of these, an explicit value can be given in different forms to allow for operating system constraints, e.g., -center:off -center=off -center- Lynx recognizes "1", "+", "on" and "true" for true values, and "0", "-", "off" and "false" for false values. Other option-values are ignored. The default boolean, number and string option values that are compiled into lynx are displayed in the help-message provided by lynx -help. Some of those may differ according to how lynx was built; see the help message itself for these values. The -help option is processed before any option, including those that control reading from the lynx.cfg file. Therefore runtime configuration values are not reflected in the help-message. - If the argument is only '-', then Lynx expects to receive the arguments from the standard input. 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, i.e., files which lynx creates such as internal pages for the options menu. -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 the standard output. -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 
 when -dump'ing and -crawl'ing,
	      mark wrapped lines in interactive session.

       -dump  dumps  the  formatted  output  of  the default document or those
	      specified on  the  command  line	to  standard  output.	Unlike
	      interactive mode, all documents are processed.  This can be used
	      in the following way:

	      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.

       -historical

	      people  coming  from  outside  your  domain  (utmp  required for
	      selectivity).   This  restriction  applies  to  "news",  "nntp",
	      "newspost",   and   "newsreply"	URLs,	but  not  to  "snews",
	      "snewspost", or "snewsreply" in case they are supported.

	      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.  For example

	      lynx -source . >foo.html

	      generates   HTML	 source  listing  the  files  in  the  current
	      directory.  Each file is marked  by  an  HREF  relative  to  the
	      parent  directory.   Add	a  trailing  slash  to make the HREF's
	      relative to the current directory:

	      lynx -source ./ >foo.html

       -stack_dump
	      disable SIGINT cleanup handler

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

       -stderr
	      When dumping a document using -dump or  -source,	Lynx  normally
	      does  not  display  alert  (error)  messages that you see on the
	      screen in the status line.  Use the -stderr option to tell  Lynx
	      to write these messages to the standard error.

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

       -syslog=text
	      information for syslog call.

       -syslog-urls
	      log requested URLs with syslog.

       -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

	  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 
       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).
