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  in  the  third  pass  of  options-processing,  so any option which sets a value, as well as runtime configuration values are
       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 and associated print/mail options.

       -child_relaxed
              exit on left-arrow in startfile, but allow save to disk and associated print/mail options.

       -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 <pre> 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:

              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).

       -error_file=FILE
              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).

       -force_html
              forces the first document to be interpreted as HTML.

       -force_secure
              toggles forcing of the secure flag for SSL cookies.

              toggles whether the Options Menu is key-based or form-based.

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

       -get_data
              properly formatted data for a get form are read in from the standard input and passed to the form.  Input  is  terminated  by  a
              line that starts with '---'.

       -head  send a HEAD request for the mime headers.

       -help  print the Lynx command syntax usage message, and exit.

       -hiddenlinks=[option]
              control the display of hidden links.

              merge
                 hidden  links  show up as bracketed numbers and are numbered together with other links in the sequence of their occurrence in
                 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.

       -historical
              toggles use of '>' or '-->' as a terminator for comments.

              disable URLs that point to remote hosts.

       -locexec
              enable local program execution from local files only (if Lynx was compiled with local execution enabled).

       -lss=FILENAME
              specify  filename  containing  color-style  information.   The  default is lynx.lss.  If you give an empty filename, lynx uses a
              built-in monochrome scheme which imitates the non-color-style configuration.

       -mime_header
              prints the MIME header of a fetched document along with its source.

       -minimal
              toggles minimal versus valid comment parsing.

              suspend
                 disallow Unix Control-Z suspends with escape to shell.

              telnet_port
                 disallow specifying a port in telnet G)oto's.

              useragent
                 disallow modifications of the User-Agent header.

       -resubmit_posts
              toggles  forced resubmissions (no-cache) of forms with method 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.

       -session=FILENAME
              resumes from specified file on startup and saves session to that file on exit.

       -sessionin=FILENAME
              resumes session from specified file.

       -sessionout=FILENAME
              saves session to specified file.

       -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_cfg
              Print the configuration settings, e.g., as read from "lynx.cfg", and exit.

       -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  configuration (lynx.cfg, .lynxrc, .lynx-keymaps, mime.types and mailcap contents)

              16 binary string copy/append, used in form data construction.

              32 cookies

              64 character sets

              128
                 GridText parsing

              256
                 timing

       -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.

       -unique_urls
              check for duplicate link numbers in each page and corresponding lists, and reuse the original link number.

       -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, and exit.

       -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.  This is limited by the number of columns that Lynx could display,
              typically 1024 (the MAX_LINE symbol).

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

       -xhtml_parsing
              tells Lynx that it can ignore certain tags which have no content  in  an  XHTML  1.0  document.   For  example  "<p/>"  will  be
              discarded.

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_HELPFILE       If set, this variable overrides the compiled-in URL and configuration file URL for the Lynx help file.

       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 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 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 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 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).
