1 LYNX
2 Name
       lynx  -  a general purpose distributed information browser
       for the World Wide Web

2 Synopsis
       lynx [options] [path or URL]

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

2 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.

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

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

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

       -accept_all_cookies
              accept all cookies.

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

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

       -assume_local_charset=MIMEname
              charset assumed for local files.

       -assume_unrec_charset=MIMEname
              use this instead of unrecognized charsets.

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

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

       -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
              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.

       -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.

       -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.

       -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.

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

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

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

              lynx -dump http://www.trill-home.com/lynx.html

       -editor=EDITOR

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

       -force_html

              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.

       -selective
              require .www_browsable files to browse directories.

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

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

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

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

              double-quotes and tags.

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

       -stack_dump
              disable SIGINT cleanup handler

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

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

       -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.

       -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
              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 -dumping or -crawling
              (like 'man' does)

2 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.

2 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_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 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_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.

2 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.

2 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).

2 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).
