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. -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 stdout. -curses_pads toggles the use of curses "pad" feature which supports left/right scrolling of the display. -debug_partial separate incremental display stages with MessageSecs delay -delay add DebugSecs delay after each progress-message -display=DISPLAY set the display variable for X rexec-ed programs. -display_charset=MIMEname set the charset for the terminal output. -dont_wrap_pre inhibit wrapping of text in 
  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:

       -telnet
              disable recognition of telnet commands.

       -term=TERM
              tell  Lynx  what  terminal  type  to  assume  it is
              talking  to.   (This  may  be  useful  for   remote
              execution,  when,  for  example, Lynx connects to a
              remote TCP/IP port that starts a  script  that,  in
              turn, starts another Lynx process.)

       -timeout=N
              For  win32,  sets the network read-timeout, where N
              is given in seconds.

       -tlog  toggles between using a Lynx Trace Log  and  stderr
              for trace output from the session.

       -tna   turns on "Textfields Need Activation" mode.

       -trace turns  on  Lynx  trace  mode.  Destination of trace
              output depends on -tlog.

       -trace_mask=value
              turn on optional traces, which may result  in  very
              large  trace  files.   Logically  OR  the values to
              combine options:
              1=SGML character parsing states
              2=color-style
              4=TRST (table layout)
              8=config (lynx.cfg and .lynxrc contents)
              16=binary string copy/append,  used  in  form  data
              construction.

       -traversal
              traverse  all  http  links  derived from startfile.
              When used with -crawl, each link that  begins  with
              the  same  string as startfile is output to a file,
              intended for indexing.  See CRAWL.announce for more
              information.

       trim_input_fields
              trim input text/textarea fields in forms.

       -underscore
              toggles use of _underline_ format in dumps.

       -use_mouse
              turn  on mouse support, if available.  Clicking the
              left mouse button on a link traverses it.  Clicking
              the right mouse button pops back.  Click on the top
              line to scroll up.  Click on  the  bottom  line  to
              scroll  down.   The  first few positions in the top
              and bottom line may  invoke  additional  functions.
              Lynx  must  be  compiled  with  ncurses or slang to
              support this feature.  If ncurses is used, clicking
              the  middle  mouse  button  pops  up a simple menu.
              Mouse clicks may only work reliably while  Lynx  is
              idle waiting for input.

       -useragent=Name
              set alternate Lynx User-Agent header.

       -validate
              accept  only  http URLs (for validation).  Complete
              security restrictions also are implemented.

       -verbose
              toggle [LINK], [IMAGE] and [INLINE]  comments  with
              filenames of these images.

       -version
              print version information.

       -vikeys
              enable vi-like key movement.

       -wdebug
              enable  Waterloo tcp/ip packet debug (print to watt
              debugfile).  This  applies  only  to  DOS  versions
              compiled with WATTCP or WATT-32.

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

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

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_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.

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

       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.

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).
