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. -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 -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:

       -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.

       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

       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.

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).
