LYNX(1)                                                                LYNX(1)



NAME
       lynx - a general purpose distributed information browser for the World Wide Web

SYNOPSIS
       lynx [options] [path or URL]

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

DESCRIPTION
       Lynx  is  a  fully-featured  World  Wide  Web (WWW) client for users running cursor-addressable, character-cell
       display devices (e.g., vt100 terminals, vt100 emulators running on Windows 95/NT or Macintoshes, or  any  other
       "curses-oriented"  display).   It  will  display hypertext markup language (HTML) documents containing links to
       files residing on the local system, as well as files residing on remote  systems  running  Gopher,  HTTP,  FTP,
       WAIS, and NNTP servers.  Current versions of Lynx run on Unix, VMS, Windows 95/NT, 386DOS and OS/2 EMX.

       Lynx  can  be  used  to  access  information  on  the  World Wide Web, or to build information systems intended
       primarily for local access.  For example, Lynx has been used to build several Campus Wide  Information  Systems
       (CWIS).  In addition, Lynx can be used to build systems isolated within a single LAN.

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

       If more than one local file or remote URL is listed  on  the  command  line,  Lynx  will  open  only  the  last
       interactively.  All of the names (local files and remote URLs) are added to the G)oto history.

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

       Lynx  provides many command-line options.  Some options require a value (string, number or keyword).  These are
       noted in the reference below.  The other options set boolean values in the program.  There are three  types  of
       boolean  options:  set, unset and toggle.  If no option value is given, these have the obvious meaning: set (to
       true), unset (to false), or toggle (between true/false).  For any of these, an explicit value can be  given  in
       different forms to allow for operating system constraints, e.g.,
              -center:off
              -center=off
              -center-
       Lynx  recognizes  "1",  "+", "on" and "true" for true values, and "0", "-", "off" and "false" for false values.
       Other option-values are ignored.

       The default boolean, number and string option values that are compiled into lynx are  displayed  in  the  help-
       message provided by lynx -help.  Some of those may differ according to how lynx was built; see the help message
       itself for these values.  The -help option is processed before any option, including those that control reading
       from the lynx.cfg file.  Therefore runtime configuration values are not reflected in the help-message.

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

       -accept_all_cookies
              accept all cookies.

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

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

       -assume_local_charset=MIMEname
              charset  assumed  for local files, i.e., files which lynx creates such as internal pages for the options
              menu.

       -assume_unrec_charset=MIMEname
              use this instead of unrecognized charsets.

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

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

       -bibp=URL
              specify a local bibp server (default http://bibhost/).

       -blink forces  high  intensity  background  colors  for color mode, if available and supported by the terminal.
              This applies to the slang library (for a few terminal emulators), or to OS/2 EMX with ncurses.

       -book  use the bookmark page as the startfile.  The default or command line startfile is still set for the Main
              screen command, and will be used if the bookmark page is unavailable or blank.

       -buried_news
              toggles  scanning  of  news  articles  for  buried  references,  and  converts  them to news links.  Not
              recommended because email addresses enclosed in angle brackets will be converted to  false  news  links,
              and uuencoded messages can be trashed.

       -cache=NUMBER
              set the NUMBER of documents cached in memory.  The default is 10.

       -case  enable case-sensitive string searching.

       -center
              Toggle center alignment in HTML TABLE.

       -cfg=FILENAME
              specifies a Lynx configuration file other than the default lynx.cfg.

       -child exit on left-arrow in startfile, and disable save to disk.

       -cmd_log=FILENAME
              write keystroke commands and related information to the specified file.

       -cmd_script=FILENAME
              read  keystroke  commands  from  the  specified  file.   You can use the data written using the -cmd_log
              option.  Lynx will ignore other information which the command-logging may have written to  the  logfile.
              Each line of the command script contains either a comment beginning with "#", or a keyword:

            exit causes the script to stop, and forces Lynx to exit immediately.

            key  the  character  value,  in  printable  form.  Cursor and other special keys are given as names, e.g.,
                 "Down Arrow".  Printable 7-bit ASCII codes are given as-is, and hexadecimal  values  represent  other
                 8-bit codes.

            set  followed by a "name=value" allows one to override values set in the lynx.cfg file.

       -color forces  color mode on, if available.  Default color control sequences which work for many terminal types
              are assumed if the terminal capability description does not specify how to handle color.  Lynx needs  to
              be  compiled with the slang library for this flag, it is equivalent to setting the COLORTERM environment
              variable.  (If color support is instead provided by a color-capable curses library  like  ncurses,  Lynx
              relies completely on the terminal description to determine whether color mode is possible, and this flag
              is not needed and thus unavailable.)  A saved show_color=always setting  found  in  a  .lynxrc  file  at
              startup has the same effect.  A saved show_color=never found in .lynxrc on startup is overridden by this
              flag.

       -connect_timeout=N
              Sets the connection timeout, where N is given in seconds.

       -cookie_file=FILENAME
              specifies a file to use to read cookies.  If none is specified, the default value is ~/.lynx_cookies for
              most systems, but ~/cookies for MS-DOS.

       -cookie_save_file=FILENAME
              specifies  a  file  to  use  to store cookies.  If none is specified, the value given by -cookie_file is
              used.

       -cookies
              toggles handling of Set-Cookie headers.

       -core  toggles forced core dumps on fatal errors.  Turn this option off to ask Lynx to force a core dump  if  a
              fatal error occurs.

       -crawl with  -traversal,  output each page to a file.  with -dump, format output as with -traversal, but to the
              standard output.

       -curses_pads
              toggles the use of curses "pad" feature which supports left/right scrolling of the display.

       -debug_partial
              separate incremental display stages with MessageSecs delay

       -delay add DebugSecs delay after each progress-message

       -display=DISPLAY
              set the display variable for X rexec-ed programs.

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

       -dont_wrap_pre
              inhibit wrapping of text in <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.

              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.

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

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

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

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

              lynx -source . >foo.html

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

              lynx -source ./ >foo.html

       -stack_dump
              disable SIGINT cleanup handler

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

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

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

       -syslog=text
              information for syslog call.

       -syslog-urls
              log requested URLs with syslog.

       -tagsoup
              initialize parser, using Tag Soup DTD rather than SortaSGML.

       -telnet
              disable recognition of telnet commands.

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

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

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

       -tna   turns on "Textfields Need Activation" mode.

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

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

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

       trim_input_fields
              trim input text/textarea fields in forms.

       -underline_links
              toggles use of underline/bold attribute for links.

       -underscore
              toggles use of _underline_ format in dumps.

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

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

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

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

       -version
              print version information.

       -vikeys
              enable vi-like key movement.

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

       -width=NUMBER
              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)

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_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.

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  Uni-
       versity  of Kansas in the summer of 1994 through the release of v2.7.2, and to everyone on the net who has con-
       tributed to Lynx's development either directly  (through  patches,  comments  or  bug  reports)  or  indirectly
       (through inspiration and development of other systems).
