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

       -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

              enable emacs-like key movement.

       -enable_scrollback
              toggles compatibility with communication  programs'
              scrollback  keys  (may  be  incompatible  with some
              curses packages).

       -error_file=FILE
              define a file where Lynx will  report  HTTP  access
              codes.

       -exec  enable   local   program  execution  (normally  not
              configured).

       -fileversions
              include  all  versions  of  files  in   local   VMS
              directory listings.

       -find_leaks
              toggle  memory leak-checking.  Normally this is not
              compiled-into your executable, but when it  is,  it
              can be disabled for a session.

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

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

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

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

       -head  send a HEAD request for the mime headers.

       -help  print the Lynx command syntax usage message.

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

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

              listonly hidden  links  are  shown  only  on  L)ist
              screens and listings generated by -dump or from the
              P)rint menu, but appear separately at  the  end  of
              those lists.  This is the default behavior.

              ignore hidden links do not appear even in listings.

       -historical

       -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.

              turn  on  optional traces, which may result in very
              large trace files.   Logically  OR  the  values  to
              combine options:

              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.

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.

                           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

                           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.

       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

LYNX(1)                                                   LYNX(1)


                           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



                              Local                            19





LYNX(1)                                                   LYNX(1)


       REQUEST_METHOD

       SERVER_SOFTWARE

       Other environment  variables  are  not  inherited  by  the
       script, unless they are provided via a LYNXCGI_ENVIRONMENT
       statement in the configuration  file.   See  the  lynx.cfg
       file,    and    the    (draft)   CGI   1.1   Specification
       <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The CGI Specification, and other associated documentation,
       should be consulted for general information on CGI  script
       programming.

NATIVE LANGUAGE SUPPORT
       If  configured and installed with Native Language Support,
       Lynx will display status and other messages in your  local
       language.    See   the   file   ABOUT_NLS  in  the  source
       distribution,  or  at  your  local  GNU  site,  for   more
       information about internationalization.

       The  following  environment variables may be used to alter
       default settings:

       LANG                This variable, if set,  will  override
                           the  default  message language.  It is
                           an ISO 639 two-letter code identifying
                           the  language.  Language codes are NOT
                           the same as the country codes given in
                           ISO 3166.

       LANGUAGE            This  variable,  if set, will override
                           the default message language.  This is
                           a   GNU   extension  that  has  higher
                           priority  for  setting   the   message
                           catalog than LANG or LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These  variables,  if set, specify the
                           notion of native  language  formatting
                           style.  They are POSIXly correct.

       LINGUAS             This   variable,   if   set  prior  to
                           configuration,  limits  the  installed
                           languages to specific values.  It is a
                           space-separated  list  of   two-letter
                           codes.  Currently, it is hard-coded to
                           a wish list.

       NLSPATH             This variable, if set, is used as  the
                           path prefix for message catalogs.

       Note  that  man page availability and section numbering is
       somewhat platform dependent, and may vary from  the  above
       references.

       A  section  shown as (GNU), is intended to denote that the
       topic may be available via an info page, instead of a  man
       page  (i.e.,  try  "info  subject",  rather than "man sub-
       ject").

       A section shown as (?) denotes that documentation  on  the
       topic exists, but is not part of an established documenta-
       tion retrieval system (see the distribution files  associ-
       ated  with the topic, or contact your System Administrator
       for further information).

ACKNOWLEDGMENTS
       Lynx has incorporated code from a variety of sources along
       the way.  The earliest versions of Lynx included code from
       Earl Fogel of Computing  Services  at  the  University  of
       Saskatchewan,  who  implemented HYPERREZ in the Unix 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-
