LYNX

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 termi-
nals, 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 iso-
lated 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."

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 com-
mand 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 -restric-
tions.

-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 is 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 speci-
fied 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 immedi-
ately.

key the character value, in printable form. Cursor and other
special keys are given as names, e.g., "Down Arrow". Print-
able 7-bit ASCII codes are given as-is, and hexadecimal val-
ues 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 environ-
ment variable. (If color support is instead provided by a
color-capable curses library like ncurses, Lynx relies com-
pletely on the terminal description to determine whether color
mode is possible, and this flag is not needed and thus unavail-
able.) 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 speci-
fied, 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, for-
mat 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 spec-
              ified on the command line to standard output.  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.

       -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).

       -force_html
              forces the first document to be interpreted as HTML.

       -force_secure
              toggles forcing of the secure flag for SSL cookies.

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

              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 num-
              bered together with other links in the sequence of their occur-
              rence in the document.

              listonly hidden links are shown only on L)ist screens and list-
              ings 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.

              rently 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 dis-
              abled, 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

              matted text.

       -stack_dump
              disable SIGINT cleanup handler

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

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

       -syslog=text
              information for syslog call.

       -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.

       -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  com-
       mands.
       o  Type "K" for a complete list of the current key-stroke command map-
       pings.

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  vari-
                           able  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  configu-
                           ration 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 "Infor-
                           mation 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  vari-
                           able  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 "Infor-
                           mation 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 vari-
                           able 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  deter-
                           mine  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  environ-
                           ment).   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  configu-
       ration  file.  See the lynx.cfg file, and the (draft) CGI 1.1 Specifi-
       cation    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 set-
       tings:

       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  cata-
                           log 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, lim-
                           its 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.
