LYNX

NAME

SYNOPSIS

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

DESCRIPTION

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

-

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).

-anonymous

used to specify the anonymous account.

-assume_charset=ID:MIMEname

charset for documents that don't specify it.

-assume_local_charset=ID:MIMEname

charset assumed for local files.

-assume_unrec_charset=ID: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.

-blink

forces high intensity bg colors for color mode, if available and supported by the terminal. Lynx needs to be compiled with the slang library for this flag.

-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.

-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.

-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. A saved show_color=always setting found in a .lynxrc file at startup has the same effect. A saved show_color=always found in .lynxrc on startup is overridden by this flag.

-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.

-display=DISPLAY

set the display variable for X rexec-ed programs.

-dump

dumps the formatted output of the default document or one specified on the command line to standard out. This can be used in the following way: lynx -dump http://www.crl.com/~subir/lynx.html.

-editor=EDITOR

enable edit mode using the specified EDITOR. (vi, ed, emacs, etc.)

-emacskeys

enable emacs-like key movement.

-enable_scrollback

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

-error_file=FILE

define a file where Lynx will report HTTP access codes.

-fileversions

include all versions of files in local VMS directory listings.

-force_html

forces the first document to be interpreted as HTML.

-force_secure

toggles forcing of the secure flag for SSL cookies.

-from

toggles transmissions of From headers.

-ftp

disable ftp access.

-get_data

send form data from stdin using GET method and dump results.

-head

send a HEAD request for the mime headers.

-help

print this 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

toggles use of '>' or '-->' as a terminator for comments.

-homepage=URL

set homepage separate from start page.

-image_links

toggles inclusion of links for all images.

-index=URL

set the default index file to the specified URL.

-ismap

toggles inclusion of ISMAP links when client-side MAPs are present.

-link=NUMBER

starting count for lnk#.dat files produced by -crawl.

-localhost

disable URLs that point to remote hosts.

-locexec

enable local program execution from local files only (if Lynx was compiled with local execution enabled).

-mime_header

prints the MIME header of a fetched document along with its source.

-minimal

toggles minimal versus valid comment parsing.

-newschunksize=NUMBER

number of articles in chunked news listings.

-newsmaxchunk=NUMBER

maximum news articles in listings before chunking.

-nobrowse

disable directory browsing.

-nocc

disable Cc: prompts for self copies of mailings. Note that this does not disable any CCs which are incorporated within a mailto URL or form ACTION.

-nocolor

force color mode off, overriding terminal capabilities and any -color flags, COLORTERM variable, and saved .lynxrc settings.

-noexec

disable local program execution. (DEFAULT)

-nofilereferer

disable transmissions of Referer headers for file URLs.

-nolist

disable the link list feature in dumps.

-nolog

disable mailing of error messages to document owners.

-nopause

disable forced pauses for statusline messages.

-noprint

disable print functions.

-noredir

prevents automatic redirection and prints a message with a link to the new URL.

-noreferer

disable transmissions of Referer headers.

-nosocks

disable SOCKS proxy usage by a SOCKSified Lynx.

-nostatus

-number_links

-pauth=ID:PASSWD

-show_cursor

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.

-startfile_ok

allow non-http startfile and homepage with -validate.

-tagsoup

initialize parser, using Tag Soup DTD rather than SortaSGML.

toggles use of a Lynx Trace Log for the current session.

-trace

turns on WWW trace mode.
