lynx − a general purpose distributed information browser for the World Wide Web
Lynx [options] [path or URL]
use "lynx -help" to display a complete list of current options.
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 PCs or Macs, 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, Windows95/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.
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 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). |
-accept_all_cookies
accept all cookies.
-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=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.
-cookie_file=FILENAME
specifies a file to use to store cookies.
|
-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. |
-debug_partial
incremental display stages with MessageSecs delay
-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.
|
-exec |
enable local program execution (normally not configured). |
-fileversions
include all versions of files in local VMS directory listings.
-force_html
forces the first document to be interpreted as HTML.

send a HEAD request for the mime headers. |
|||
|

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.

number of articles in chunked news listings.
-newsmaxchunk=NUMBER
maximum news articles in listings before chunking.

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 University of Kansas in the summer of 1994 through the release of v2.7.2, and to everyone on the net who has contributed to Lynx’s development either directly (through patches, comments or bug reports) or indirectly (through inspiration and development of other systems).
