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",
- 1 - Formatted: April 23, 2024
LYNX(1) LYNX(1)
"-", "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 in the
third pass of options-processing, so any option which sets a value, as
well as runtime configuration values are 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
- 2 - Formatted: April 23, 2024

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 and
associated print/mail options.
-child_relaxed
exit on left-arrow in startfile, but allow save to disk and
associated print/mail options.
-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

LYNX(1) LYNX(1)
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

-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.

-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

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

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. This
is limited by the number of columns that Lynx could display,
typically 1024 (the MAX_LINE symbol).
-with_backspaces
emit backspaces in output if -dump'ing or -crawl'ing (like 'man'
does)
-xhtml_parsing
tells Lynx that it can ignore certain tags which have no content
in an XHTML 1.0 document. For example "<p/>" will be discarded.
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_HELPFILE If set, this variable overrides the compiled-in
URL and configuration file URL for the Lynx help
file.
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
- 16 - Formatted: April 23, 2024
LYNX(1) LYNX(1)
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.

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 subject").
A section shown as (?) denotes that documentation on the topic exists,
but is not part of an established documentation retrieval system (see
the distribution files associated with the topic, or contact your Sys-
tem 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 Comput-
ing Services at the University of Saskatchewan, who implemented HYPER-
REZ 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 ver-
sions 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).
