LYNX(l)

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 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 and VMS.

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 URL's."

    allows a list of services to be disabled selectively. The following list is printed if no options are specified. all - restricts all options. bookmark - disallow changing the location of the bookmark file. default - same as command line option -anonymous. Disables default services for anonymous users. Currently set to all restricted except for: inside_telnet, outside_telnet, inside_news, inside_ftp, outside_ftp, inside_rlogin, outside_rlogin, jump, mail and goto. Defaults are setable within userdefs.h. disk_save - disallow saving binary files to disk in the download menu. download - disallow downloaders in the download menu. editor - disallow editing. exec - disable execution scripts. exec_frozen - disallow the user from changing the local execution option. file_url - disallow using G)oto to go to file: URL's. goto - disable the 'g' (goto) command. inside_ftp - disallow ftps for people coming from inside your domain (utmp required for selectivity). inside_news - disallow USENET news posting for people coming from inside your domain (utmp required for selectivity). inside_rlogin - disallow rlogins for people coming from inside your domain (utmp required for selectivity). inside_telnet - disallow telnets for people coming from inside your domain (utmp required for selectivity). jump - disable the 'j' (jump) command. mail - disable mailing feature. news_post - disable USENET News posting. options_save - disallow saving options in .lynxrc. outside_ftp - disallow ftps for people coming from outside your domain (utmp required for selectivity). outside_news - disallow USENET news posting for people coming from outside your domain (utmp required for selectivity). outside_rlogin - disallow rlogins for people coming from outside your domain (utmp required for selectivity). outside_telnet - disallow telnets for people coming from outside your domain (utmp required for selectivity). print - disallow most print options. shell - disallow shell escapes and lynxexec G)oto's. suspend - disallow Unix Control-Z suspends with escape to shell.

-rlogin
    disable recognition of rlogin commands.

-selective
    require .www_browsable files to browse directories.

-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, and the default configuration can be changed in userdefs.h.

-source
    works the same as dump but outputs HTML source instead of formatted text.

-telnet
    disable recognition of telnet commands.

-term=TERM
    tell Lynx what terminal type to assume its 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.)

-trace
    turns on WWW trace mode.

-version
    print version information.

-vikeys
    enable vi-like key movement.

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.

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 UN*X 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 UN*X 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 to everyone on the net who has contributed to Lynx's development either directly (through comments or bug reports) or indirectly (through inspiration and development of other systems).
