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 .I Lynx run on UNIX and VMS. .PP .I Lynx can be used to access information on the World Wide Web, or to build information systems intended primarily for local access. For example, .I Lynx has been used to build several Campus Wide Information Systems (CWIS). In addition, .I Lynx can be used to build systems isolated within a single LAN. .SH OPTIONS At start up, \fILynx\fR will load any local file or remote URL specified at the command line. For help with URLs, press \fB"?"\fR or \fB"h"\fR while running \fILynx\fR. Then follow the link titled, "Help on URL's." .PP .TP .B - If the only argument is '-', 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). .TP .B -anonymous used to specify the anonymous account. .TP .B -ascii disable kanji code translation when Japanese mode is on. .TP .B -auth\fR=\fIID\fR:\fIPASSWD set authorization ID and password for protected documents at startup. .TP .B -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. .TP .B -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. .TP .B -cache\fR=\fINUMBER set the NUMBER of documents cached in memory. The default is 10. .TP .B -case enable case-sensitive string searching. .TP .B -cfg\fR=\fIFILENAME specifies a Lynx configuration file other than the default lynx.cfg. .TP .B -child exit on left-arrow in startfile, and disable save to disk. .TP .B -crawl with -traversal, output each page to a file. with -dump, format output as with -traversal, but to stdout. .TP .B -display\fR=\fIDISPLAY set the display variable for X rexeced programs. .TP .B -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.w3.org/default.html. .TP .B -editor\fR=\fIEDITOR enable edit mode using the specified EDITOR. (vi, ed, emacs, etc.) .TP .B -emacskeys enable emacs-like key movement. .TP .B -enable_scrollback toggle compatibility with comm programs' scrollback keys (may be incompatible with some curses packages). .TP .B -error_file\fR=\fIFILE define a file where Lynx will report HTTP access codes. .TP .B -euc set kanji code to EUC when Japanese mode is on. .TP .B -fileversions include all versions of files in local VMS directory listings. .TP .B -force_html forces the first document to be interpreted as HTML. .TP .B -ftp disable ftp access. .TP .B -get_data send form data from stdin using GET method and dump results. .TP .B -head send a HEAD request for the mime headers. .TP .B -help print this Lynx command syntax usage message. .TP .B -historical toggles use of '>' or '-->' as a terminator for comments. .TP .B -homepage\fR=\fIURL set homepage separate from start page. .TP .B -image_links toggles inclusion of links for all images. .TP .B -index\fR=\fIURL set the default index file to the specified URL. .TP .B -jpn toggles Japanese character translations on or off. .TP .B -link\fR=\fNUMBER starting count for lnk#.dat files produced by -crawl. .TP .B -localhost disable URLs that point to remote hosts. .TP .B -locexec enable local program execution from local files only (if Lynx was compiled with local execution enabled). .TP .B -mime_header prints the MIME header of a fetched document along with its source. .TP .B -minimal toggles minimal versus valid comment parsing. .TP .B -nobrowse disable directory browsing. .TP .B -noexec disable local program execution. (DEFAULT) .TP .B -nolist disable the link list feature in dumps. .TP .B -nolog disable mailing of error messages to document owners. .TP .B -noprint disable print functions. .TP .B -noredir prevents automatic redirection and prints a message with a link to the new URL. .TP .B -nostatus disable the retrieval status messages. .TP .B -number_links force numbering of links. .TP .B -post_data send form data from stdin using POST method and dump results. .TP .B -print enable print functions. (default) .TP .B -pseudo_inlines toggles pseudo-ALTs for inlines with no ALT string. .TP .B -realm restricts access to URLs in the starting realm. .TP .B -reload flushes the cache on a proxy server (only the first document affected). .TP .B -restrictions\fR=\fI[option][,option][,option]... allows a list of services to be disabled selectively. The following list is printed if no options are specified. .I all - restricts all options. .I bookmark - disallow changing the location of the bookmark file. .I bookmark_exec - disallow execution links via the bookmark file. .I change_exec_perms - disallow changing the eXecute permission on files (but still allow it for directories) when local file management is enabled. .I 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. .I dired_support - disallow local file management. .I disk_save - disallow saving binary files to disk in the download menu. .I download - disallow downloaders in the download menu. .I editor - disallow editing. .I exec - disable execution scripts. .I exec_frozen - disallow the user from changing the local execution option. .I file_url - disallow using G)oto to go to file: URL's. .I goto - disable the 'g' (goto) command. .I inside_ftp - disallow ftps for people coming from inside your domain (utmp required for selectivity). .I inside_news - disallow USENET news posting for people coming from inside your domain (utmp required for selectivity). .I inside_rlogin - disallow rlogins for people coming from inside your domain (utmp required for selectivity). .I inside_telnet - disallow telnets for people coming from inside your domain (utmp required for selectivity). .I jump - disable the 'j' (jump) command. .I mail - disable mailing feature. .I news_post - disable USENET News posting. .I options_save - disallow saving options in .lynxrc. .I outside_ftp - disallow ftps for people coming from outside your domain (utmp required for selectivity). .I outside_news - disallow USENET news posting for people coming from outside your domain (utmp required for selectivity). .I outside_rlogin - disallow rlogins for people coming from outside your domain (utmp required for selectivity). .I outside_telnet - disallow telnets for people coming from outside your domain (utmp required for selectivity). .I print - disallow most print options. .I shell - disallow shell escapes and lynxexec or lynxprog G)oto's. .I suspend - disallow Unix Control-Z suspends with escape to shell. .I telnet_port - disallow specifying a port in telnet G)oto's. .TP .B -rlogin disable recognition of rlogin commands. .TP .B -selective require .www_browsable files to browse directories. .TP .B -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. .TP .B -sjis set kanji code to Shift JIS when Japanese mode is on. .TP .B -source works the same as dump but outputs HTML source instead of formatted text. .TP .B -telnet disable recognition of telnet commands. .TP .B -term\fR=\fITERM 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.) .TP .B -trace turns on WWW trace mode. .TP .B -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. .TP .B -underscore toggles use of _underline_ format in dumps. .TP .B -validate accept only http URLs (for validation).

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). .SH AUTHORS Lou Montulli, Garrett Blythe, Craig Lavender, Michael Grobe, Charles Rezac .br Academic Computing Services .br University of Kansas .br Lawrence, Kansas 66047 .PP Foteos Macrides .br Worcester Foundation .br Shrewsbury, Massachusetts 01545
