    man2html - format a manual page in html


    man2html [options] [file]  


    man2html converts a manual page as found in file (or stdin, in case no file argument, or the argument "-", is given) from man-style nroff into html, and prints the result on stdout. It does support tbl but does not know about eqn. The exit status is 0. If something goes wrong, an error page is printed on stdout.

    This can be used as a stand-alone utility, but is mainly intended as an auxiliary, to enable users to browse their man pages using a html browser like lynx(1), xmosaic(1) or netscape(1).

    The main part of man2html is the troff-to-html engine written by Richard Verhoeven ( It adds hyperlinks for the following constructs:


    (The first of these can be tuned by options - see below.) No lookup is done - the links generated need not exist. Also an index with internal hyperlinks to the various sections is generated, so that it is easier to find one's way in large man pages like bash(1).



    When reading from stdin, it is not always clear how to do .so expansion. The -D option allows a script to define the working directory.

    -D pathname
    Strip the last two parts from the pathname, and do a chdir(dir) before starting the conversion.

    The -E option allows the easy generation of error messages from a cgi script.

    -E string
    Output an error page containing the given error message.

    The general form of a hyperlink generated for a man page reference is


    with a default as shown above. The parts of this hyperlink are set using the various options.

    Set method:cgipath to http://localhost. This is the default.
    -H host[.domain][:port]
    Set method:cgipath to http://host.domain:port.
    Set method:cgipath to lynxcgi:/home/httpd.
    -L dir
    Set method:cgipath to lynxcgi:dir.
    -M man2htmlpath
    Set the man2htmlpath to use. The default is /cgi-bin/man/man2html.
    Set separator to '/'.
    Set separator to '?'. This is the default.
    Use relative html paths, instead of cgi-bin paths.

    On a machine without running httpd, one can use lynx to browse the man pages, using the lynxcgi method. When some http daemon is running, lynx, or any other browser, can be used to browse the man pages, using the http method. The option -l (for `lynxcgi') selects the former behaviour. With it, the default cgipath is /home/httpd.

    In general, a cgi script can be called by


    and the environment variables PATH_INFO and QUERY_STRING will be set to <more_path> and <query>, respectively. Since lynxcgi does not handle the PATH_INFO part, we generate hyperlinks with `?' as a separator by default. The option -p (for `path') selects '/' as a separator, while the option -q (for `query') selects '?' as a separator.

    The option -H host will specify the host to use (instead of localhost). A cgi script could use

    man2html -H $SERVER_NAME

    if the variable SERVER_NAME is set. This would allow your machine to act as a server and export man pages.



    There are many heuristics. The output will not always be perfect. The lynxcgi method will not work if lynx was compiled without selecting support for it. There may be problems with security.
