DESCRIPTION

The gopher client is used to talk to gopher servers. Once you have started the gopher client, help on using it is available by pressing the "?"key.

The Internet Gopher is a distributed document delivery service. It allows a neophyte user to access various types of data residing on multiple hosts in a seamless fashion. This is accomplished by presenting the user a hierarchical arrangement of documents and by using a client-server communications model. The Internet Gopher Server accepts simple queries, and responds by sending the client a document.

The [hostname] of a gopher server may be specified at startup; if omitted, the default server for your site is used. You may also specify a URL (Uniform Resource Locator) for this argument.

The [Port_number] of the server host may be specified at startup; if omitted you will use the default port specified at your site. The more or less standard and accepted Gopher port number on the Internet is 70.

OPTIONS

-b starts the client on the bookmark page.

The next few options are for more advanced users who want to start at a location other than the default, or to set up special aliases or shell-scripts to point the gopher client to seperate places.

I -p " path" specify a specific selector string to send to the gopher server on startup.

I -T " type" let the client know what type of object the -p option is pointing at.

I -i " search term" tell the client what to search for in the object defined by the R "-p " and " -T 7" options.

I -t " title" set the title of the initial screen for the gopher client.

The last few options aren't really of interest to regular users, but are provided for system administrators who waht to provide a secure client, or who need to debug a client.

R -s " or " -S "secure mode" which means that you can't save or print the files that you browse. -s is for users without an account, while -S assumes the user has an account on this machine. One security feature is forced on, regardless of the state of these options, if the name of the user's shell ends in rsh; the 'O' (options) command is disabled so the user cannot select a shell as an application.

-r tells the client that its user is remote.

-D turns on the copius debugging output
