You'll web ecommerce brentwood find these noted

7.2 YOUR FRIEND web ecommerce brentwood ARCHIE
How do you find a file you want, though?
Until a few years ago, this could be quite the pain -- there was
no master directory to tell you where a given file might be stored on
the Net. Who'd brentwood domain hosting want to slog through hundreds of file libraries looking
for something?
Alan Emtage, Bill Heelan and Peter Deutsch, students at McGill
University in Montreal, asked the same question.
Unlike the weather,
though, they did something about it.
They created a database system, called archie, that would
periodically call web ecommerce brentwood up file libraries and basically find out what they had
available. In turn, anybody could dial into archie, type in a file name,
and see where on the Net it was available. Archie currently catalogs
close to 1,000 file libraries around the world.
Today, there are three ways to ask archie to find a file for you:
through telnet, "client" Archie program on your own web ecommerce brentwood host system or e-
mail. All three methods let you type in a full or partial file name and
will tell you where on the Net web ecommerce brentwood it's stored.
If you have web ecommerce brentwood access to telnet, you can telnet to one of brentwood ecommerce consultants the following
addresses: archie.mcgill.ca; archie.sura.net; archie.unl.edu;
archie.ans.net; or archie.rutgers.edu. If asked for a log-in name, type
archie
and hit enter.
When you connect, the key command is prog, which you use in this
form:
prog filename
followed by enter, where "filename" is the program or file you're
looking for. If you're unsure of a file's complete name, try typing in
part of the name. For example, "PKZIP" will work as well as
"PKZIP204.EXE." The system does not support DOS or Unix wildcards.
If you ask archie to look for "PKZIP*," it will tell you it couldn't
find anything by that name.
One thing to keep in mind is that a file is
not necessarily the same as a program -- it could also be a document.
This means you can use archie to search for, say, everything online
related to the Beetles, as well as computer programs and graphics files.
A number of Net sites now have their own archie programs that
take your request for information and pass it onto the nearest archie
database -- ask your system administrator if she has it online.
These
"client" programs seem to provide information a lot more quickly than the
actual archie itself! If it is available, at your host web ecommerce brentwood system's command
line, type
archie -s filename
where filename is the program or document you're looking for, and hit
enter. The -s tells the program to ignore case in a file name and lets
you search for partial matches. You might actually want to type it this
way:
archie -s filename|more
