Suppose you are new to Unix and have just logged into a Unix system
and wanted to print the file README...

<ul><pre>
% print README
print: Command not found.

% display README
display: Command not found.

% list README
list: Command not found.

% type README
type: Command not found.
</pre></ul>

Ok, so you can't guess the command to use for printing a file.  You're
resourceful.  You've used computers before.  You aren't afraid to
explore...

<ul><pre>
% help print
help: Command not found.

% help
help: Command not found.

% info
Sorry, unable to find the node "Top" in the file "DIR".
info: Cannot find "DIR", anywhere along the search path of
".::/usr/local/info".

% ?
?: No match.

% information
information: Command not found.

% teach
teach: Command not found.

% learn
learn: Command not found.

% commands
commands: Command not found.

% please help me
please: Command not found.
</pre></ul>

Ok, if it is going to be such an unfriendly system, we're outta here...
<ul><pre>

% logoff
logoff: Command not found.

% quit
quit: Command not found.

% bye
bye: Command not found.

% end
end: Not in while/foreach.

% logout
There are stopped jobs.
</pre></ul>

It's time to recognize that resistance is futile.  You prepare to be assimilated...
