You now have a subdirectory called project.  Of
course, you can make many subdirectories, or even
subdirectories of subdirectories.  This is a VERY
nice feature of UNIX.

$PROMPT$
Of course, there is no such directory, so
nowhere is a bad directory.  You
also get the same diagnostic if you try to
cd to someplace you aren't allowed to go.

acct/
You now know where the accounting software is
on  your UNIX system!  Use ls to tell you the
the names of the accounting packages.
Then just enter the name of the package
you wish to use to activate it.
