2. What am I supposed to know?
It is assumed that you:
- have an account on bohr, one of the central servers at Brock;
- know a little bit about Unix or Linux, its file and command structure, and
some editor like vi or pico. Linux is a version of Unix
meant for machines that use an Intel-compatible processor or CPU, including
the current Apple desktop and laptop computers.
- can use a mouse, are familiar with the concept of windows, and
with the process of clicking and dragging to manipulate windows
(closing, resizing, etc.).
If you feel that the above does not apply to you, let your
instructor know now. Otherwise, you may want to start a separate
shell window right
away. In this window, you can then run physica and try different commands as we
go along.
Briefly about the notation used in this document:
this font is used to indicate a ``computer word'', i.e. a
prompt or a message from a program, while something
you need to type in shows up like this.
In the latter case, a carriage return is implied at the
end of every line of input.
