Using Command Prompt Window

Using a command prompt window (Unix)

A command prompt window in Unix is referred to as a shell window (or terminal window). Here's an example of a Unix shell window.

When you open a shell window the current directory is usually your home directory. For navigating your file system from the shell window you can use the cd, ls, mkdir, and pwd commands. Here's a brief description of each of these commands along with some examples. For more complete information on each of these commands, you can issue the command man followed by the command name.

`cd /home/dcrew/progfun`	changes the current directory to `/home/dcrew/progfun`
`cd ..`	changes the current directory to the parent directory
