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
