Remember, the power of the Linux environment is the command-line interaction with the operating system. These exercises will help you become familiar with the environment.

For each of the following commands, execute the command, show the resulting output, and describe what each one does:

1. cd
2. mkdir apache
3. cd APACHE
4. cd apache
5. pwd
6. cd ../../../../../../../etc

9. more passwd
