Your Turn

1. Review the following commands and write down what each does:

   1. pwd
   2. cd Desktop
   3. cd ~
   4. cd
   5. echo
   6. echo Hi there > greetings.txt
   7. cat greetings.txt
   8. mkdir /var/website
   9. !!

2. Explain the difference between cat, more, and less. Use the man command to explore the more and less commands. When would you use one command over another?

3. The history command will show you the recent commands you typed. Create a log for your notes of the commands by saving the result of the history command to a text file called history.txt.

4. The cal and ncal commands give you a small calendar right in your terminal. Explore both of these commands and then use each to display a calendar for two years in the future.
