Use the pwd command to identify your location. 4. Use the cd / command to get to the root of your directory tree structure. 5. Use the cd ~ command to get back to your user’s home directory. 6. Take a screenshot (filename: screenshot_1) of the above activites. a. 7. Clear the shell with the clear command. Part 2: Learn about commands to get help. 1. Use the man ls command to review the ls command. Type q to quit. 2. Use the info ls command to review the ls command. Take note of how this is different from the man command. Type q to quit. 3.

Tesah Capers a. 5. Clear the shell with the clear command. Part 3: Learn about commands to navigate the directory tree structure while creating files and directories. 1. While in your user’s home directory, use the ls -1 / command to view the contents of the / directory. 2. Take a mental note of which direcotries are part of the Linux Filesystem Hierarchy Standard (FHS) and those that are not (refer back to learning materials for this module). 3. Use the mkdir test1 command to add a new directory in your home directory. 4. Use the cd command to change into the test1 directory that you just created in the previous step. 5. Use touch file1 to create a new empty file in the test1 directory. 6. Use the ls command with a single option (flag) to view the details of file1. (If you can’t remember which option is used to view the details, what can you do to view the available options for that command?). 7. Use rm file1 to delete it. 8. Exit the test1 directory and return to its parent directory. 9. Use rmdir test1 to delete it. 10. Use the mkdir command to add a directory named test2 in your home directory. 11. Copy the /etc/passwd file to the ~/test2 directory so a copy of /etc/passwd is stored at ~/test2/passwd.bak 12. Use one command to verufy that the copy of /etc/passwd was successfully made to ~/test2/passwd.bak while also indicating that it is not empty. The output of this command must consist of only two short lines. 13. Take a screenshot (filename: screenshot_3) of above activities.

Tesah Capers a. 14. Clear the shell with the clear command. PART 4: Learn about commands used to view the contents of files. 1. Use the cat command to review the contents of the ~/test2/passwd.bak 2. Take a screenshot (filename: screenshot_4) of the above activity.
