PART $3$: Learn about commands to navigate the directory tree structure while creating files and directories.

While in your user's home directory, use the ls $$l $/$ command to view the contents of the $/$ directory.

Take a mental note of which directories are part of the Linux Filesystem Hierarchy Standard $($FHS$)$ and those that are not $($refer back to the learning materials for this module$).$

Use the mkdir test$1$ command to add a new directory in your home directory.

Use the cd command to change into the test$1$ directory that you just created in the previous step.

Use touch file$1$ to create a new empty file in the test$1$ directory.

Use the ls command with a single option $($flag$)$ to view the details of file$1.($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?$)$

Use rm file$1$ to delete it$.$

Exit the test$1$ directory and return to its parent directory.

Use rmdir test$1$ to delete it$.$

Use the mkdir command to add a directory named test$2$ in your home directory.

Copy the $/$etc$/$passwd file to the ~$/$test$2$ directory so a copy of $/$etc$/$passwd is stored at ~$/$test$2/$passwd$.$bak

Use one command to verify that the copy of $/$etc$/$passwd was successfully made to ~$/$test$2/$passwd$.$bak while also indicating that it is not empty. The output of this command must consist of only two short lines.

Take a screenshot $($filename: screenshot$\_3)$ of the above activities.

Clear the shell with the clear command.
