Labs to be performed in CentOS

Labs to be performed in CentOS. I don't need the labs done, I just need instructions on what commands are supposed to be performed each step.

STEP 1. Open a terminal window

STEP 2. Use the su command to switch to the root user. 

STEP 3. Back up the contents of the /etc/X11 directory into a tar file named /tmp/X11.tar. 

STEP 4. List the contents of the /tmp/X11.tar file, including details about the files (such as using verbose mode). 

STEP 5. Move to the /tmp directory.

STEP 6. Extract the contents of the X11.tar file into the current directory. 

STEP 7. Back up the contents of the /etc/X11 directory into a compressed tar file named /tmp/X11.tar.gz, using the gzip compression option

STEP 8. Execute the correct command so that you can see and compare the sizes of the two tar files.
