I will review this file when your lab is submitted. 11.

Blackboard will allow you to upload multiple files (the screen captures and gzipped tar archive). You will need to use your SFTP program to first download this tar and gzipped file to your local computer so you can upload it through Blackboard along with the screen captures. Fix MeWithSed.txt.
