simulate a quiz:
https://ictgithub.senecacollege.cacom/ULI101/labs/~murray.saulraw/uli101main/uli101_week2_practice.docx
Your instructor may take-up these questions during class. It is up to the student to attend classes in order to obtain the answers to the following questions. Your instructor will NOT provide these answers in any other form (eg. e-mail, etc).
# Write a Linux command to display unique occurrences of consecutive lines in a file called '''practice/customers.txt'''
# Create a '''table''' listing each Linux command, useful options that are displayed near the top of this tutorial labelled: '''Tutorial Reference Material'''
