INTRODUCTION – Final Project

LOG ANALYSIS USING REGULAR EXPRESSIONS

1. What will the following command return?

grep "ERROR Tried to add information to closed ticket" syslog.log

2. You can reverse the order of the sort using the reverse parameter. What type of argument does the reverse parameter take? 

3. What is the primary advantage of using regular expressions when writing automation scripts to process a system log and generate reports from log files? 

4. While you were working with the log file named syslog.log, what command did you use to view the file? 

5. What would you expect the command grep “ERROR Ticket doesn’t exist” syslog.log to return?

6. What is the Python module used to perform similar tasks to the Unix command grep for filtering log data? 

7. Evaluate the following problem statement: “I want to create a script to sort files.” What’s missing? 

8. Which of the following commands would convert a csv file named error_message.csv into HTML file named errors.html? 

9. Once you’ve understood the problem statement, what should be the second step for your coding project?

10. Which task can you accomplish by using regular expressions in log analysis? 

11. Complete the sentence for the following Python regular expression: To match a string stored in a line variable, we use the search() method by defining a_____.

12. When sorting this dictionary:

fruit = {"oranges": 3, "apples": 5, "bananas": 7, "peaches": 2}
What will the following line of code return?
	sorted(fruit.items(), key=operator.itemgetter(1))

13. Which of the following is a potential pitfall of automation in Python? 

14. Why are regular expressions useful? 

15. What is the method used to match a string stored in a line variable by defining a pattern? 

16. What is the primary purpose of using regular expressions in log analysis? 

17. Which of the following is true about using regular expressions? 

18. Why do you need to know how to write automation scripts that process a system log and generate reports from the log files? 

19. What would you expect the command grep “ERROR” syslog.log to return?

20. Which argument can be used with the sorted() function to sort a dictionary’s items based on their values in descending order? 

21. If there is no csv file named user_emails.csv, what will the command nano user_emails.csv return? 

22. What will the following command return?

grep "ERROR" syslog.log

23. When sorting this dictionary:

fruit = {"oranges": 3, "apples": 5, "bananas": 4, "pears": 2}

What will the following line of code return?

sorted(fruit.items(), key=operator.itemgetter(1))

24. When sorting this dictionary:

fruit = {"oranges": 3, "apples": 5, "bananas": 7, "pears": 2}

What will the following line of code return?

sorted(fruit.items(), key=operator.itemgetter(1))

25. What syntax would you use to enlist all the ERROR messages of a specific kind?

26. In Python, regular expressions are typically handled using which module? 

27. How does the sorted() function sort items in a Python dictionary? 

28. If there is no python script named ticky_check.py, what will the command nano ticky_check.py return?
