Lesson 3: Assignment 1: Problem set 1Do all of the examples throughout Chapter 4 in Bash Cookbook by O'Reilly. To submit the homework, just leave a comment saying that you completed it and mention any problems you had or any cool things you learned. Don't print out your whole session history, it gets really long really fast. Do post code specific examples that you want to discuss. If you copy and paste any of your bash history, make sure that you don't post anything sensitive. Create dummy directories for working with files, don't post any passwords, etc. The assignment should take about 30 to 45 minutes to complete. Homework Submissions6 total
