About this Hands-on Lab

Bash scripting is an invaluable skill for a Linux system administrator. From writing quick scripts that automate simple tasks to writing complex scripts than can automatically deploy entirely new servers, scripting skills are integral to being a good SysAdmin. In this lab, we’ll modify an existing script to use regular expressions.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Modify the Backup Script to Add the Requested Regular Expression

Modify the provided backup script to use regular expressions to determine which files to copy.

Run the Script and Verify the Files Are Backed up as Requested

Mark the script as executable and run it, then verify that all files are backed up to the required directory.

Additional Resources

You work for Universe Incorporated. One of your users — cloud_user — has an already existing backup script. He's put in a request to modify the script to back up any file that includes the word "financial" or the username "adent" in the filename, rather than the current functionality that is to back up all files.

Once complete, ensure it runs and successfully backs up the required files.

If you get stuck, feel free to check out the solution video or the detailed instructions under each objective. Good luck!
