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 integrate bash variables into an existing backup script.
Successfully complete this lab by achieving the following learning objectives:
- Modify the Backup Script to Use Variables That Would Allow Other Users to Successfully Run the Script
Ensure that any references to "cloud_user" are replaced by a variable that will reference the username of the user running the script.
- Add a Parameter to Determine the Name of the Log File
Add a variable for the log file that will be populated by a parameter passed on the command line.
- Run the Script in Each User’s Home Directory to Ensure That It Works
Mark the script as executable and run it, then verify that all files are backed up to the required directory.
