What Next?
Well done on finishing the Bash tutorial. Practise by automating something real: back up a folder every day, rename a set of photos, or check whether a website is online. Then learn cron to run your scripts on a schedule.
Keep your scripts safe: quote your variables, test them on sample files first, and add set -e at the top so a script stops at the first error.
