What Can You Do With Bash?

Knowing what Bash is used for makes it easier to stay motivated while learning the basics:

• File management — organize, rename, back up, and clean up files in bulk.
• Text processing — search logs, extract columns from CSV files, count and rank values, find and replace across many files.
• Automation scripts — set up a new computer, create project skeletons, run a sequence of build steps.
• Server administration — check disk space, restart services, rotate logs, monitor processes.
• Deployment and CI/CD — build, test, and deploy applications automatically.
• Scheduled jobs — run tasks every night or every hour with cron.
• Gluing tools together — call APIs with curl, process JSON with jq, and pass results between programs.

You'll build smaller versions of several of these in the project lessons at the end of each level.
