Sed: In-Place Editing
EasySed & Awk3-5 minThe brief
A config file went out with a typo — 'databse' instead of 'database', in several places. Fix the file itself, not a copy of it.
Correct every 'databse' to 'database' in /root/work/app.conf.
Grading reads app.conf afterward: the typo must be gone everywhere and the correct spelling present.
What you'll do
- Correct the 'databse' typo to 'database' in the file itself, not a copy
- Leave no occurrence of the typo behind
Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
