Sed: Print a Line Range
EasySed & Awk3-5 minThe brief
You need just lines 10 through 20 of a log.
Extract those lines from /root/work/app.log into /root/work/out.txt.
Grading checks you got those 11 lines, in order, with no duplicates — a common first attempt emits every line twice.
What you'll do
- Extract exactly lines 10-20, in order
- Save the 11 lines to /root/work/out.txt with no duplicates
Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
