Awk: Associative Arrays (Counting)
MediumSed & Awk5-10 minThe brief
/root/work/access.log lists a client IP in column 1 per request.
Produce a per-IP request count into /root/work/out.txt: one 'IP count' line per unique IP (the IP, whitespace, then its request count — e.g. '192.0.2.10 4'), SORTED by IP. Plain sort order and numeric IP order (sort -V) are both accepted.
Grading compares against that sorted tally.
What you'll do
- Count the requests per unique client IP
- Emit one 'IP count' line per IP, sorted by IP, to /root/work/out.txt
Hands-on lab: you work on a real Linux box in your browser, graded on the machine's actual state.
