"Saskatoon": counting IPs. - solution

[16monav-sys]

awk '{print $1}' "$LOG" | sort | uniq -c | sort -nr | awk 'NR==1 {print $2}' > "$OUT"
while LOG is for log file and OUT for highestip.txt.

how its wrong?

@16monav-sys The issue is that your pipeline never sorts before uniq -c, so uniq -c is only counting consecutive duplicate IPs, not total occurrences across the file. You can look at the Clues in the scenario for the solution with 482 occurrences, while yours has 273
