I found an alternative solution there for Task #3:
cut flightdelays.csv -d',' -f18 | sort | uniq -c | sort -n -r | head -3

It’s not a big difference from your code, just I rotated top 3 destination airports from lowest to highest :).

Best regards,
Tamás

It’d better to use this command to get rid of the garbage ‘NA’ and then count the number of airports:
cut -d’,’ -f18 flightdelays.csv | grep -v ‘Dest’ | grep -v ‘NA’ | sort -u | wc -l
which gives 307 .
Cheers

This is because grep removes the line after the count. Check it out:
cut -d',' -f15 flightdelays.csv | head | sort -n
ArrDelay is on line 3
cut -d',' -f15 flightdelays.csv | head | sort -n | grep -v -n 'ArrDelay'

Related: When I was trying to solve the question alone I searched for a way to remove the first line and got tail -n +2 filename.ext , works great, I think it’s a better option to remove headers.

Thanks for the great content Tomi!
