In general, how to sort(order by) multiple columns?
sort -k 1,3 is doing just that. eg, for input
Faroe Island 20 island
japan 19 test
japan 19 airline
Alpha Zulu 21 island
Alpha 121 island

Japan occurs twice in first column, so while sorting, 3rd column is considered and the output is:

Alpha 121 island
Alpha Zulu 21 island
Faroe Island 20 island
japan 19 airline
japan 19 test

isn't that what you wanted?
