Sort contents of awk associative array element.

asort() on the other hand sorts on the contents of the array, and array contents can be strings OR numbers and so normal awk comparison rules apply - anything that looks like a number is treated like a number and the number 9 is less than the number 888 which in this case IMHO is the desired result. That's because asorti() sorts on array indices and all array indices are strings (even if they look like numbers) and alphabetically the first character of the string "9" IS higher than the first character of the string "888". Notice that asorti() treats "9" as a higher value than "888". In case anyone's wondering why I didn't just use the values we want to sort on as indices and then do an asorti() as that would have resulted in slightly briefer code, here's why: $ cat tst.awk Then asort()ing keys to get: keys = 777Īnd then looping through the keys array using it's elements as the indices to the vals array for re-populating the original array. It works by first converting this: a = "dog" FWIW, here's a workaround "sort_by()" function: $ cat tst.awk
