set difference - JQ: setdiff of two arrays -


if have object 2 arrays containing unique values in it

{"all":["a","b","c","abc"],"some":["b","c"]}

how can find .all - .some?

in case looking ["a","abc"]

@jeff mercado blew mind! didn't know array subtraction allowed...

echo -n '{"all":["a","b","c","abc"],"some":["b","c"]}' | jq '.all-.some'

yields

[   "a",   "abc" ]
