Pick
Filter a map by the specified list of keys. Map is returned with the key in the order of the pick list.
Similarly, filter an array by the specified list of indices.
Note that the order of the keys matches the pick order and non existent keys are skipped.
Given a sample.yml file of:
myMap:
cat: meow
dog: bark
thing: hamster
hamster: squeak
then
yq '.myMap |= pick(["hamster", "cat", "goat"])' sample.yml
will output
myMap:
hamster: squeak
cat: meow
Note that the order of the indices matches the pick order and non existent indices are skipped.
Given a sample.yml file of:
- cat
- leopard
- lion
then
yq 'pick([2, 0, 734, -5])' sample.yml
will output
- lion
- cat
