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.

Pick keys from map

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: squeek

then

yq '.myMap |= pick(["hamster", "cat", "goat"])' sample.yml

will output

myMap:
  hamster: squeek
  cat: meow

Pick indices from array

Note that the order of the indices matches the pick order and non existent indices are skipped.
