cat charts.json | yq e -P ' .[].[] | select(.name =="mongo*") | (.name + "," + .version)'

merges f2.yml into f1.yml (inplace)

yq eval-all --inplace 'select(fileIndex == 0) * select(fileIndex == 1)' f1.yml f2.yml

you can merge into a file, piping from STDIN

cat somefile.yml | yq eval-all --inplace 'select(fileIndex == 0) * select(fileIndex == 1)' f1.yml -

yq eval-all 'select(fileIndex == 0) * select(fileIndex == 1)' a.yml b.yml

diff <(yq -P 'sort_keys(..)' -o=props a.yml) <(yq -P 'sort_keys(..)' -o=props b.yml)
