Find files containing multiple documents

[planeiii-te]

I've tried several things like select(document_index > 1) or ([.] | length) > 1, but I haven't been able to crack this one.

I want to run yq "$expression" **/*.yaml and have it return a list of files that contain multiple documents, but I cannot figure out which expression to use. Any help would be appreciated.

yq -e 'select(documentIndex == 1)' filename.yaml

That will return an error if the second document doesn't exist (which means there's only one document).

Use that with something like find to get the matches:

find examples/data*.yaml -exec sh -c "yq -e 'select(documentIndex == 1)' {} 2>/dev/null 1>/dev/null  && echo '- {}'" \;
