yq is a portable and lightweight command-line YAML processor. It can be likened to projects like jq (a command-line JSON processor) or sed but for YAML files. yq is able to do quite a number of things. It can deep read a YAML file with a given path expression, deeply compare YAML files, update a YAML file given a path expression or script file, and so much more. It can also merge several YAML files while offering plenty of options for overriding and appending.
yq is written in portable Go, allowing you to download a binary that's free of dependencies.
