pip install yq
Before using yq, you also have to install its dependency, jq. See the jq installation instructions for details and directions specific to your platform.
yq's mode of operation is simple: it transcodes YAML on standard input to JSON (using the key-order-preserving
equivalent of yaml.safe_load_all to avoid dangerous vulnerabilities in YAML/PyYAML design) and pipes it to jq:
cat input.yml | yq .foo.bar
Or specify the filename directly:
yq .foo.bar input.yml
By default, no transcoding of jq output is done. Specify the --yaml-output/-y option to transcode it back
into YAML (using the key-order-preserving equivalent of yaml.safe_dump_all):
cat input.yml | yq -y .foo.bar
Use the --width/-w argument to pass the line wrap width for string literals.
All other command line arguments are forwarded to jq. yq forwards the exit code jq produced,
unless there was an error in YAML parsing, in which case the exit code is 1. See the jq manual for more details on jq features and options.
Compatibility note
This package's release series available on PyPI begins with version 2.0.0. Versions of yq prior to 2.0.0 are
