$ yj --help
yj 1.2.0

Command line tool that converts YAML to JSON

USAGE:
    yj [FLAGS] [OPTIONS] [INPUT]

ARGS:
    <INPUT>    Input YAML file name. Defaults to stdin

FLAGS:
    -c, --compact    Use compact formatting for the JSON output
    -h, --help       Print help information
    -j, --json       Parse the input as JSON. For most use cases, this option
                     makes no difference. Valid JSON is valid YAML, so JSON
                     input will (should?) parse correctly even when being
                     handled with the YAML parser. Use this option when you
                     want failure (instead of weird results) when the input is
                     invalid JSON
    -V, --version    Print version information
    -y, --yaml       Format the output as YAML instead of JSON

OPTIONS:
    -o, --output <OUTPUT>    Output file name for the JSON. Defaults to stdout
