jq Command
The jq command filters and processes JSON input.
This command uses the well-known jq JSON processor to manipulate incoming JSON. Please refer to the jq manual for details.
Usage
jq [--no-rewrite] <filter>
Parameters
| Parameter | Description | Required? | Default Value |
|---|---|---|---|
filter | jq filter | ✔️ |
Options
| Option | Description | Required? |
|---|---|---|
--no-rewrite | Do not preprocess the jq filter, but send it as-is | ❌ |
By default, a jq filter expression is rewritten to match the currently defined section (see Property Path). A filter expression like .foo.bar will be rewritten to .reported.foo.bar. In order to access a property via an absolute path like /metadata.protected, you would need to write ./metadata.protected.
It is possible to use the --no-rewrite option to turn off this rewriting. Fix Inventory will not rewrite the filter expression, sou you would need to pass: {bar: .reported.foo.bar, protected: .metadata.protected}.
