The crs command is a Rust version of the Carbon CLI.

Carbon can make a HTTP request, then sort, filter and display the HTTP response headers.

NOTE: The name comes from carbon filtering: method of filtering impurities.

Usage

The default behaviour is to display all response headers, followed by the HTTP status code:

Usage

• The --filter flag will attempt a partial match for each comma-separated value.
• The --json flag outputs the data as JSON.

NOTE: The following example pipes to jq for pretty-printing.

Example of filtering Example of filtering and JSON

• The --body flag will display the response body below the HTTP headers/status.

NOTE: The --body flag is incompatible with the --json flag
i.e. don't use --json and also try to include the response body.
