    jq -r

    Published Feb 26, 2025 [  Shell  ]

    jq -r is a command-line option for the jq tool, which is used for processing JSON data. The -r (or --raw-output) flag tells jq to output strings as raw text rather than JSON-encoded strings.

    Example Usage:

    1. Without -r (default behavior):

    echo '{"name": "Alice"}' | jq '.name'
    

    Output:

    "Alice"
    

    (Quotes remain because the output is still JSON-encoded) 2. With -r:

    echo ‘{“name”: “Alice”}’ jq -r ‘.name’

    Output:

    Alice

    (No quotes, just raw text) When to Use -r

    When you need plain text output (e.g., when storing results in a variable or passing them to another command).
    When working with JSON data that includes URLs, filenames, or command outputs that should not be wrapped in quotes.
