Core Plugins and tasks Reverse

Core Plugins and tasks Reverse
Certified
Reverse a file (last line first) in Kestra internal storage.

Copies the source file locally, writes lines in reverse order with a configurable separator, and uploads the result. Charset defaults to UTF-8.

Handy for log-like files where newest-first order is desired.

yaml
type: io.kestra.plugin.core.storage.Reverse

Examples

        commands:
          - echo "1
2
3" > numbers.txt
        outputFiles:
          - "numbers.txt"

      - id: reverse

        from: "{{ outputs.generate_file.outputFiles['numbers.txt'] }}"
