Examples:

  1. Replaces the README.rst file on the package bob/bob.extension, through a merge-request, using the contents of the local file with the same name:

     $ bdt commitfile -vv bob/bob.extension README.rst


  2. Replaces the README.rst file on the package beat/beat.core, specifying a commit/merge-request message:

\b
     $ bdt commitfile -vv --message="[readme] Update [ci skip]" beat/beat.core README.rst


  3. Replaces the file conda/meta.yaml on the package bob/bob.blitz through a merge request, specifying a commit/merge-request message, using the contents of the local file new.yaml, set merge-when-pipeline-succeeds, and the name of the branch to be creatd:

\b
     $ bdt commitfile -vv bob/bob.blitz --path=conda/meta.yaml --branch=conda-changes --auto-merge new.yaml
