Why

azcopy exposes many transfer options, but Nextflow only surfaces blockSize and blobTier. Anything else (e.g. --put-md5, --log-level, --cap-mbps) is unreachable from a pipeline config.

What

  • Add azure.azcopy.opts config option, a string of extra command line options
  • Export the value as AZCOPY_OPTS in the Azure bash helper prelude and append it to the azcopy cp upload and download commands
  • Update docs and existing rendered-script test expectations
  • Add tests for the new option and for the flags reaching the copy commands

The value is passed through unquoted at the call site so multiple flags word-split as expected. No validation is applied; invalid options fail at azcopy.

Allow arbitrary command line options to be appended to the azcopy
upload and download commands, exposing azcopy features that are not
covered by dedicated config options.
