Sanitizing name of branch

Hello there :slight_smile: am trying to sanitize a branch name from dashes and full-stops in the following way.

  - echo ${DRONE_BRANCH//([-.])/_}

However, Drone does not seem to apply the transformation. If I try running the same build with this instead:

echo ${DRONE_BRANCH//-/_}

Everything seems to be working properly. Additionally, is there a way to replace the detected characters with blank instead of underscore. This also seems to work locally on Terminal but not on Drone.

Do you have any ideas? Thank you!

For anybody interested, try using sed instead. Direct multi-character sanitization is not supported by the underlying infrastructure either Drone or Docker.
