Our builds are using the macos: xcode: 10.2.1 image. The /bin/bash --version there is 3.2.57. Is there a way to upgrade the shell to bash 5 so I can use Bash’s built-in uppercase string conversion of
in my script? I have the same bash commands running fine on my Android side which is image circleci/android:api-28-node using Bash 5.0.3.
But on the iOS side, with xcode 10.2.1 image I get a “bad substitution” error.
