bash to sh

[Liwei Ma (davidmlw)]

The docker image has no bash. Use sh instead.

Please target branches at master

In master we handle this by adding bash to the actions container

wit/actions/wit/Dockerfile

Line 4 in 9fdc590

RUN apk add bash --no-cache

By the way, this change also won't work correctly on all systems, since I used bash-specific syntax (the [[ ]]) which are not part of the POSIX standard. I know for a fact that dash installed as /bin/sh on Ubuntu-based systems will not support that syntax.

If you just use the wit action targeting the latest commit on master, you should get bash installed in the Docker container and it should work around this issue.

I see. Seems better way is to apk add bash
