Act version

act version 0.2.20

Expected behaviour

When providing a bash script in the run section of steps for a job, we expect the shell to be executed with the same options as GitHub Actions.

Actual behaviour

act runs with bash --noprofile --norc -eo pipefail {0}

GitHub Actions runs with /bin/bash -e {0}

The difference of pipefail is producing different behaviour when running our shell script with act locally.

Workflow and/or repository

Failing if the grep on line 41 fails:
