I’m trying to use a custom shell command to set an rc file for bash. What I want to do is:

shell: bash --rcfile ${{ github.workspace }}/.github/workflows/bashrc -eo pipefail {0}

or use a short form like this:

env:
SHELL: bash --rcfile ${{ github.workspace }}/.github/workflows/bashrc -eo pipefail {0}
...
# sometime later
- name: foo
shell: ${{ env.SHELL }}

In both cases it appears the context cannot be resolved within the shell parameter, as I get this error:

• Your workflow file was invalid: The pipeline is not valid. .github/workflows/ci.yaml (Line: 23, Col: 14): Unrecognized named-value: ‘env’. Located at position 1 within expression: env.SHELL,.github/workflows/ci.yaml (Line: 40, Col: 14): Unrecognized named-value: ‘env’. Located at position 1 within expression: env.SHELL

I get a similar error for the github context when I try the other method as well.

BTW, it would be handy to have the shell: option at the job level so we can set a default instead of just per-step.
