Default shell, and option to select a different shell

It would be very useful, in order to convert easily a “normal” command if a shell parameter was supported, to change the shell executing the command. See: https://docs.github.com/en/free-pro-team@latest/actions/reference/workflow-syntax-for-github-actions#using-a-specific-shell

Also, from what I understand, on windows runners, the shell used is cmd, since the only way I could find to set a comment was using rem. The one used by default from normal actions is bash, I think it would be great if the action default was the same.

Sorry, I just double checked, I was wrong, the default on windows is powershell, not bash.

Here is the simplest example I could imagine

    - name: Ok
      if: runner.os == 'Windows'
      run: Get-ComputerInfo

    - name: Not ok
      if: runner.os == 'Windows'
      uses: nick-invision/retry@v2
      with:
        timeout_minutes: 10
        retry_wait_seconds: 1
        max_attempts: 3
        command: Get-ComputerInfo

[nick-invision]

Thanks to the contribution of @isaacrlevin, an alternate shell can now be specified with this action. Example:

uses: nick-invision/retry@v2
with:
  timeout_minutes: 10
  max_attempts: 3
  # if shell omitted, defaults to powershell on windows, bash otherwise.  Supported shells are bash, python, pwsh, sh, cmd, and powershell
  shell: pwsh
  command: dir
