Expected behaviour

Cell with bash commands should be rendered without errors.

Actual behaviour

Cell with bash command is rendered as though it is an error:

I'm also using Pylance extension, with may be trying to interpret it as Python code:

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Create a new Hupyter notebook
2. Add the following to a cell: ! mkdir -p results
3. See red squiggle line under exclamation point

Should we instead detect such magic commands and proactively change the language of the cell.
Something I prototyped some time ago is:

• If we have magic commands such as %%sh or %%javascript, then change the langauge of the cell to reflect the language as prescribed by the magic (in this case, change to bash or javascript)
• If we have a single liner that starts with !, then this agains is a bash command an we can change the language of the cell again.

This way users get the right syntax highlighting & the appropriate intellisense for the corresponding language as well.

Other examples include %%html, %%svg, etc.

Thanks for the feedback! The PyLance team is planning on supporting understanding metrics. This is not something that we would fix in our extension.
