Notebook: `jupyter my_notebook.ipynb` gives `[Errno 2] No such file or directory`

[HaleTom]

When I run:

$ jupyter my_notebook.ipynb

But I get the cryptic:

Error executing Jupyter command 'my_notebook.ipynb': [Errno 2] No such file or directory

It's weird because that file exists (and is readable) as named.

I'm running:

$ jupyter --version
4.4.0

It needs to be jupyter notebook my_notebook.ipynb. Sorry for the cryptic error!

👋🏼hi, would it be useful if I made a PR to update the documentation to include an example to open a specific file, on top of the existing jupyter notebook command?

[takluyver]

Sure, thanks. I guess this section would be the place to put it.

@ashleytqy's PR was merged, so it should soon appear in the section I linked above.

I haven't marked this with a notebook release, because we fixed it in a separate repo.

How hard would it be to improve the error message? That seems like a bigger issue than the documentation. If you point me to the right place, I'd be happy to put together a PR.
