Are there Julia commands or environment settings that I can put at the top of a notebook (.ipynb) file, or put in .juliarc.jl, to get the same effect as launching julia from the command line with various option switches?

For example, I would sometimes like to do

```
 $ julia -O3

```

or

```
$ julia -g

```

or

```
$ julia -p 1

```

etc., but run in the jupyter-notebook environment rather than in a terminal.

Sorry if this has already been answered. I **did** search this forum, the docs, and Google, but haven’t found an answer yet. (I cross-posted this question as an issue on the jupyter/help github page.)

This surely isn’t the answer that you’re looking for, but I thought I’d mention that using [Literate.jl](https://github.com/fredrikekre/Literate.jl) together with [Revise.jl](https://github.com/timholy/Revise.jl) is a great alternative to Jupyter notebooks (and it would be obvious how to do what you’re asking, because you could just do exactly what you already said).
