Amendment to clarify shell behaviour with apptainer exec.

[jkwmoore]

Description of the Pull Request (PR):

A suggestion for clarification on how the shell will behave when using operators with apptainer exec. I accept this may not be necessary since people should be familiar with how the shell works but this might be helpful.

Thank you for being willing to contribute to the documentation, but I don't think that this is a good place for the information.

I think a better place would be at the end of the "Working with Files" section further down on that page, after where it talks about pipes and redirects working normally. Rather than making it a warning, it could just be in the regular text and say to not expect that complex command lines will all be passed to {command} since the shell will first apply its normal parsing rules. You could also give an example of quoting that shows how to pass a command line with && to {command}.

Come to think of it, that last piece in that section about pipes and redirects is more about the shell than about Files. I would add a new section header before that "Working with the Shell" when you add this new information.

Are you interested in updating this as I requested?

Unfortunately this one is a bit on my back-burner as this isn't part of my day job. I'll plan on contributing at when I have a bit of contiguous free time booked since I'll need to re-read around the page / fit it into the bulk.

I am thinking I can probably get to this at some point mid next week.
