@stefano 'nix (Unix like derivative) shells are pretty neutral to any specific OS or distro. Would it be considered to add a category specifically for shell related topics? Or maybe a 'nix (*nix, nix) category for topics that are generic and apply to all Unix derivatives.

I like the second of the ideas. Thanks.

… I'll consider if add a generic Unix or a Shell category. Thanks!

For what it's worth, I have a subcollection in Zotero:

• Unix and the like

It suited me at the time, but it wouldn't be a good name for a category in Billboard. Maybe name the category:

• UNIX-like

– omission of the is intentional and then if anyone does write about UNIX itself, the category should be a good enough fit.

Pictured below: my current subcollections in Zotero. This is not a recommendation, it's a caution. In retrospect, I should have much greater use of tags (not pictured) instead of collections. It's a mess of my own making …
