+Which which is which?

+I had a bit of a "Tyrel you know nothing" moment today with some commandline tooling. 
+
+I have been an avid user of ZSH for a decade now, but recently I tried to swap to fish shell.
+Along the years, I've maintained a lot of different iterations of `dotfiles <https://gitea.tyrel.dev/tyrel/dotfiles>`_, and shell aliases/functions.
+I was talking to a friend about updating from ``exa`` to ``eza`` and then noticed I didn't have my aliases loaded, so I was still using ``ls`` directly, as I have ``alias ls="exa -lhFgxUm --git --time-style long-iso --group-directories-first"`` in my ``.shell_aliases`` file.
+
+I did this by showing the following picture: 
+
+.. figure:: {static}/images/2023/09/26_which.png
+   :alt: Screnshot of shell text saying "Which LS" and then the line under it saying "/usr/bin/ls"
+
+Because I expected it to show me which alias was being pointed to by ``ls``.
+
+My friend pointed out that "Which doesn't show aliases, it only points to files" to which I replied along the lines of "What? No way, I've used ``which`` to show me aliases and functions loads of times."
+
+And promptly sent a screenshot of my system NOT showing that for other aliases I have set up. Things then got conversational and be being confused, to the point of me questioning if "Had I ever successfully done that? Maybe my macbook is set up differrently" and went and grabbed that.
+
+Friend then looked at the man page for which, and noticed that there's the ``--read-alias`` and ``--read-functions`` flags on ``which``, and I didn't have those set.
+I then swapped over to bash "Maybe it's a bash thing only? I'm using Fish".
+
+Nope, still nothing! Then went to google, and it turns out that ZSH is what has this setup by default.
+Thank you `"Althorion" <https://stackoverflow.com/a/14196212>`_ from Stackoverflow for settling my "Yes you've done this before" confusion.
+
+It turns out that ZSH's ``which`` is equivalent to the ZSH shell built-in ``whence -c`` which shows aliases and functions.
+
+After running ``/usr/bin/zsh`` and sourcing my aliases (I don't have a zshrc file anymore, I need to set that back up), I was able to settle my fears and prove to myself that I wasn't making things up. There is a which which shows you which aliases you have set up, which is default for ZSH.
