Hi @Alexander Pettitt, great question! The pre-defined aliases, like :py, :sql, and :history, are built into the system I believe. Custom aliases, yes, they come from the ~/.iris_init file, which is user-specific and located in the user's home directory.

To make aliases instance-specific, the only workaround I’m aware of is to use separate system users for each IRIS instance, each with its own .iris_init file. Unfortunately, I don’t believe there’s a native way to directly tie aliases to a specific instance unless this user-level separation is implemented.

Let me know if you’ve explored other approaches!

Regards,
Ash
