You need to enable magic-space: https://relentlesscoding.com/posts/bash-magic-space/ # this will automatically expand any variables and history when you hit the spacebar after them, so you can eyeball before running.

Someone tell me what the zsh equivalent is?

In zsh you just type !1234<tab> and it expands to the full command so you can review and edit :D
