 ## Honourable mentions
 
-- `mdfind`: Spotlight search, but in the terminal. I generally use Spotlight itself (or rather the excellent [Raycast](https://www.raycast.com/)).
-- `say`: This command makes your Mac speak the text you give it.
-- `screencapture`: This command allows you to take screenshots and save them to a file. I prefer using `cmd-shift-5` for this.
-- `networksetup`: This command allows you to configure your network settings programmatically. I found its API very intimidating, and so I haven't really used it much.
