While you're at it, `brew install coreutils`. The coreutils that ship with macOS lack a lot of features available on Linux. If you use bash, I recommend upgrading it, too, since Apple ships a 16 year old build (iirc due to legal issues associated with GPLv3) `brew install bash`
They're shipping zsh now.

I like to use `pbcopy` when exporting public keys to external services like GitHub. `cat ~/.ssh/mykey.pub | pbcopy`
I love this tool too! except one time I quickly typed `cat ~/.ssh/mykey | pbcopy` And sent it straight away to my coworker on Slack. I then spent the rest of the day making a new private key and adding my new pubkey to all of the 1000+ servers I had root access to. I mean we had tools to help but it still wasn’t fun. With great power/convenience comes the potential to do dumb things at lightning speeds!
Not a command-line tool but the network link conditioner is also really great. Never seen such a tool on another OS You can simulate a really bad network. Latency, bandwidth, packet loss etc. Great for testing but also if people insist on cameras being on. Just screw up the connection so bad that everyone gets annoyed with your blocky image and robot voice and suggest you turn off video and then you make it 'magicall…

The expanse of GNU coreutils features is questionable too: some are nice, some you can do without easily and rarely to never miss, and some are downright annoying (yes I'm looking at you, ls with colors+quotes)
Not a bad list of basic macOS specific cli tools. For a more in depth list, I usually reference https://ss64.com/osx/ .
Is there any easy shortcut to resizing an image by percentage or fitting to a specific size? Many a times, a website says "file needs to be no bigger than 2 MB", and I need to scramble with Preview app to resize teh app until it falls below that limit. A cli tool for that action would be very handy.
