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…

Never had heard of this before. Some other cool tools in the "additional tools for X-Code" package which I had also never heard of. https://developer.apple.com/download/all/

Thanks for sharing.

When mentioning `open` they should have noted that `open ` will open the given file with its associated app. It’s indispensable.

Especially

    open .
if you need to drag a file somewhere. One thing that kind of breaks my muscle memory here is the opposite, something like

    firefox file.html
doesn't work and you have to fiddle with the arguments to get open to launch a non-default application.

`pbcopy` and `pbpaste` are one of my most-loved in the list. Dealing with some minified json, switching to iTerm, doing `pbpaste | json_pp | pbcopy` and having a clean output is _so_ nice.

I like to use `pbcopy` when exporting public keys to external services like GitHub.

`cat ~/.ssh/mykey.pub | pbcopy`

Self-plug of displayplacer[0] for changing screen resolutions/rotations/etc via the command line. [0] https://github.com/jakehilborn/displayplacer

Does this tool also allow me to change my iPad screen on Sidecar from landscape/horizontal into vertical?

Earlier quoted context omitted.

If I had a nickel for each `cat foo.json | jq | pbcopy`, I'd be a rich man :)

That's a useless use of cat. You can use `jq . foo.json | pbcopy` or `jq < foo.json | pbcopy`.

Speaking for myself, the first form is more natural- even if it’s a useless cat, because I’m always cat-ing files to see their structure. Then progressively tacking on different transforms. And then finally putting it in whatever I want as output.

It’s so ingrained, I’m more likely than not to just write it out that way even when I know exactly what I’m doing from the onset.

It's not something that I've tried. There was a user report at the bottom of this GitHub issue that states sidecar rotation does not work.

`tmutil` could be added to this list, it's a management cli for Time Machine

I don't even use Time Machine for my off-machine backups, but I use tmutil to create local snapshots so I can easily back out of changes by using the Time Machine GUI to restore files from the snapshot.

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`
