I might be weird, but for me the most obvious way to transfer a small directory is to do

    tar -cz dir | base64

Copy output into clipboard

    base64 -d | tar -xz

Paste from clipboard into input

Works flawlessly to move configs and stuff between servers.

I actually love the blend between terminal and GUI. For this example I'm using CLI tools to produce text and I'm using GUI to scroll, select and copy&paste the text between two terminal tabs. I wish developers put more emphasis on empowering terminal with GUI capabilities.

Under certain circumstances, like where machines are not directly accessible to each other and you’re only able to connect by Remote Desktop or something, that’s not actually bad way to do that. But for machines that are on the same network, using a weird invocation of tar and nc instead of just using, say, rsync is an odd choice. And for machines connected to each other over the Internet, it’s positively insane.

On Mac you can use pbcopy to copy something your pasteboard aka clipboard.

So the first command becomes:

   tar -cz dir | base64 | pbcopy

And of course you can use pbpaste for the inverse. Doesn’t work over SSH though, which is almost certainly how you’d be using this.

True that unless ssh tunnels the pasteboard nowadays ;)

GP was doing this using GUI and TUI so it's a case of having two terminals open to two different machines I assume.

Yeah, but that’s exactly the case where it won’t work. pbcopy and pbpaste run locally, so if you’re connected to a remote Mac they won’t work properly (they will just cut/paste to the remote machine’s local pasteboard), and if you’re connected to a non-Mac the commands won’t exist at all. The only case where they would work is, say, connecting from one Mac to another via something like VNC that does do pasteboard sharing, and you’re trying to copy a file structure from a remote system to a local one. If you’ve got two terminal windows open to two different machines, you’ll have to cut and paste manually.
