GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Exposing your clipboard over SSH

I frequently administer remote servers over SSH, and need to copy data to my clipboard. If the text I want to copy all fits on one screen, then I simply select it with my mouse and press CMD-C, which asks relies on m y terminal emulator (xterm2) to throw it to the clipboard.

This isn't practical for larger texts, like when I want to copy the whole contents of a file.

If I had been editing large-file.txt locally, I could easily copy its contents by using the pbcopy command:
