A desperate attempt to ssh-add all my SSH keys to SSH agent on MacOS using passphrases saved in 1Password.
If you happen to be using 1Password Cloud (subscription) then go here: https://github.com/lukaskuzmiak/SSHKeysVia1PasswordCloud
Put ssh-add-pass.sh and ssh-add-pass-helper.sh into your $HOME directory.
Adjust last lines of SSHKeysVia1Password.applescript to fit your SSH keys paths and 1Password item names.
Run as:
osascript /path/to/SSHKeysVia1Password.applescript
