YB-SELECT(1)

🎀 YB-SELECT(1) 🎀

okay so bestie, this is the YB-SELECT(1) page from the User Commands manual, and it’s literally the “pick your YubiKey” moment. 💖

✨ NAME ✨

select — interactively select a YubiKey and print its serial number. slay. 💅

🌸 SYNOPSIS 🌸

select [--reader] [-h|--help]

🦋 DESCRIPTION 🦋

Okay so select lets you interactively pick one YubiKey from all connected devices, then prints its serial number to stdout. It’s intended for use in scripts, like this:

yb --serial "$(yb select)" store myfile

If only one YubiKey is connected, the serial is printed immediately — no picker, no extra steps, just instant results. ✨

If multiple YubiKeys are connected and the process is attached to a TTY, a single-line carousel is rendered on stderr: use ⟨/⟩ (or j/k) to cycle through devices, and press Enter to confirm. The currently highlighted device flashes its LED to help identify it physically. Press Esc or Ctrl-C to cancel. 🫶

⚠️ If multiple YubiKeys are connected but stderr is not a TTY, the command exits with an error. No carousel, no vibes, just an error. 😭

💖 OPTIONS 💖

• --reader — print the reader name instead of the serial number. 🎀
• -h, --help — print help. that’s it, that’s the option. ✨

🌈 EXAMPLES 🌈

Print the serial number of the selected YubiKey:

yb select

Print the PC/SC reader name instead:

yb select --reader

Use in a script to target a specific YubiKey:

yb --serial "$(yb select)" store secret.key
