💅 GPIODETECT(1) — the gpiodetect girlies' guide

okay so bestie, welcome to gpiodetect, part of the libgpiod command-line utility fam. yes this is manual page section 1 and yes it's about to be your new fave thing. sit down, hydrate, let's go 🫶

✨ SYNOPSIS ✨

gpiodetect [OPTIONS] [chip]...

that's it. that's the whole vibe. some options, some chips, slay 💅

🦋 DESCRIPTION 🦋

so what does it do? it lists GPIO chips, prints their labels and the number of GPIO lines each one has. that's the whole job and it does it gorgeously. no cap ✨

now here's the part where you need to pay attention, bestie, because this is giving main character energy:

chips can be identified by number, name, or path. like, all three of these refer to the exact same chip:

  • 0
  • gpiochip0
  • /dev/gpiochip0

fr fr, same chip, three outfits. it's giving versatile icon 👑

and if you don't specify any chips at all? then all of them get listed. every single one. the whole friend group shows up to the party 🎀

🔥 OPTIONS 🔥

  • -h, --help — display this help and exit. the "hey what does this do again" button, iconic for when you forgot everything 🫶
  • -v, --version — output version information and exit. the "who am i, really" button, tells you what version you're running ✨
