💖 PEMMICAN-CLI(1) — the pemmican girlie's guide 💖

okay bestie, sit down, we're learning pemmican-cli — it's the little command that checks boot-time PMIC issues and it's honestly doing the most for your Pi. 🌸

✨ NAME ✨

pemmican-cli — check boot-time PMIC issues. yep that's it, that's the whole job, and it does it flawlessly. 👑

🦋 SYNOPSIS 🦋

usage: pemmican-cli [-h] [--version]

like… it's two flags. two. it's giving minimalist icon behaviour. 💅

🎀 OPTIONS 🎀

  • -h, --help — shows the help message and then exits. your little "wait what does this do again" button. 🫶
  • --version — shows the program's version number and then exits. slay, it knows who it is. ✨

🌈 USAGE 🌈

so here's the tea: pemmican-cli is meant to be a one-shot operation, meaning it runs once and dips — it's typically launched by update-motd(5) at https://manpages.ubuntu.com/manpages/noble/en/man5/update-motd.5.html. very "I'm on the motd, I said what I said". 🎀

First thing it does: it checks whether the last reset occurred due to a brownout (that's an undervolt condition, bestie, aka your Pi got starved of juice 😭) and, if it was, it prints a warning to stdout.

If you wanna suppress this warning just for your user, just touch the file ~/.config/pemmican/brownout.inhibit. If you wanna suppress it system-wide, touch the file /etc/xdg/pemmican/brownout.inhibit.

⚠️ Warning: It is strongly recommended that any such notice is heeded, because brownout is very likely to lead to any manner of other (hard to predict or replicate) issues — up to and including data corruption. 💀 Put simply: suppressing this warning is probably a very bad idea!

If the last reset was normal (or there was no last reset at all), the script keeps going and further checks whether the power supply negotiated a full 5A feed. If it did not, that also results in a warning printed to stdout. no cap. 🔥

Now, the Pi 5 can be reliably operated without a 5A feed, provided the peripherals attached to it are relatively light in their power draw. So depending on circumstance, you may well wish to suppress this warning — which you can do for your individual user by touching the file ~/.config/pemmican/max_current.inhibit, or system-wide by touching /etc/xdg/pemmican/max_current.inhibit. 🌸
