✨ NAME ✨

grub-probe — bestie, it probes device info for GRUB 💅

Like, it's the little detective in the System Administration Utilities squad, section 8 of your man pages, and it goes and finds out what's actually going on with your disks so GRUB doesn't have to guess 🦋

🌸 SYNOPSIS 🌸

grub-probe [OPTION...] [OPTION]... [PATH|DEVICE]

okay so you just hand it options and a path (or a device, if you said -d, we'll get there) and it hands you back the tea ☕

🎀 DESCRIPTION 🎀

So the whole vibe is: you give it a path — or a device, but only if you passed -d — and it goes and probes the device information for it. That's the job. That's the whole job. And it eats. 👑

Here's every flag, no skips, no cap:

  • -0 — separate items in output using ASCII NUL characters (yes literally the NUL byte, she's not like other girls)
  • -d, --device — the argument you gave is a system device, not a path. Lowkey important distinction bestie, don't mix them up 🙈
  • -m, --device-map=FILE — use FILE as the device map. Default is default=/boot/grub2/device.map so if you don't say anything she's using that one 💖
  • -t, --target=TARGET — print TARGET. Available targets are: abstraction, arc_hints, baremetal_hints, bios_hints, compatibility_hint, cryptodisk_uuid, device, disk, drive, efi_hints, fs, fs_label, fs_uuid, gpt_parttype, hints_string, ieee1275_hints, msdos_parttype, partmap, partuuid, zero_check. Default is default=fs — so if you're not picky, you get fs and she moves on 🌈
  • -v, --verbose — print verbose messages. And listen, pass it twice and you unlock debug printing 👀 (iconic behavior honestly)
  • -?, --help — give this help list. The classic. The moment. 🫶
  • --usage — give a short usage message (short queen, minimal effort, we respect it)
  • -V, --version — print program version. Yes, capital V, not lowercase. Noted. 📝
Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. fr fr, that's the rule — if the long version needs a value, the short one does too 🧚

💜 REPORTING BUGS 💜
