UEFIVARS(1)

📦 version 1.2, in ubuntu resolute, ubuntu stonking

💖 UEFIVARS 💖

okay so bestie, welcome to uefivars — she's a little helper tool for analyzing, converting and modifying UEFI variable stores. yes it's giving bootloader-adjacent chaos but don't worry, we're gonna get through this together 🫶

This is the User Commands girlie from the uefivars manual, and she ate. periodt.

✨ DESCRIPTION ✨

So here's the vibe — this is how you call her:

uefivars [-h] -i INPUT -o OUTPUT [-I INPUTFILE] [-O OUTPUTFILE] [-P PK]
[-K KEK] [-b DB] [-x DBX]

Like, <pink>-i and <pink>-o are the non-negotiables, everything else is optional slay 💅

🎀 options: 🎀

  • -h, --help — shows this help message and then dips. exit stage left. that's it, that's the whole job 💖
  • -i INPUT, --input INPUT — the input type bestie. pick one: "aws", "json", "edk2", "efivarfs", "none" 🌸
  • -o OUTPUT, --output OUTPUT — the output type. your options are "aws", "json", "edk2[,filesize=512]" — yes that filesize=512 is part of the edk2 option, don't come for me, that's just how she is ✨
  • -I INPUTFILE, --inputfile INPUTFILE — the input file. and if you don't give her one? she reads from stdin, no big deal 💜
  • -O OUTPUTFILE, --outputfile OUTPUTFILE — the output file. skip it and she writes to stdout instead, easy 🦋
  • -P PK, --PK PK — inserts PK from the file you give her. usually that's PK.esl 👑
  • -K KEK, --KEK KEK — inserts KEK from the given file, which is usually KEK.esl 🔥
  • -b DB, --db DB — inserts db from the file, and yeah you guessed it, usually db.esl ⭐
  • -x DBX, --dbx DBX — inserts dbx from the file, typically dbx.esl. the whole key hierarchy is here and she's iconic for it 🌈
not me listing the entire secure boot key chain like it's a fit check. PK, KEK, db, dbx — the four horsemen, no cap 😭
