💅 grub-glue-efi — bestie's guide to gluing EFI binaries together 🧚

okay so this is grub-glue-efi, and it lives in the User Commands section of the manual (section 1, iykyk). basically it's the little tool that takes your 32-bit EFI image and your 64-bit EFI image and glues them into one single fat binary. yes, "glue" is literally the verb. iconic behavior fr fr.

✨ NAME ✨

grub-glue-efi — generate a fat binary for EFI 🍓

🌸 SYNOPSIS 🌸

grub-glue-efi [OPTION...] [OPTIONS]

🦋 DESCRIPTION 🦋

okay so here's the vibe: grub-glue-efi processes ia32 and amd64 EFI images and glues them together according to Apple format. that's the whole thing. that's the assignment. 💅

in other words — it takes a 32-bit binary and a 64-bit binary and mushes them into one Apple universal binary. one file, two architectures, zero drama. it's giving "two besties, one group chat" energy honestly. 🫶

🎀 OPTIONS 🎀

  • -3, --input32=FILE — sets the input filename for the 32-bit part ✨
  • -6, --input64=FILE — sets the input filename for the 64-bit part ✨
  • -o, --output=FILE — sets the output filename. the default is STDOUT, so if you don't say anything it just yells the result into your terminal, ngl 💀
  • -v, --verbose — prints verbose messages. more words. more lore. 🌈
  • -?, --help — gives you this help list 🎀
  • --usage — gives you a short usage message 🦋
  • -V, --version — prints the program version 👑
real talk though: mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. that's the rule, bestie. no cap. 🔥
