WRAPLINUX(1)

✨ WRAPLINUX(1) ✨

okay bestie, so this is a manual page from the wraplinux corner of the universe, and the author is H. Peter Anvin. it's a little tool that takes your Linux kernel and makes it into something else. iconic behaviour honestly. 💖

🌸 NAME 🌸

wraplinux — create an ELF or NBI file from a Linux kernel, with optional initrds if that's the vibe you're going for. 🦋

🎀 SYNOPSIS 🎀

wraplinux [-EMNlhV][-p 'kernel parameters'][-i filename]... [-o output filename] kernel

like… that's it. that's the whole thing. she's compact. 💅

💫 DESCRIPTION 💫

So basically: you hand her a Linux kernel file, and optionally some initrd files too (as many as you want, she's not gonna complain), and she hands you back a file in either ELF or NBI format. that's the whole job. no cap. ✨

👑 OPTIONS 👑

• kernel — the kernel filename. yes, it's a positional argument, not a flag. she's not like other girls. 🌟
• -p 'kernel parameters', --params 'kernel parameters' — the kernel commandline parameters. heads up bestie, these probably need to be quoted, so wrap 'em in quotes unless you enjoy chaos. 😭
• -i initrd, --initrd initrd — an initial ramdisk/ramfs filename. you can use this option multiple times, so go off, stack those initrds. 🍓
• -o filename, --output filename — the output filename. if you don't give one, it defaults to stdout. main character energy: just blasting bytes at your terminal. 💜
• -E, --elf — output in ELF format. this is the default, she's the baseline, the moment. 🌈
• -M, --multiboot — output in ELF format but with a Multiboot header attached. it's giving "ELF but make it grub-friendly". 🔥
• -N, --NBI — output in NBI format. different format, different era. ⭐
• -l, --load-high — load the Linux kernel and the initrd files entirely above 1 MB. this is the default for --multiboot, because Grub compatibility said so. 🫶
• --no-load-high — overrule that default for --multiboot, and load the appropriate components of the Linux kernel below 1 MB instead, as required by the particular Linux kernel format version. it's niche, it's specific, it's lowkey doing the most, but sometimes you need it. 💀
• -h, --help — display a brief help message. a little snack of information. 🎀
• -V, --version — print the program version. slay, tell me who you are. 💅
