okay so bestie, this is ffs(9) from the Kernel API Manual, and it's giving tiny-but-iconic bit-finding energy ✨

🌸 NAME 🌸

ffs — find first bit set 💅

✨ SYNOPSIS ✨

ffs (x );

🎀 ARGUMENTS 🎀

  • x — the word to search 🔍

🦋 DESCRIPTION 🦋

okay so ffs is defined the same way as the libc and compiler builtin ffs routines, no cap. therefore it differs in spirit from ffz (man ffs) — yes bestie, that's literally what it says 👀
