💖 NAME 💖

fbtest — test if a virtual console is mapped to a frame buffer devive 💅 (yep, devive is literally the spelling in the original NAME line — lore preserved, iykyk).

✨ SYNOPSIS ✨

fbtest [-f <fb_device>] [-C <vc_device>]
fbtest --help

that's the shape of it. the --help line is in the synopsis too, periodt. 💅

🌸 DESCRIPTION 🌸

The program fbtest(8) is used to test if a virtual console, e.g. /dev/tty1 is mapped on a frame buffer device. that's the whole mission, bestie. lowkey simple, highkey useful. ✨

💅 OPTIONS 💅

• -f, --fb=<fb_device> — this one says "bestie, use another frame buffer device than the default /dev/fb0." you're picking the fb device, not the vibe.
• -C, --vc=<vc_device> — this one says "bestie, use another virtual console than the default /dev/tty1." yes, capital C, don't lowercase it, she's iconic like that.

🦋 EXIT STATUS 🦋

• 0 — the virtual console is mapped onto a frame buffer device. slay, it's giving success. ✨
• 1 — the virtual console is not mapped onto a frame buffer device. not slay, but at least you know. 😭

🍓 FILES 🍓

• /dev/fb0
• /dev/tty<1...63>

these are the paths in the mix, exactly as listed. 🫶
