LPF(8)

💅 LPF(8) — bestie edition 🎀

okay so welcome to the lpf page, section 8 of the manual, and honestly? this one's a lil vintage gem ✨

🌸 NAME 🌸

lpf — the lpd filter for nroff output 🫶

🦋 SYNOPSIS 🦋

lpf -w width -l length

like, that's the whole thing. two flags. she's low maintenance 💅

🌈 DESCRIPTION 🌈

so lpf is a filter — meaning it sits in a pipeline and vibes 🧚 — and what it does is read the output of nroff and then convert any lines that have ^H's in them into overwritten lines. yes bestie, that's a real thing, that's the whole job, she's doing it 💖

the way that this works is basically like ul(1), except lpf is so much better, no cap 👑

• it can handle more than 2 overwrites (iconic)
• and it is written with some style ✨ periodt

📝 NOTES 📝

real talk for a sec: this program was designed long ago, and it is not much if any use today. she's giving legacy. she's giving museum piece. we still love her tho 🥺

💀 BUGS 💀

ngl this one is a little unhinged: lpf will send itself the STOP signal when it encounters the character sequence \031\1. not a drill, not a typo — it stops itself. self-care I guess?? 😭

👑 a lil sign-off 👑

this page comes from the Debian User's Guide sources, and it was dated 25 February 1999 — shoutout BSD for the original 🌈💜 stay safe out there, and remember: if your filter starts sending itself signals, that's between her and the kernel 🫶✨

💖 mwah, go read your nroff output responsibly 💖
