nl-classid-lookup(8)

💖 nl-classid-lookup — the manual, but make it cute 💖

okay so bestie, welcome to nl-classid-lookup, section 8 of the System Manager's Manual (that's the sysadmin-y corner of the man pages, iykyk). she's a libnl tool, she's tiny, she's iconic, and she does exactly one job and does it flawlessly. periodt. ✨

🌸 NAME 🌸

nl-classid-lookup — look up classid definitions, bestie. that's it. that's the whole name section. 🎀

🦋 SYNOPSIS 🦋

nl-classid-lookup [-hv] [-r] [--raw] name

💅 DESCRIPTION 💅

okay so here's the tea: nl-classid-lookup goes digging through the classid database looking for a matching entry. it's the little tool you use to turn qdisc/class names into classid values… and also the other way around, because she's versatile like that. 💁♀️

basically: name in, classid out. or classid in, name out. a queen who can do both directions. 👑

✨ OPTIONS ✨

• -h, --help — prints the help text straight to your console and then dips. exit, stage left. 🫶
• -v, --version — prints the versioning info to the console and bounces. very "hi, this is who i am, bye". 💜
• -r, --reverse — does a reverse lookup. so instead of name → classid, you feed her a classid and she prints the name. iconic behaviour, no notes. 🔄
• --raw — prints the raw classid in hexadecimal format. no pretty printing, no glow-up, just the raw hex, unedited, no filter. 💀

🎀 USAGE 🎀

want to resolve the qdisc/class name "interactive"? say less:

# nl-classid-lookup interactive

want to go the other way and look up the name of classid 1:2? reverse girlie:

# nl-classid-lookup -r 1:2

🍓 FILES 🍓

• /etc/libnl/classid

that's where the database lives, bestie. that's her home. 🏠
