LSDAHDI(8)

💅 NAME 💅

lsdahdi — bestie, this is the manual page for LSDAHDI(8), and it does exactly one iconic thing: it lists all your DAHDI channels, with their types and their spans. That's it. That's the whole job. And she does it gorgeously. ✨

So like, lowkey decoding the columns for you bestie, because the layout goes crazy:

• The first column is the type of the channel — which is the port, for an analog device. 🎧
• The second column is the signalling, if it's been set. ✨

That's literally it. Types and signalling. She said "I'll give you the tea and nothing else." 💀

🌸 FILES 🌸

lsdahdi is, and I quote, a somewhat glorified cat /proc/dahdi/* . 😭 Like yes she's cat-core at heart but she's also so much more, okay?

• Unlike that command, she sorts the spans with the proper order. No chaos. No mess. Just order. 👑 (the way that matters…)
• She also formats the output slightly differently. A little glow-up. A little ✨ pizazz ✨.

Fr fr, that's the whole page. Go forth and check your channels, bestie. 💖
