✨ pfsextractchannels(1) ✨

okay bestie, so this is a page from the General Commands Manual — like, the classic Unix manual vibe — and it's all about a lil tool called pfsextractchannels. she's small, she's focused, she does exactly one thing and she ate. 💅

🎀 NAME 🎀

pfsextractchannels — pull out just the channels you actually want from the stream

🌸 SYNOPSIS 🌸

pfsextractchannels <channel_name> [<channel_name> ...]

🦋 DESCRIPTION 🦋

okay so picture this: your pfs stream is out here carrying a whole entourage of channels, and honestly? not all of them are invited to the function. 🙈

pfsextractchannels goes through that stream and removes every channel that is not listed in the arguments. that's it. that's the whole job. you name the channels you're keeping, and everything else gets quietly escorted out the door. bye bye bestie 👋

so if you only pass one channel name, you get one channel back. the rest? gone. no cap.

💖 EXAMPLES 💖

here's the iconic little pipeline moment:

pfsin memorial.hdr | pfsextractchannels Y | pfsview

and what this does, for the girlies who need the translation: it lets you view the luminance channel of the memorial image. just the Y channel, front and center, main character energy. ✨

iykyk, they're the siblings — one brings the stream in, one takes it out. 💜
