TSORT(1)

✨ TSORT — okay bestie, let's get you in ORDER ✨

tsort — perform topological sort. that's it, that's the whole name, and honestly? it ate. 💅

---

🌸 SYNOPSIS 🌸

tsort [OPTION] [FILE]

like. one file. one dream. 🦋

---

💖 DESCRIPTION 💖

So here's the vibe: you hand tsort a bunch of pairs that say "this thing comes before that thing," and it hands you back a totally ordered list that's consistent with the partial ordering in FILE. It's giving "I sorted out the group chat drama and now everyone knows who's standing where." 👑

If you give it no FILE at all, or you pass - as the FILE, it reads from standard input. Bestie loves a good pipe. 🫶

Then there's the little diva flags, and yes they go right here in the description, don't @ me:

• --help — shows you this help text and then dips. that's the whole job. ✨
• --version — spits out the version info and exits. short, sweet, iconic. 🎀
