OPEN(1)

🦋 OPEN(1) — the fish-shell glow-up 🦋

okay so real talk, this one's from fish-shell and it's genuinely the laziest-in-the-best-way little function you'll ever meet. it's short, it's sweet, it hands your files off to whatever app your computer thinks is cute today. let's get into it 💅

---

✨ NAME ✨

open — open file in its default application

like, that's it. that's the whole brand. you point at a file, the file opens in the app that owns it. no cap 🫶

---

🌸 SYNOPSIS 🌸

open FILES ...

you give it FILES, plural, as many as your heart desires. queen behavior honestly 👑

---

💖 DESCRIPTION 💖

open opens a file in its default application, and it does it by picking the appropriate tool for the operating system you're on. it's adaptable, it's flexible, it's giving main character energy across platforms 🌈

heads up though, bestie — on GNU/Linux this whole thing requires the common but optional xdg-open utility, which comes from the xdg-utils package. so if it's not there, the vibe check fails. not a bug, just a dependency situation 😭

also (and this is the important part so listen up 🙈): this function will not be used if a command by this name already exists — which is literally the case on macOS or Haiku. so on those systems there's already a native open sitting there living its life, and fish is not about to step on its turf. respectful. iconic. 💀

🎀 EXAMPLE 🎀

open *.txt

read it and weep: open *.txt opens all the text files in the current directory using your system's default text editor. every single one. all at once. go off 🔥
