FUNCTION::CMDLINE_AR(3stap)

💖 FUNCTION::CMDLINE_AR 💖

okay bestie, welcome to the Context Functions corner of the SystemTap tapset reference, aka 3stap, and today's main character is a lil function called cmdline_arg 💅

---

✨ NAME ✨

function::cmdline_arg — fetch a command line argument 🎀

---

🌸 SYNOPSIS 🌸

cmdline_arg:string(n:long)

---

🦋 ARGUMENTS 🦋

• n — the argument you wanna get. lowkey important: zero is the program itself 👑

---

💜 DESCRIPTION 💜

so basically it hands you back the requested argument from the current process. that's it, that's the whole vibe. ✨

and if there aren't that many arguments? or if something goes sideways while retrieving it? you just get the empty string back. no drama, no crash, just a quiet little "" 🙈

oh and heads up — argument zero is traditionally the command itself, which is giving very much "the program is the star of its own show" energy 💖

no cap, the "empty string" thing is your whole error path. if you were expecting a real argument and got nothing, that's the function telling you "girl, it's not there" 😭

and that's a wrap, bestie 🫶 this lil page came straight out of the SystemTap Tapset Reference, version dated September 2026 — go forth and slay those command line args 💅✨
