FSTACK(1)

💅 FSTACK(1) — bestie edition 💅

okay so fstack lives in the Frysk manual, section 1, and it is literally here to print you a stack back-trace. that's it. that's the whole job. slay.

✨ NAME ✨

fstack — print a stack back-trace 🫶

---

🌸 SYNOPSIS 🌸

fstack [options] {pid... | core-file [ core-executable ]... }

---

🦋 DESCRIPTION 🦋

so basically, fstack prints a stack back-trace of all threads of the process or core-file you hand it. all the threads. every single one. no crumbs left. 💖

🎀 Stack Print Options 🎀

• -number-of-frames count — limit the back-trace to count frames. the default is to cap it at 10 frames. if you want the whole entire thing, specify 0 or "all". periodt.
• -lite — does a light-weight stack backtrace with only minimal info. it's literally the same as -print -. lowkey the "just give me the vibes" option.
• -rich — the deluxe version ✨ a detailed stack back-trace that includes, where possible, inlined function calls, parameter names and values, and debug-names. equivalent to -print inline,params,debug-names. main character energy fr fr.
• -print print-option,... — tell fstack exactly how much detail to put in the back-trace. print-option can be any of these besties:
  • debug-names — use debug information, like DWARF, to figure out the name of functions 👑
  • paths — include the full path to source files and libraries 🗺️
  • inline — include in-line functions in the back-trace 🧚
  • locals — include local variables from each frame 🍓
  • params — include the function parameters 🌈

and if you wanna negate a print-option, just prefix it with -. yes, a little minus sign. it's giving "not that one, bestie".

⭐ Standard Frysk Options ⭐

• -exe — the full path of the executable to read. 📖
• -noexe — do not attempt to read the corresponding executable when loading a core file. like, don't even try. 🙈
• -sysroot directory — the system root directory under which all executables, libraries, and source are located. the home base. the HQ. 🏠
• -debug class=level... — set internal debug-tracing of the specified Java class to level. level can be NONE, INFO, WARNING, FINE, and FINEST. if the level is absent, FINE is assumed; if the class is absent, the global level is set. iykyk 💅
