FCATCH(1)

✨ FCATCH(1) ✨

okay bestie, so this is fcatch from the Frysk manual, section 1 💖 and honestly? it's giving crash detective. she prints a stack back-trace of a program as it crashes. that's the whole vibe.

🌸 NAME 🌸

fcatch — print a stack back-trace of a program as it crashes

---

🎀 SYNOPSIS 🎀

fcatch [options] {program arg ... }

---

🦋 DESCRIPTION 🦋

so like, fcatch generates stack backtraces from a running application as it crashes, or upon receiving a variety of signals. she's literally standing there with a camera going "smile, you're on film" while your program faceplants 💀

💅 Stack Print Options

• -number-of-frames count — limit the back-trace to count frames. the default is to limit the back-trace to 10 frames. specify 0 or "all" to print all frames. no cap, all frames, main character energy 👑
• -lite — perform a light-weight stack backtrace containing only minimal information. equivalent to -print -. lowkey bare minimum, and that's valid.
• -rich — perform 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. she's highkey doing the most and we love that for her ✨
• -print print-option,... — specify the level of detail to include in a stack back-trace. print-option can be any of:
  • debug-names: use debug information, such as DWARF, to determine the name of functions
  • paths: include the full path to source files and libraries
  • inline: include in-line function in back-trace
  • locals: to include local variables from each frame
  • params: include the function parameters

to negate a print-option prefix it with "-". yes babe, the minus sign is doing the "no thanks" hand gesture 🙈

🌈 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. she said "i'm not reading that" and honestly, fair.
• -sysroot directory — the system root directory under which all executables, libraries, and source are located.
• -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. it's giving ✨internal monologue, but for Java classes✨

⭐ EXAMPLE ⭐

fcatch 1234

fcatch /usr/bin/foo

like, either you point her at a pid or you point her at a whole program. both iconic 🫶
