FCORE(1)

💖 NAME 💖

fcore — bestie, this one extracts a core file from a process. like, pulls the whole vibe of a running program out and saves it to disk ✨

---

✨ SYNOPSIS ✨

fcore [options] {pid...}

---

🦋 DESCRIPTION 🦋

okay so listen. fcore constructs a core-file from a running process, and writes it to disk. that's the whole gig. it's giving "freeze frame but make it forensics" 📸

💅 OPTIONS 💅

• -a, -allmaps — write all the readable segment maps. by default fcore tries to emulate the gcore segment writing strategy, but if you say this, she's writing every readable map, no cap 🗺️
• -s, -segments regex — only writes the segments that match the regex you gave. everything else? elided. gone. not invited to the party 🙈
• -o output-file — names the core file. default is core. and heads up, the core-file extension will still use the pid of the process being dumped, so the pid is coming along whether you like it or not 🎀

👑 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.
• -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. the 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. very "choose your own adventure" of her honestly ⭐
