fcore - Man Page

extract a core file from a process

Synopsis

fcore [options] {pid...}

fcore constructs a core-file from a running process, and writes it to disk.

-a, -allmaps: Write all readable segment maps. The default level is to attempt to emulate gcore segment writing strategy. By specifying this option, fcore will write all readable maps.
-s, -segments regex: Writes only the segments that match the regex specified. Elide all other segments.
-o output-file: Specifies the name of the core file. Default is core. The core-file extension will still use the pid of the process being dumped.

-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 (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.
