NAMEgcore - Generate a core file of a running program
SYNOPSISgcore [-o filename] pid
DESCRIPTIONGenerate a core dump of a running program with process
IDpid. Produced file is equivalent to a kernel produced core file as if the process crashed (and if "ulimit -c" were used to set up an appropriate core dump limit). Unlike after a crash, after gcore the program remains running without any change.
- -o filename
The optional argument
filename specifies the file name where to put the core dump.
If not specified, the file name defaults to core.pid,
where pid is the running program process ID.

GDB's Texinfo documentation are properly installed at your site, the command
