gcore - Generate a core file of a running program
gcore [-o filename] pid
Generate a core dump of a running program with process ID pid. 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.
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
