NAME

       gcore - Generate a core file of a running program

SYNOPSIS

       gcore [-o filename] pid

DESCRIPTION

       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.

OPTIONS

       -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.

SEE ALSO

       The full documentation for GDB is maintained as a Texinfo manual.  If the "info" and "gdb" programs and GDB's Texinfo documentation are
       properly installed at your site, the command

	       info gdb

       should give you access to the complete manual.
