NAME         top

       gcore - Generate a core file of a running program

SYNOPSIS         top

       gcore [-o filename] pid

DESCRIPTION         top

       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         top

       -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.

       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.
