NAME

       gcore - Generate a core file of a running program

SYNOPSIS

       gcore [-a] [-o prefix] pid1 [pid2...pidN]

DESCRIPTION

       Generate core dumps of one or more running programs with process IDs pid1, pid2, etc.  A
       core file produced by gcore is equivalent to one produced by the kernel when the process
       crashes (and when "ulimit -c" was used to set up an appropriate core dump limit).
       However, unlike after a crash, after gcore finishes its job the program remains running
       without any change.

OPTIONS

       -a  Dump all memory mappings.  The actual effect of this option depends on the Operating
           System.  On GNU/Linux, it will disable "use-coredump-filter" and enable
           "dump-excluded-mappings".

       -o prefix
           The optional argument prefix specifies the prefix to be used when composing the file
           names of the core dumps.  The file name is composed as prefix.pid, where pid is the
           process ID of the running program being analyzed by gcore.  If not specified, prefix
           defaults to gcore.

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.
