NAME

       gcore - Generate core files for running processes

SYNOPSIS

       gcore [-a] [-o filename] pid[s]

DESCRIPTION

       gcore  generates  a core file for the process(es) specified by process IDs, pid[s]. By default, each core
       file is written to core.pid, in the current directory.

       -a     (Linux only) ignore /proc/PID/coredump_filter and  also  dump  memory  mappings  marked  with  the
              'VM_DONTDUMP' flag. See info node Core File Generation for longer explanation.

       -o filename
              write  core  file  to  filename  if  one PID, or filename.pid if multiple PIDs, instead of default
              core.pid
