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
