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  explana‐
              tion.

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