How to configure core are generated under specified directory in linux

In Linux we can configure the core dump location , so that we can assign a specific location on the linux os so that coredump(crash logs) are always written under specific directory in linux. To enable this follow below steps :

1. Open .bashrc file under /root.(if this file is not available under /root then you can create one too.)
2. Add the below lines to the file.

          sysctl -w kernel.core_uses_pid=1

          if [ ! -e /root/corefiles ]

          then

                 mkdir -p /root/corefiles

          fi

          echo /root/corefiles/core > /proc/sys/kernel/core_pattern

          ulimit -c unlimited

This will enable all the process core dump (crash logs) to be written under /root/corefiles directory always.
