Unfortunately, while trying to delete previous core dumps, I set my core file size

  • 0

Unfortunately, while trying to delete previous core dumps, I set my core file size hard limit to 0. Is there a way to change the hard limit of a ulimit parameter?

host-101-178:Labs evan$ ulimit -c 0
host-101-178:Labs evan$ ulimit -c 1000000
-bash: ulimit: core file size: cannot modify limit: Operation not permitted
host-101-178:Labs evan$ ulimit -c unlimited
-bash: ulimit: core file size: cannot modify limit: Operation not permitted

    Log out and log back in and the hard coredumpsize limit will be back to the default. Use

    ulimit -S -c

    to change the soft limit.
