Date: 2009jan24 Updated: 2020jun3 OS: Linux Product: bash Q. Linux: How do I enable/disable core dumps? A. Core dumps are every useful for debugging crashes but they can create clutter also. Enable this way:

ulimit -c unlimited

Disable this way:

ulimit -c 0

You can put either of these commands in your ~/.bashrc file if you wish. Also, check /proc/sys/kernel/core_pattern

cat /proc/sys/kernel/core_pattern

If it starts with a | then its sending the core to anther program. Make it leave a core on disk with:

echo 'core.%e.%p' > /proc/sys/kernel/core_pattern
