May be create a file name core with permission --------- or r-------- or link of core to /dev/null

core -> /dev/null

# ll core
-r-------- 1 root sys 0 Apr 26 16:12 core
# ll core
lrwxrwxrwx 1 root sys 9 Apr 26 16:13 core -> /dev/null

Probably the best way is to a ulimit -c 0 in the user's .profile. On second thought, THE BEST WAY is to fix the code so that it does not dump core.

Anu,

To prevent the creation of core files in unix requires a developer to insure that their program doesn't do stupid things like: failing to do adequate error checking, failure to make sure resources are available before consuming them, and failure to trap error conditions or potential error conditions.

Basically, you can't prevent them, but you can do a few things. One, just delete them. Two, report the core file creation to the responsible party whose software caused it to happen.

To have an idea about the core type "# file core" here's a good discussion "How can I analyze a core file? ":
