I find the kcore file under /proc/ directory and it is huge.
I tried to delete it but I couldn't even with root privilege and I
got the below message:
rm: /proc/kcore: Operation not permitted.

Any one can explain me what kcore file is and how I can delete it.
I will appreciate it if you send me email or CC: ed to me.
Thanks, Joey

The items in the /proc directory are not disk files (and do not take
up any space on your harddrive), but kernel information.

The 'kcore' file is an image of your physical memory.

Typically it is also a BAD idea to delete things we don't understand. In
the future I would recommend asking before attempting to delete or you may
have a re-install issue.

Cheers,
Craig

Is this a troll?

You can't delete anything in the /proc hierarchy because none of those
things in there are files. They do not take up space on your disk.

/proc/kcore is the memory image your kernel is running in right now.
