Date: 2012jul5 OS: Linux Q. Linux: How can I quickly find all core files on my box? A. This is fast:

locate -r '^core\.'

It finds all files that begin with "core." as core files do. If your system is like most the database locate uses is only updated nightly so may be a bit out of date. But this is fine for a script that looks for old core files to delete them.
