A user wants to time a command/program/application and ensure the full contents of that command's data management has been flushed from RAM/cache and saved to disk. Is there a way to ensure the cache/RAM is flushed to disk, or is the flushing a function of the kernel or the application? This happens to be on a 64-bit Intel system with 64-bit CentOS 5, fully patched. But even if the system were an out-of-box 64-bit install, unpatched, would it make a difference? Thanks. Scott
