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?
Besides sync, look for sync at mount manpage, sync or write in chattr manpage as well as man fsync, fdatasync
Also, for timing programs, kernel documentation of /proc/sys/vm/drop_caches in filesystems/proc.txt will be useful.

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.
