Top Forums Programming Difference between cp and mv linux command Post 302425555 by DreamWarrior on Friday 28th of May 2010 11:59:14 AM

As for your question. I believe calling fsync has nothing to do with the directory structure, which is entirely up to the file system modules in the kernel. So, I would guess when you mv and power off, the file system has not had a chance to flush its changes. As such, you lose the modifications it made to the directory structure. When you cp the file, it may flush the changes more immediately as it is creating a new file.... This is just a guess.... However, I do not believe your fix lies in the program you are writing, because I am not sure you can programatically control when the file system changes get flushed to disk.
