check file is opened!!!

[cmancre]

This is the situation:

cp /path/file /path/file.new <---file got variable MB

During the copy (it will take some time) is there a way to check if file.new is completly or not completly copied?

IN PHP

if you are performing the file copy in php (and your code above indicates that you are doing it from a *nix shell), i believe that the script will pause until the file activity is finished.

You could use the filesize() function and compare the from and to files. If they are different it failed.
If you wanted another way to check even if the filesize were the same you could create some kind of check value aroubd MD5 or some kind of CRC (Cyclic Reduncancy Check) value
