This sounds a lot like a permissions issue.  When you save the "second" file, you're saving it with permissions 0644 by default, with your user/group, at least on *nix.  If you want, post the the output of ls -l file1 file2 before you do the rename, and I can give you a better answer.

As for permissions, try changing the permissions on the original file by using chmod:

chmod 0644 &lt;file&gt;


php scripts run only after renaming
According to the Skyrim Wiki, "daggers are silent, meaning that enemies are not alerted to your dagger swings, even missed ones." However,  there is generally a sound (grunt or guttural throat noise) to go along with a power attack animation.

Is this noise just for effect (like the passive spell-in-hand glow) or is the sound audible by potential victims/enemies?
