Random GUID Filename

[Aegis]

I would like to rename a few thousand text files through batch to a randomly-generated GUID filename. Does anyone know how to do this? I'm thinking it might be possible by using a third-party command-line GUID generator and setting a variable to the program's output, then creating a FOR loop.

This is M$'s own GUIDGEN: http://www.microsoft.com/downloads/details...39-ADB270833AFC

Here's a command-line version: http://webhome.idirect.com/~jhonz/Utilities.HTM

There's a whole lot more of these things, just Google "guidgen" and you'll find moar.

Yes, I've found uuidgen.exe already. It outputs a single GUID without the brackets, so I redirected its output to a temporary file:

@echo off

:loop
uuidgen.exe > temp.dat
for /f %%i in (temp.dat) do set tempuuid=%%i
goto loop

That generates an infinite amount of GUID's for my use. My next step was to then call another batch file and do a "for" loop to rename all *.txt files to %tempguid%. That's when I first found out that "environmental variables" apply only to a single cmd.exe session. Any help is appreciated.
