Script needed to check for file, rename and then copy a file

[tosca925]

I am useless at scripts but need someone to help me out. I need a script to run in a GPO on computer start up.

 

I need it to check for a file in systems 32, ie, c:\windows\system32\file.dll.

 

If it exists i need the script to rename the file to oldfile.dll.

 

Then the script needs to copy a new file.dll to the same location from a folder on the server.

 

 

 

Could anyone please help me.

Try This

 

::____________Start Script______________________
:: check if oldfile.dll exists, if so script has already run
if exist "%windir%\system32\oldfile.dll" goto :EOF
:: if oldfile.dll does not exist and file.dll does exist then we need to act
if exist "%windir%\system32\file.dll" rename "%windir%\system32\file.dll" oldfile.dll
:: now copy the new file from the server
copy "\\server\share\file.dll" "%windir%\system32\file.dll"
@echo Job Completed
::____________End Script______________________

beware of the word wrap, the orphaned oldfile.dll on line 6 belongs on the end of line 5

Me again, there are lots of word wrap issues in that code, copy and paste seems to make it OK but just in case I have attached the file to this post. You will need to change the extention to cmd - but you knew that anyway (I just can't upload .cmd files)

Windows System File Protection will eat you alive.

Only partly true, if it is a system dll then I agree, if it is a dll put there by a 3rd party app then probably not - I have not seen many of them go to the bother of protecting their dlls.

 

However our school is mostly w2k and the age of most of the software reflects that environment so I may well be wrong about this specific case.

 

If the file is under the protection of sfp then I agree that the job becomes a little more problematic than the would be addressed by the simple script that I offered but it does what was asked for (I think) and if more is actually needed we can look at that after Tosca has tried it in his environment.
