Hi,

Can someone tell me if this is a valid windows variable? %DISK_DRIVE% (I Found it in google, but not much is listed)

If so, could that be used in a batch file to copy/delete files? For example

copy file.ext %disk_drive%
delete file.exe %disk_drive%

Thanks

No idea. That's really ancient technology, I don't think you're going to find many people on a web forum who've used DOS variables in a long time.

Have you tried it? Just the copy statement? I don't think you need a second argument for delete?

I tried it this:

copy file.ext %disk_drive%:\

Which in my mind would be:

copy file.exe to any drive that exists...But I am pretty sure I am wrong...But I know it 'works' somewhat because I don't get an error message, just a blank where the drive letter 'should be' so the end result would be...

copy file.exe  :\

And of course the error renders out to be no drive specified, or something to that effect, but its not working and I want that to work.

Does it have to be a batch file?

No, it doesn't have to be a batch file

Anybody, when coding batch files can define Environment Variables which can be called in batch commands.

To see the standard ones, RC on "My Computer", choose Properties, open the Advanced tab and click the "Environment Variables ... " button.

From there you can edit them, delete them or create your own. Even in Windows XP you can edit autoexec.bat and define them there.

For the registry:
the System variables can be found in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment

and the user variables are in

HKEY_CURRENT_USER\Environment

Ok,

I guess I wasn't specific enough...

What I want to do is be able to copy / move / delete files across any hard drive on any of my pc's...So for example...If I had 3 computers with two hard drives in each machine, how could I copy files to all of those machines' hard drives in one shot? I was thinking that if I used some sort of file to accomplish this, that would make it automatic in the sense that I could run that file, and it's done. Instead of having to run it at each pc...

Thanks

It should be possible to do this using a batch file, it's basically a file replication or multiple backup routine that you need to write.

You would need to know the NETBIOS (WINS) names of the recipient machines and the target folder would have to be shared so the scripts could reference the UNC path to the folder \\MACHINE_NAME\SHARE_NAME

Why can you not process this the other way around and have the files on a network share with a mapped drive letter on the other machines?
That way there is only one copy to be updated.

Hey Chris,

How do you code an alert window in a batch file? For example to display a js message alert with the following in it. This would have to be in a batch file.

Operation Complete

Yep, that's what I am going to do

Thanks alot!

If the Messenger service is running you can do

net send MACHINE_NAME | USERNAME message

or you can use the pause command :

pause Operation Complete

this will output

C:> Operation Complete
Press any key to continue ...

at the command prompt.

I thought the idea of messenger popup window...But there's no way to do a javascript like this from a batch file?

alert ("This is a Javascript Alert")

Batch files don't run javascript. I think the technology is about 15 years older.

You mean a windows batch file couldn't do it using an array? Didn't think so, but I just thought may it *could* be done this way.
