Writing a batch file... Need a variable.?

Question

For a batch file, how do you get it to prompt you for a drive letter?

And within the batch file, what variable string do I use to propogate the supplied drive letter?

Answer 1

There is no pre-defined variable string for the drive letter.  You use whatever string you've read the drive letter into.

SET /P driveletter="Enter a drive letter.  "

REM do something with that drive:

dir %driveletter%:\

Hope that helps.

Answer 2

You don't specify the OS, which would help.

If you are using XP, try

Windows 2000/XP

In Windows 2000, user input can be obtained quite easily by using SET /P

SET /P variable=[promptString]

This command will display an optional promptString where the user can type in a string and press Enter. The typed string will then be stored in the specified environment variable variable.

Answer 3

set /P variable=promptstring

Example: set /P drv="Please enter a drive letter: "

To see the results, simply: echo %drv%
