Batch reading the label of volumes

Hi all,

I need a batch file that will read the label of each volume. I really **** at batch files and any help is appreciated.

somthing like:

loop through volumes (e.g., a:\, c:\, d:\, e:\, etc...)
if volume.label == "USBdrv" then
set variable = volume (e.g., e:\)
endif
next

 

It's not easy with a batch (not impossible but far from easy).

Would a small exe file do you? I could whip up a dos exe in a couple of hours if you like?

EDIT:
If you'd prefer the batch route then a couple of pointers

FIND (pipe from DIR)
ERRORLEVEL
FOR

 

OK here's what I have up till now...

Code:

@echo off
if not  "%1" == " " goto checkvol
FOR %%v IN (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) DO call %0 %%v
:checkvol
VOL %1: | FIND /I  "Volume in drive %1 is SYSTEM" > nul
IF not ERRORLEVEL 1 set THEUSB=%1:\

It works but it's ugly, can't recall if it's possible to redirect STDERR in dos batch commands (I'll leave that to you)

Change the SYSTEM in line 5 to whatever you're looking for and the THEUSB (line 6) to the environment variable you require.

A couple of caveats, all volumes in the list (line 3) are checked so only the last one with the label you look for will be set...

ie if I had a system vol on C and D the variable would be set as D. This can be changed to the first matching label if required.

If no matching volume is found then any previous setting for the variable is kept, you may wish to clear the variable between the IF NOT and FOR.

Let me now if that's enough for you or if you want to use exe's

EDIT: Changed DIR to VOL (I can't beleive I forgot that command, senality setting in )

Anyway the change will prevent unlikely issues with DIRCMD settings.
