I have a batch file on Windows cmd that uses zbar to read barcode value in an image file and renames the image file with the barcode value. It works fine on a single image file when it is called with a specific image file name. Say the image file is "image.tif" and the batch file is "zbar.bat". I call "zbar.bat image.tif" and the "image.tif" is renamed with the barcode value contained in the image. But I have dozens of images to rename - each containing different barcode value. I would like to call the batch file on many image files in a folder so each file is renamed with the barcode value of a given image.
Here's the batch file derived from https://blog.jamesbayley.com/2016/05/04/extract-a-barcode-from-an-image-and-rename-the-file/

FOR /F "tokens=* USEBACKQ" %%F IN (`zbarimg -D -q %1`) DO (
SET fullbarcode=%%F
)
ECHO Full barcode: %fullbarcode%
ECHO ON
rename %1 %fullbarcode%.tif
Calling "zbar.bat *.tif" doesn't work. I'm wondering if there's a way to do that on multiple files. Say I have a folder with image files: 000000687.tif 000000688.tif 000000689.tif etc... Is there any way to process all the image files with the batch file so each image file is renamed?
