So i tried to run the batch code from this tutorial: http://www.gimp.org/tutorials/Basic_Batch/

I copied and saved this to the .gimp-2.8 scripts folder

  (define (batch-unsharp-mask pattern
                              radius
                              amount
                              threshold)
  (let* ((filelist (cadr (file-glob pattern 1))))
    (while (not (null? filelist))
           (let* ((filename (car filelist))
                  (image (car (gimp-file-load RUN-NONINTERACTIVE
                                              filename filename)))
                  (drawable (car (gimp-image-get-active-layer image))))
             (plug-in-unsharp-mask RUN-NONINTERACTIVE
                                   image drawable radius amount threshold)
             (gimp-file-save RUN-NONINTERACTIVE
                             image drawable filename filename)
             (gimp-image-delete image))
           (set! filelist (cdr filelist)))))

And ran the command:

gimp-2.8 -i -b '(batch-unsharp-mask "*.png" 5.0 0.5 0)' -b '(gimp-quit 0)'

But i get the error

Error: ( : 1) eval: unbound variable: *.png

This doesn't seem to be a problem with the script; probably the way i am calling it or i am missing something but i cant figure it out.

I know it's been four long months, but I was just fighting with a gimp (2.8) script I had written and getting a recurring

batch command experienced an execution error:
Error: ( : 32578) eval: unbound variable: while

It turns out that, in my haste to consolidate script directories, I had removed the reference to /usr/share/gimp/2.0/scripts. Apparently there's something in that directory that defines "while"

Got the original script working in gimp 2.8 ubuntu 14.04lts Just had to copy and paste the line breaks back together. I am having trouble pasting this in so the lines are not broken, just remove the blank lines as they are a posting anomaly. Place script in ~/.gimp-2.9/scripts Using this to remove haze run as gimp -i -b '(batch-unsharp-mask "*.JPG" 100 0.3 0)' -b '(gimp-quit 0)'

(define (batch-unsharp-mask pattern radius amount threshold)
(let* ((filelist (cadr (file-glob pattern 1))))
(while (not (null? filelist))
  (let* ((filename (car filelist))
  (image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
  (drawable (car (gimp-image-get-active-layer image))))
  (plug-in-unsharp-mask RUN-NONINTERACTIVE  image drawable radius amount threshold)
  (gimp-file-save RUN-NONINTERACTIVE image drawable filename filename)
  (gimp-image-delete image))
(set! filelist (cdr filelist)))))

I resolved this error by confirming the name of my script. I copied my script from an existing script and the name was duplicate. After I updated the name of my script the error went away and everything started working.

You must have unique script names, that includes the define name

What helped me was making sure that the script had the correct extension, .scm.

Had the same problem with a similar batch script. The only way I was able to make it work was to remove the pattern from the command line entirely and hard code it in the script itself.

This is what worked for me:

from:

(define (batch-c2c pattern)
(let* ((filelist (cadr (file-glob pattern 1))))

to:

(define (batch-c2c)
(let* ((filelist (cadr (file-glob "*.png" 1))))

command line: gimp-2.10 -i -b "(batch-c2c)" -b "(gimp-quit 0)"
