  Let make a simple script e.g. ~/unsharp.scm with content:

  (define (simple-unsharp-mask filename radius amount threshold)
     (let* ((image (car (gimp-file-load RUN-NONINTERACTIVE filename filename)))
            (drawable (car (gimp-image-get-active-layer image)))
            (buffer (vector ""))
            (output "/app/"))
       (plug-in-unsharp-mask RUN-NONINTERACTIVE
                         image drawable radius amount threshold)
       (re-match "([^/]+)$" filename buffer)
       (set! output (string-append output (substring filename (car (vector-ref buffer 0)))))
       (gimp-file-save RUN-NONINTERACTIVE image drawable output output)
       (gimp-image-delete image)))
  

  Copy

  Then run command:

  docker run --rm -v `pwd`:/app -w /app -v ~/unsharp.scm:/gimp/scripts/unsharp.scm minidocks/gimp \
      -i -b '(simple-unsharp-mask "/usr/share/gimp/3.0/images/gimp-splash.png" 5.0 0.5 0)' -b '(gimp-quit 0)'
  

  Copy
