Hi, I tried
$ ppmrainbow -width 200 -height 20 -color blue -tmpdir=/tmp -verbose |xloadimage stdin Unknown option: color + pgmramp -lr 200 20 + pgmtoppm blue-blue + pnmcat -lr /tmp/000.ppm stdin is a 200x20 Raw PPM image with 256 levels Building XImage...done and I see that there is a file /tmp/000.ppm (which does not look good since it should be rather a tempfile) but this command does not end. I had to press <Ctrl>C to end the command and can confirm that /tmp/000.ppm remains when using netpbm version 10.0-15.4. When using netpbm from exprimental I get: $ ppmrainbow -width 200 -height 20 -color blue -tmpdir=/tmp -verbose |xloadimage stdin Unknown option: color + pgmramp -lr 200 20 + pgmtoppm blue-blue + pnmcat -lr /tmp/ppmrainbowCEUx/file.000.ppm stdin is a 200x20 Raw PPM image with 256 levels Building XImage...done which looks way better due to the usage of tempfile. This directory is removed afterwards so I think this bug can be closed with the next upload. Kind regards Andreas. -- http://fam-tille.de
