Thanks that's a very elegant batch process method and a brilliant resource link!

Maybe it's a bug which has been fixed. Can you ask Canonical/Ubuntu to update their version ? I have found a work around using this script: http://bash.cyberciti.biz/file-management/read-a-file-line-by-line/ and adding this line to the processLine() function: echo "mogrify -crop 300x300+0+0 -gravity ...

Isn't that what I tried in my original post? Edit... sorry yes this works: ross@ross-encoder:/media/media/240subset/test$ mogrify -crop 30x30+0+0 -gravity Center 00001.png 00002.png ross@ross-encoder:/media/media/240subset/test$ But how could put the list of images in at the end, from a text file?

I'm afraid this doesn't work either... ross@ross-encoder:/media/media/240subset/test$ mogrify -crop 30x30+0+0 @pics.txt -gravity Center mogrify: invalid argument for option `magick': -crop @ error/mogrify.c/MogrifyImageCommand/4546. ross@ross-encoder:/media/media/240subset/test$ ross@ross-encoder ...

Well this used to work. As I understood it, mogrify modifies an image (i.e. crop me.jpg) whereas convert requires both an input and output image file (i.e. convert me.jpg to me.png). Is it possible to do this with convert without generating another image file which I would have to find and remove ...

I have been using the following command successfully in the past but now it has stopped working: mogrify -crop 300x300+0+0 -gravity Center @picsToConvert.txt The picsToConvert.txt file contains: /media/media/0004_x264m_libschro/results/original/crop/00100.png /media/media/0004_x264m_libschro/results ...
