Bulk Thumbnailing from the command line

[kde-head]

Requirements: ImageMagick

(urpmi imagemagick should install it for you)

 

If you have a directory of large jpg images that you want to mass thumbnail down to say , 120 pixel wide thumbs, just issue to the following command from the konsole:

 

ls -1 *.jpg | sed "s/\(.*\)\.jpg/\1.jpg \1_thumb.jpg/" |xargs -n 2 convert -resize 120 -quality 100 -compress JPEG

 

 

 

This creates 120 pixel wide thumbs of your images , all with the extension "_thumb.jpg"
