It’s been forever since I posted a comment here, and just was reminded of this post when I was going through bookmarks.

Check out GNU Parallel for doing exactly this, and so much more! http://www.gnu.org/software/parallel/

afaik, “treat each line as one input” is the default mode of xargs. “do one at a time” is -n1. the intended purpose of -0 is to change the notion of a “line” from newline-termination to null-termination, so that files with newlines in their names can be processed properly.

I think you want runN (http://aaroncrane.co.uk/2008/07/runN/). It’s, I think, exactly what you were looking for. (Look at the bottom of the blog post for a link to the source).

I’ve faced similar issues in the past. A couple of points,

—-
Dont pipe from ls, instead do:
for i in *; do echo $i ; done

—-
Use GraphicsMagick ( http://www.graphicsmagick.org/ ) instead of ImageMagick.
