Parallelizing Tasks in Unix/Linux

From Ian C. Blenke, The easiest way is with parallelized xargs:

$ find . -name '*.jpg' | sed -e 's/.jpg$//' | xargs -P4 -l1 -i
convert {}.jpg {}.png

The -P flag for xargs is a _wonderful_ thing to learn. Do it now, it
will forever save you time. I use it daily in our huge farm of linux
servers, makes for far more bearable adminning.
