Description Jonathan 2016-12-26 22:53:33 UTC 
A critically needed feature I use a lot is GNU xargs parallel operations. Often the parallel xargs operations are better than the cli util "parallel" for my use-cases. 

Example:
find samplegz | xargs -n1 -P4 sh parse.sh

P4 says have at most 4 commands running at the same time
