This! I was doing some work with a colleague and he was showing off some bash knowledge. I know a bit but my experience is limited since my last job was a Windows a shop.

We did a bunch of stuff with “xargs”. He said it was the one misunderstood command. One of the cool things was the ability to parallelize the work with a simple -P flag.

You do a find, make sure to use the -print0 flag, pipe it into xargs and use the -0 option then run a command over all the files. If you add -P it magically becomes parallel.
