difficult GNU/Linux quiz (for people I haven't spoiled already): what is this program good for?

if [[ $? -ne 0 ]]; then
exit 255

Great question. Does it have something to do with things like letting xargs continue on a failure?

indeed. I lost 118 files recently because xargs continued on error and I didn't notice the output above. xargs stops itself entirely only when it gets exit code 255 from the subprocess.

I can't believe this isn't a command line option for xargs??
