What's the use of this example? 🤔

To display what data xargs is receiving. It's also the simplest form of the command.

Yeah, it is technically the simplest, but it also does nothing. I mean, if you don't pipe to xargs, you'd get exactly the same output in the stdout, no? Or am I missing something?

Not exactly the same. All data is concatenated, separated by spaces even if the original data contains newlines

Still seems like something that other commands (e.g. sed, tr) would be more appropriate for than xargs IMHO.

I adjusted the description a bit so that it can be considered as a dry-run.

Oh hey, good question here: does --max-procs even do anything if --max-args isn't set?

I wouldn't focus on the "maximum" aspect here. By default xargs only spawns one process, and this bumps that number up, so the original description seems clearer. I agree with your choice of using parenthesis for the default, though. So: "Parallel runs of up to max-procs processes at a time (default is 1)."
As for --max-args, it seems like we might want to add {{[-n|--max-args]}} 1 here, yeah. But I'm not a xargs expert, so maybe others can help clarify if that makes sense.

Alright. I only assumed so since you've been prevalent in the history of this file.
