[bug #30504] bug/rfe....the "-P" option seems to be unusable by itself

[James Youngman]

Follow-up Comment #4, bug #30504 (project findutils):

That's why the documentation, at the moment, says this:

--max-procs=max-procs
-P max-procs

Run  up  to max-procs processes at a time; the default is 1.  If
max-procs is 0, xargs will run as many processes as possible  at
a  time.   Use the -n option with -P; otherwise chances are that
only one exec will be done.

If there is a consensus on the list for an alternative approach (for example
launching a child as soon as (fewer than max-procs children are executing) and
(at least one argument has not been consumed) then I'll consider working on
it.
