Details:
I'd like to suggest the -P option be 'fixed' to be usable by itself.
If I use the -P option by itself I want xargs __ to try__ to use up to
"N" processors... Right now, it doesn't try at all unless you force
it to by using the -n/-l options.
That makes it sorta worthless...
I'd like to decide what is a good number of processes to run concurrently
for
a given "program" (that is to be run under xargs) and have xargs work out
the
rest.
I don't know what the total number of args is, so the only valid option,
most
of the time, is -n1.
I'd like to suggest that the program default to -n1 when -P is specified
alone --
making a -P option, by itself, "useful"...otherwise, my 'max' cpus values is
ignored and xargs will never use more than 1 cpu. That's certainly NOT
the intent if someone specifies "-P" by itself without "-n"...
Wouldn't this make sense?
yes?
thanks!
Linda
