[Sheflug] cpio people?

["Chris J" <cej [at] xxxxxxxxxxxxxxxx>]

'ello ... 

Is there anyone that uses cpio and knows enough about it to answer a quirk? 
Google so far hasn't helped :)

In essence, why does this work:

	find . -name 'rrn.*' | cpio -vH newc -o > bob

and this doesn't:

	ls -1 ./rrn.* | cpio -vH newc -o > bob

Something strange is going on; there are files named rrn.* in the directory 
as this shows ...

	[4397%][bubbles][tmp] >ls -1 ./rrn.*
	./rrn.10752.3
	./rrn.10752.4
	./rrn.10752.5
	./rrn.10752.6
	./rrn.10752.7
	./rrn.10752.8
	./rrn.10752.9
	./rrn.29355.2
	./rrn.29355.3
	./rrn.29355.4
	./rrn.29355.5
	./rrn.29355.6
	./rrn.29355.7
	./rrn.29355.8
	./rrn.29355.9
	[4398%][bubbles][tmp] >

however, when I pipe the results to cpio, it complains ...

	[4398%][bubbles][tmp] >ls -1 ./rrn.* | cpio -vH newc -o > bob

	cpio: : No such file or directory

Unlike find which does this instead...[first the results of find by 
itself]...

	[4399%][bubbles][tmp] >find . -name 'rrn.*'                
	./rrn.10752.9
	./rrn.10752.8
	./rrn.10752.7
	./rrn.10752.6
	./rrn.10752.5
	./rrn.10752.4
	./rrn.10752.3
	./rrn.29355.9
	./rrn.29355.8
	./rrn.29355.7
	./rrn.29355.6
	./rrn.29355.5
	./rrn.29355.4
	./rrn.29355.3
	./rrn.29355.2
	[4400%][bubbles][tmp] >

...and passing this to cpio...

	[4400%][bubbles][tmp] >find . -name 'rrn.*' | cpio -vH newc -o > bob
	./rrn.10752.9
	./rrn.10752.8
	./rrn.10752.7
	./rrn.10752.6
	./rrn.10752.5
	./rrn.10752.4
	./rrn.10752.3
	./rrn.29355.9
	./rrn.29355.8
	./rrn.29355.7
	./rrn.29355.6
	./rrn.29355.5
	./rrn.29355.4
	./rrn.29355.3
	./rrn.29355.2
	57 blocks
	[4401%][bubbles][tmp] >

... and lo and behold, I have a cpio archive. Now ... what the blazes is 
going on? In both cases, both find and ls are returning a single filename 
per line (which is what cpio is expecting)... but one is okay, whilst the 
other causes problems.

Hmm...
