Hmmm... Sure it's failing? Maybe just the output is going somewhere
else? After the command runs, what does "echo $?" show? Does it even
work? Echo is a bash internal command, so I would expect it to never
fail.
What is your output device? A serial terminal? If so, could be simple
flow control issues. In fact, any serial connection (even a PC emulating
a terminal) could suffer from flow control problems. And they would tend
to be erratic in nature.
If you are on a normal console, try running the commands similart to
this (trying to determine if *something* else is receiving output or
not)
<your command> &> /dev/tty
if this works reliably, maybe that's a starting point.
There's a couple kernel guys who frequent this list. Maybe one of them
will have a clue as to what could go wrong. Corrupted libraries and
whatnot.
You might try that rpm -V command earlier against all packages (add a
"a" IIRC). Maybe some library accessed by the coreutils, but which is
not itself part of coreutils, is corrupt.
