Type cat > foo ( then return)
(type) test 123 (then return)
(type) control -D

Umm, you were supposed to look at the contents of the file "foo" to see if it got what you typed.

hexdump -C foo

some lib ?

Now, if cat << EOF works... then we can say, it must be the combind,
download to update to 10.3.9 that has a problem..
so I will break it down, until it breaks.

or,
if the cat command is broken right at the start, then
I need to call Apple.

1) This sounds like an interesting plan - it will tell you if the problem arose with a particular OS X update.

2) But before you do that, please boot into single-user and see if the problem exists there.

3) I don't think your hardware is supported by Apple, so I don't imagine you will get much joy that way. Besides which, it is out of warranty so I think you will have to pay to get tech support from Apple.

4) Speaking of the hardware, it would be nice to rule that out as the problem - that is why I suggested mounting your disk on some other Mac and running your copy of bash on that other Mac.

Well, I was right, :D
The cat test work just fine on 10.3 with NO updates...
running in bash

ie.

=========
as you can see...
my guess, there a corrupt lib in the combind update (10.3.9)
I will download the combine to 10.3.3 and test that first,
see where it breaks.

We know, for a fact ,if I did a full updated, via software update,
it will break ALL the time. So again, something in the FULL 10.3.9 update,
is corrupted.

-R
