I'm lost.  I thought it was the redirection of `cd' which was wrong,
and though it would be the same for all builtins...  So indeed I
understand that echo is not a builtin, but exit must be a builtin, and
it does not show the `illegal io' message :(

I'm a bit lost here.

foo=`cd / 2>/dev/null`
echo ,$foo,

bar=`cd /foo 2>/dev/null`
echo ,$bar,

baz=`exit nonsense 2>/dev/null`
echo ,$baz,



Maybe `exit' has no error message at all?

exit nonsense



What builtin could issue message?  If someone understands what
happens, please speak up!


Thanks Harlan!
