Hi David, Glenn,
for command in true /bin/true; do
a=$( ( b=$( $command ); echo 123 >& 3; ) 3>& 1 ) &&
echo a=$a command=$command
done
a=123 command=true
a= command=/bin/true
Looks like a bug to me
This was originally reported on Stackoverflow:
"Why ksh disables stderr when subshell is executed?"
at http://stackoverflow.com/q/17398754/667820?sem=2
My very long analysis:
http://stackoverflow.com/a/21198338/667820
Only in the last couple of minutes did I see that we
can reproduce the effect without the functions.
The effect appears to be triggered by real subshells.
Cheers,
Henk
