Hi, all:
When I was doing some testing I found the file descriptor 10 is always
duplicate of fd 0 and it cannot be closed.
See the following commands:
# echo $BASH_VERSION
3.2.39(1)-release
# read line 10
hello--- input from keyboard
# echo $line
hello
# exec 10---- try to close fd 10

You haven't opened file descriptor 11:
$ (
exec 11$HOME/.bashrc
while read 11
do
printf .
done
echo
exec 11-
)
