Sure, but to have the shell redirect /it's own/ input instead of the
input of it's sub-commands is counter-intuitive _and_ counter-
productive IMO. I like to write things like:
exec sh 5<&0 <<EOSH
exec 0<&5
vim "$0"
echo -n 'Edit OK? (yes/gigo)'
read a
if test "\$a" = yes ; then
"$0" "$@"
fi
exit 0
EOSH
which is fine if sh == ash...
...but this is OT. I'll try find a more appropriate forum.
L8r,
Buzz.
