I'm not sure wether I'm understanding the problem correctly (I
didn't the complete thread), but if all you need is a yes for a
shell script when there's no yes(1) is installed, you could just
use a small function:
yes() {
local x=$1
x=${x:=y}
while :; do; echo "$x" done
}
Or if you just need to create some output (as seems to be the case
in issue1017_whatsnew_stack.sh):
typeset -i x
x=4000
while [ $x -gt 0 ]; do
echo y
let x--
done > foo
