for (i in 1 2 3) {
q=$i^bar
echo $q $i
}
produces output
1bar 1
2bar 2
3bar 3
as we expect. This is good. However,
for (i in 1 2 3) {
q=$i^bar
cat << EOF
$i $q
EOF
}
produces
3 3bar
3 3bar
3 3bar
which was not what I expected. I expected the outputs to be the same.
Was I expecting the right thing or the wrong thing?
The night is pleasing to us because, like memory, it erases idle details.
