Here's another example of magic failing:
% file t.sh
Downloads/temp swlap1
t.sh: ASCII text
% cat t.sh
Downloads/temp swlap1
max=10
echo "HERE 1"
for (( count = 0; count <= max; count++ )) ; do
echo "$count"
sleep "${sleep:-0}"
done
echo "HERE 2"
% ./t.sh
Downloads/temp swlap1
HERE 1
0
1
2
3
4
5
6
7
8
9
10
HERE 2
