Does everyone agree that the following script shouldn't last forever?
And if you agree, does it last forever nonetheless?
----------
#!/bin/bash
set -e
false && false;
while true; do
echo "Still here"
sleep 1
done
---------
I discovered that 'diff -q $file1 $file2 && echo "no differences"'
wasn't ending my script, in spite of having 'set -e'. From the example
above, which does last forever, it looks like all short-circuit logic
confounds it.
