[vox-tech] bash, short circuit logic, and errexit

Does everyone agree that the following script shouldn't last forever?
And if you agree, does it last forever nonetheless?


set -e

false && false;

while true; do
    echo "Still here"
    sleep 1


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.

bash 3.00.15(1)-release
