Hello,

I have been encountering some issues while studying your work. Specifically, the prepare.sh script in the DIE-master/fuzz/scripts directory consistently gives me an error. The problem seems to be with the line echo performance | tee cpu*/cpufreq/scaling_governor because my system doesn't have the cpu*/cpufreq directory, although I do have the cpu0 and cpu1 directories. I made the following modifications to the code:

echo core

if [ -d ]; then
for cpu in do
echo performance | sudo tee "$cpu/scaling_governor"
done
elif [ -d ]; then
echo performance | sudo tee
fi

However, this modification is causing a "permission denied" error, even though I have used chmod +x prepare.sh. Could you please guide me on how to resolve these issues?


Thank you.
