I'm trying to install the poweriso sh file (along with other sh files) onto my system, but it doesn't seem to work ( the outcome is the same on all sh files). I did some research on how to install sh files, various forums and youtube videos seem to conclude that I am in fact doing it right. but why isn't it installing? when I run
sudo chmod +x poweriso.sh
sudo chmod +x ./poweriso.sh
they gave me the same output, which is nothing, literally nothing, like I didn't even type anything. no error, nothing. what am I doing wrong?
