I noticed after moving all my saved shell scripts from my external HD back onto my freshly reloaded laptop that they no longer had the same permissions as they did before. This in itself isn't too weird I guess, but the strange part is that I no longer need to make new scripts executable i.e. (chmod +x ...). Instead the scripts run just fine without the usual permissions. None of them have executable permission. Specifically they are all '-rw-r--r--'. So what gives?
