chmod the file you just created to 0777 so you can actually run the dang thing (if you're a stickler for security use a lower setting)
So every time you see "chmod 0777" you know that the author turned all the permissions on without bothering which ones were needed. You might be suspicious of everything else they say as well.
Yes, yes, and only the sith deal in absolutes, exaggerate much? I don't mind doing 777s because I do all my security happens *way* before the individual PC, and then I double up that security by configuring the settings on the PC to aggressively control who can get onto the PC such that by the time you get onto the PC, I don't care if you can change/access stuff
Still that's exactly why I wrote

I leave it up to the user to do whatever they want to the settings
