You don't need a shell script for this; just use the 'id' command look at the uid, which for root is 0.
Search Google with: "Linux semaphores" and have a look through the websites on the subject.
Apparently there is a draft of the script on the Internet Movie Script Database. Look at the link, below.
a shell
The answer is in the question. It documents the Linux computer operation system. Take a look at tldp.org
the internet
look in the shell
Put a skateboard in your place when your building or in ROBLOX Studio and then select the skateboard and thne look for the script.
Linux doesn't look like anything. It is a kernel upon which complete operating systems can be built. Each Linux operating system, known as a "distro", has its own unique appearance. Some of them are pretty spectacular and make mainstream OSes look like muck. Some look like gibberish spewed out of a teletype machine. Linux has this way of being just what you want, or, sometimes, almost-but-not-quite what you want. If you're not paying attention, it can even manifest itself as what you deserve. Linux is mutable.
outline with notes and narration
there are various websites. look up 'honk script', or ask, if youre in the play, the director.
Like a delicate sea shell, or a snail shell I guess.
