Create Script to Compile and Execute Rust Programs

Create a file called rustrun in your /usr/local/bin directory that contains the following:

rustc $ && ./$1

This assumes you have installed bash on your system and that /usr/local/bin is in your PATH, which you can verify via:

$ echo $PATH

Then run:

$ sudo chmod u+x rustrun

Ensure that when your run ls -all rustrun you see:

-rwxr-xr-x  1 root  wheel  42 Feb 24 09:28 rustrun

If not, run sudo chmod +x rustrun

Then, when you are done writing your Rust program in whatever directory you're working in, you can just run

$ rustrun helloworld

Note: You don't need to include the .rs extension

Note: I changed the line to now read rustc $1 && ./${1::-3} which strips off the extension when running the executable. This now means you do need to add the .rs extension when running the command
