Hello all, I am totally new to rust / rustup. I purchased a book on the subject which arrived yesterday znd set to work. The first program, naturally, is hello world. I followed the book letter by letter and when I tried to run the program, called main.rs, nothing happened. I will try to attach the terminal here. (I am using ubuntu 16.04).
rod@rod:~$ cd projects
rod@rod:~/projects$ cd hello_world
main.rs: command not found
As you can see, the main.rs exists but when I try to open it, I am told command not found even though it shows in the ls-l (List).
Being totally new to this, could you perhaps show me where I have gone wrong.
