All Lines starting with a # is a comment that is it will be neglected while the code is being executed.
The Second line there is "echo Enter Your Name" . echo is used to display  the Contents on the Screen & this works similar to the printf function in C Language
The Third there is read name . this will read a string from the user here we have used the word "name". This works similar to scanf statement of C language
The fourth line  will display the Name you entered.
