Write a script that uses 2 variables to store

You can have local variables with the same name in different functions, because each is recognized only by the function in which it is declared. Piping will be useful here. Instead of going to the next statement, the flow jumps to the body of the function, executes all the statements there, and then comes back to pick up where it left off.

These variables are called local variables. Place a comment before a line of code that previously worked, and record what happens when you rerun the program.

This will run as many mv commands as there are files in the current directory. It contains the local variables and parameters of the function. Download the example QVW and source data The only downside to this method is that the comments are not being written to the the comment section of the variable, but are instead stored together with the expression.

A statement that reads a module file and creates a module object.

Using Variables and Constants

One of the most useful features of programming languages is their ability to take small building blocks and compose them into larger chunks. Once you have defined a function, you can use it inside another function.

When executed, the exit status of a function is the exit status of the last command executed in the body. When the function is called, it prints the value of the parameter whatever it is twice.

Any redirections see Redirections associated with the shell function are performed when the function is executed. If you declare a variable outside a function, all the functions on your page can access it.

For example, it is easy to replace xargs to gzip all html files in the current directory and its subdirectories: A function definition specifies the name of a new function and the sequence of statements that execute when the function is called.

That sounds simple enough, until you remember that one function can call another. Multiplication and both Division operators have the same precedence, which is higher than Addition and Subtraction, which also have the same precedence.
