Script
The first thing we are going to do is define what a script is. This term comes from an English word that means "Script", like the one of cinema or theater and, literally, this is what it is. We have then, that a script, is a set of orders stored in a text file, usually very light and, that is executed in batches or line by line, in real time by an interpreter. Scripts are small programs that are not compiled, that is, they usually need a reader or interpreter program that encodes the information of the script and takes it to machine language, so that the information is processed and executed by the computer. The scripts are widely used to interact with the operating system of the computer, in an automated way. Although, many times, when we create programs with interpreted languages, such as Perl or Python, we are creating more complex scripts, which can perform any task or data management, as a compiled program, hence the enormous versatility of this programming resource. The scripts are widely used in the design and development of web pages and sites on the Internet, since they allow you to manipulate the appearance of these and create quite attractive special effects.
