A script is a series of commands or instructions written in a computer language. Scripts are used to perform a specific task and are usually interpreted or compiled.
Scripts can be written in many different programming languages. For example, Bash scripts are commonly used in Linux and Unix-based operating systems, while JavaScript scripts can be used in web browsers and server-side applications. Languages like Python, Perl, and Ruby are also commonly preferred for writing scripts.
Scripts are often used to automate a particular process or perform repetitive tasks. For instance, a system administrator can automate backup operations using a Bash script, or a web developer can control interactions on a web page using a JavaScript script.
Scripts are typically executed using an interpreter that interprets their source code or a compiler that runs them. In some cases, scripts can be executed directly from a command line or a text editor.
