A shell script is a file that contains a list of commands to be read and executed by the shell in Linux and macOS. A .sh file is used for a shell script and its first line always begins with #!/bin/bash that designates the interpreter. This line instructs the operating system to execute the script. Shell scripts allow you to perform various functions. These functions include automation of commands and tasks of system administration and troubleshooting, creating simple applications, and manipulating text or files. Python is a general-purpose programming language that can develop many different kinds of applications. It is designed to be easy to read, and the programs use fewer lines of code compared to other programming languages. The code runs in an interpreter. Python is preinstalled on many Linux distributions and can be installed on Windows. Python scripts are saved using the .py extension. VBScript is a scripting language based on Microsoft’s Visual Basic programming language. Network administrators often use VBScript to perform repetitive administrative tasks. With VBScript, you can run your scripts from either the command-line or the Windows graphical interface. Scripts that you write must be run within a host environment. Windows 10 provides Internet Explorer, IIS, and Windows Script Host (WSH) for this purpose. Batch scripts run on the Windows operating system and, in their simplest form, contain a list of several commands that are executed in a sequence. A .bat file is used for a batch script. You can run the file by calling its name from the command line or double-clicking the file in File Explorer. Generally, batch file scripts run from end to end and are limited in branching and user input.
