The Linux and UNIX operating systems were built on shell scripting within its operating system, it’s the beating heart of the operating system. “Scripting is a way by which one can alleviate this necessity by automating these command sequences in order to make one’s life at the shell easier and more productive. Scripting is all about making the computer, the tool do the work” (The University of Birmingham, 2005). When working with a shell scripting program, there are several advantages to it. One of the first advantages is its ease of use. Another advantage is its quick start and interactive debugging. The most notable and major advantage for the use of shell scripting is it’s a time-saving tool for system administrators for the automation of tasks. By using the shell script, administrators are able to compile and automate task system wide and alleviating the need to access each workstation individually. Shell scripts can execute without any additional effort on nearly any modern UNIX / Linux / BSD / Mac OS X operating system as they are written an interpreted language. According to Microsoft’s TechNet website (2013), “Windows PowerShell® is a task-based command-line shell and scripting language designed especially for system administration. Built on the .NET Framework, Windows PowerShell helps IT professionals and power users control and automate the administration of the Windows operating system and applications that run on Windows”. The most common usages for Windows PowerShell are the “interactive console (powershell.exe) and script files (with extension of .ps1, which is also usually executed by powershell.exe). Main features of PowerShell are: .Net integration, object pipeline, easy access to many management domains (WMI, ADSI, COM, .NET etc.) and standardization that brings easy discovery and quick learning of new features after you know base functionality” (Microsoft Corporation, 2014).
