PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.

The directory stack underlies the functions of these two commands. It is an array of paths stored as an environment variable in the CLI, which can be viewed using the command dirs in Unix or Get-Location -stack in PowerShell. The current working directory is always at the top of the stack.
Windows Script Files have the extension ".WSF". A WSF makes reference to each script module in a very basic XML hierarchy as shown below, adhering to those standards outside the <script> tags. Literal use of "</script>" or "<script>" inside your <script> tags and similar challenges can be handled by the use of CDATA, as shown within the examples.
In PowerShell, all types of commands (cmdlets, functions, script files) inherently expose data about the names, types and valid value ranges/lists for each argument. This metadata is used by PowerShell to automatically support argument name and value completion for built-in commands/functions, user-defined commands/functions as well as for ...
Windows PowerShell, Microsoft's object-oriented command line shell and scripting language, executes the cd command (cmdlet) within the shell's process. However, since PowerShell is based on the .NET Framework and has a different architecture than previous shells, all of PowerShell's cmdlets like ls, rm etc. run in the shell's process. Of course ...
In this model, scripts would only behave as other commands if called from within a Bourne shell. An attempt to directly execute such a file via the operating system's own exec() system call would fail, preventing scripts from behaving uniformly as normal system commands.
In computing, a script is a relatively short and simple set of instructions that typically automate an otherwise manual process. The act of writing a script is called scripting . A scripting language or script language is a programming language that is used for scripting.
In addition, the shell's command-searching was enhanced to allow shell procedures to be invoked like binary commands, i.e., if the shell found a non-binary file marked executable, it would fork another shell instance to read that file as a shell script. Thus people could type command arguments rather than sh pathname/command arguments.
