Initially a Windows component only, Power. Shell was made open- source and cross- platform on 1. August 2. 01. 6. Sets of cmdlets may be combined into scripts, executables (which are standalone applications), or by instantiating regular . NET classes (or WMI/COM Objects). Power. Shell also provides a hosting API with which the Power. Shell runtime can be embedded inside other applications. These applications can then use Power. Shell functionality to implement certain operations, including those exposed via the graphical interface. This capability has been used by Microsoft Exchange Server 2. Power. Shell cmdlets and providers and implement the graphical management tools as Power. Shell hosts which invoke the necessary cmdlets. Local help contents can be retrieved from the Internet via Update- Help cmdlet. Alternatively, help from the web can be acquired on a case- by- case basis via the - online switch to Get- Help. Background. These are COMMAND. COM (in installations relying on MS- DOS, including Windows 9x) and cmd. Windows NT family of operating systems). The shell is a command line interpreter that supports a few basic commands. For other purposes, a separate console application must be invoked from the shell. The shell also includes a scripting language (batch files), which can be used to automate various tasks. However, the shell cannot be used to automate all facets of GUI functionality, in part because command- line equivalents of operations exposed via the graphical interface are limited, and the scripting language is elementary and does not allow the creation of complex scripts. In Windows Server 2. It integrates with the Active Script engine and allows scripts to be written in compatible languages, such as JScript and VBScript, leveraging the APIs exposed by applications via COM. However, it has its own deficiencies: it is not integrated with the shell, its documentation is not very accessible, and it quickly gained a reputation as a system vulnerability vector after several high- profile computer viruses exploited weaknesses in its security provisions. Different versions of Windows provided various special- purpose command line interpreters (such as netsh and WMIC) with their own command sets. None of them were integrated with the command shell; nor were they interoperable. By 2. 00. 2 Microsoft had started to develop a new approach to command line management, including a shell called Monad (also known as Microsoft Shell or MSH). The shell and the ideas behind it were published in August 2. Monad Manifesto. Microsoft first showed off Monad at the Professional Development Conference in Los Angeles in October 2. A private beta program began a few months later which eventually led to a public beta program. Microsoft published the first Monad public beta release on June 1. Beta 2 on September 1. Beta 3 on January 1. Not much later, on April 2. Microsoft formally announced that Monad had been renamed Windows Power. Shell, positioning it as a significant part of their management technology offerings. A significant aspect of both the name change and the RC was that this was now a component of Windows, and not an add- on product. Release Candidate 2 of Power. Shell version 1 was released on September 2. Release to the web (RTW) on November 1. Tech. Ed Barcelona. Power. Shell for earlier versions of Windows was released on January 3. During the development, Microsoft shipped three community technology preview (CTP). Microsoft made these releases available to the public. The last CTP release of Windows Power. Shell v. 2. 0 was made available in December 2. Versions of Power. Shell for Windows XP, Windows Server 2. Windows Vista and Windows Server 2. October 2. 00. 9 and are available for download for both 3. It is distinct from . Power. Shell provides an interactive command- line interface, wherein the commands can be entered and their output displayed. The user interface, based on the Win. Power. Shell enables the creation of aliases for cmdlets, which Power. Shell textually translates into invocations of the original commands. Power. Shell supports both named and positional parameters for commands. In executing a cmdlet, the job of binding the argument value to the parameter is done by Power. Shell itself, but for external executables, arguments are parsed by the external executable independently of Power. Shell interpretation. For example, it enables the creation of different views of objects by exposing only a subset of the data fields, properties, and methods, as well as specifying custom formatting and sorting behavior. These views are mapped to the original object using XML- based configuration files. These are the native commands in the Power. Shell stack. Cmdlets follow a Verb- Noun naming pattern, such as Get- Child. Item, helping to make them self- descriptive. But whereas Power. Shell allows arrays and other collections of objects to be written to the pipeline, cmdlets always process objects individually. For collections of objects, Power. Shell invokes the cmdlet on each object in the collection, in sequence. Cmdlets derive either from Cmdlet or from PSCmdlet, the latter being used when the cmdlet needs to interact with the Power. Shell runtime. Whenever a cmdlet runs, Power. Shell invokes these methods in sequence, with Process. Record() being called if it receives pipeline input. The class implementing the Cmdlet must have one . NET attribute – Cmdlet. Attribute – which specifies the verb and the noun that make up the name of the cmdlet. Common verbs are provided as an enum. Power. Shell invokes the mutator with the parameter value or pipeline input, which is saved by the mutator implementation in class variables. These values are then referred to by the methods which implement the functionality. Properties that map to command- line parameters are marked by Parameter. Attribute. Those which map to pipeline input are also flanked by Parameter. Attribute, but with the Value. From. Pipeline attribute parameter set. In addition, Power. Shell makes certain APIs available, such as Write. Object(), which is used to access Power. Shell- specific functionality, such as writing resultant objects to the pipeline. Cmdlets can use . NET data access APIs directly or use the Power. Shell infrastructure of Power. Shell Providers, which make data stores addressable using unique paths. Data stores are exposed using drive letters, and hierarchies within them, addressed as directories. Windows Power. Shell ships with providers for the file system, registry, the certificate store, as well as the namespaces for command aliases, variables, and functions. Other applications can register cmdlets with Power. Shell, thus allowing it to manage them, and, if they enclose any datastore (such as databases), they can add specific providers as well. The Power. Shell V2 release notes state. Code from a module executes in its own self- contained context and does not affect the state outside of the module. Modules also enable you to define a restricted runspace environment by using a script. For example, the output of the Get- Process cmdlet could be piped to the Where- Object to filter any process that has less than 1 MB of paged memory, and then to the Sort- Object cmdlet (e. Select- Object cmdlet to select just the first 1. However, the Power. Shell pipeline differs from Unix pipelines in that stages execute within the Power. Shell runtime rather than as a set of processes coordinated by the operating system, and structured . NET objects, rather than byte streams, are passed from one stage to the next. Using objects and executing stages within the Power. Shell runtime eliminates the need to serialize data structures, or to extract them by explicitly parsing text output. In addition, Power. Shell allows formatting definitions to be specified, so the text representation of objects can be customized by choosing which data elements to display, and in what manner. However, in order to maintain backwards compatibility, if an external executable is used in a pipeline, it receives a text stream representing the object, instead of directly integrating with the Power. Shell type system. The scripting language supports variables, functions, branching (if- then- else), loops (while, do, for, and foreach), structured error/exception handling and closures/lambda expressions. Variables in Power. Shell scripts are prefixed with $. Variables can be assigned any value, including the output of cmdlets. Strings can be enclosed either in single quotes or in double quotes: when using double quotes, variables will be expanded even if they are inside the quotation marks. Enclosing the path to a file in braces preceded by a dollar sign (as in $. If it is used as an L- value, anything assigned to it will be written to the file. When used as an R- value, the contents of the file will be read. If an object is assigned, it is serialized before being stored. Power. Shell provides special variables, such as $args, which is an array of all the command line arguments passed to a function from the command line, and $. The Power. Shell scripting language also evaluates arithmetic expressions entered on the command line immediately, and it parses common abbreviations, such as GB, MB, and KB. Objects are created using the New- Object cmdlet. Calling methods of . NET objects is accomplished by using the regular . A string enclosed between single quotation marks is a raw string while a string enclosed between double quotation marks is an escaped string.
