6 Features of PowerShell: (BSPTSW)

1. Background Job 2. Scheduled Job 3. PowerShell Remoting 4. Tab Expansion 5. Steppable Pipeline 6. Windows PowerShell ISE(Integrated Scripting Environment)

The following are the key features of Windows PowerShell ISE: (MSC)

1. Multiline Editing 2. Selective Execution 3. Context-Sensitive Help

There are four different types of execution policy in PowerShell: (RRUA)

1. Restricted 2. Remote Signed 3. Unrestricted 4. All Signed

- Only those scripts can be run, which are signed by a trusted publisher.

All Signed

-As a scripting language, PowerShell is commonly used for ________________ of systems. It is also used to build, test, and deploy solutions, often in CI/CD environments.

Automating The Management of systems.

- run scripts and cmdlets asynchronously on the remote and local machines in the background without affecting the user interface or interacting with the console. - runs a command without interacting with the current session.

Background Job

- Type the Invoke-Item and then press the f1 A help file opens to the article for an Invoke-Item command let.

Context-Sensitive Help

The first display of Monad was made in __________ at the ___________________ in 2003.

Los Angeles, Professional Developers Conference

- Microsoft started developing a new way of managing the command lines. It also included the development of a new Shell which was named _____________. (2002)

Monad

- In the command pane, to insert a blank line under the current line, press SHIFT + ENTER.

Multiline Editing

- file is a script, or "cmdlet," used by Windows PowerShell, a Windows shell program built on Microsoft's . NET Framework.

PS1

- allows the execution of cmdlets on remote systems which help to manage the set of remote computers from one single machine. - lets you run any Windows PowerShell command on one or more remote computers.

PowerShell Remoting

- a cross-platform task automation solution made up of a command-line shell, a scripting language, and a configuration management framework. - is a modern command shell that includes the best features of other popular shells. - commonly used for automating the management of systems.

Powershell

- In this policy, only those scripts are run, which are downloaded from the Internet, and these must be signed by the trusted publisher

Remote Signed

- In this policy, no script is executed.

Restricted

It is similar to the background job. Both the jobs execute asynchronously in the background without affecting the interface, but the main difference is that the background jobs are started manually

Scheduled Job

- To execute a part of a script, select the text to run, and click the Run script or press the F5 key.

Selective Execution

First, we set the execution policy to Unrestricted to execute the scripts by using the following command.

Set-Execution Policy Unrestricted

- This feature allows the splitting of script blocks into a ___________________. And then it gives the option to call the begin(), process(), and end() methods of script block to control the execution sequence. - a concrete form of metaprogramming, where one script has precise control over the sequence of operations in another.

Steppable Pipeline

- is an implementation of auto-completion, which completes the cmdlets, properties, and parameter names by pressing the Tab key once. - PowerShell provides completions on input to provide hints, enable discovery, and speed up input entry.

Tab Expansion

- All the scripts of Windows PowerShell are run.

Unrestricted

- It is the host GUI based application for the Windows PowerShell. - This feature provides tab completion, multiline editing, syntax coloring, context-sensitive help, selective execution, and support for right-to-left languages

Windows PowerShell ISE(Integrated Scripting Environment)

- The echo command has an alias named "__________" in Windows PowerShell Scripting language.

Write-Output

- is used to print the variables or strings on the console.

echo
