What is PowerShell

Here, we'll learn about the advantages of utilizing PowerShell over Windows' built-in shells like the Command Prompt and batch files.

Both novices and experienced system administrators can take advantage of the functionality provided by the underlying operating system with the help of a shell. It's laid out like a command prompt, so you can manage your computer by typing in commands.

When compared to the Command Prompt and batch files, PowerShell offers numerous benefits. To give just a few examples:

In a batch script, each command is a single CMD command, thus you can only use those that are compatible with the Command Prompt. You can only automate simple activities with a batch script, but more complex jobs can be automated with a more robust scripting language like PowerShell, which supports variables, functions, classes, loops, error handling, and more.

Syntax highlighting, autocompletion, tabbed editing, and context-sensitive help are just some of the features included in PowerShell's Integrated Scripting Environment, or ISE, which makes scripting in PowerShell more simpler and more efficient than in the traditional Command Prompt.

Due to its foundation in the.NET Framework, PowerShell is a more robust command line interface (CLI) than CMD. PowerShell commands, also known as cmdlets, are runtime invocations of.NET classes. In addition,.NET languages like C# can be used to create cmdlets.

A cmdlet is a type of command used in PowerShell; however, behind the scenes, it is a.NET class that is invoked at runtime. In the.NET framework, C# and other languages can be used to create Cmdlets.

Aliases in PowerShell are shorthand for the built-in cmdlets, and they're meant to help people who are used to working in other shells (such the Command Prompt or Unix Bash) become productive in PowerShell quickly by renaming their most frequently used commands.

Fo instance; if you're familiar with CMD or Bash, you'll find that PowerShell's equivalent of the cd command—the Set-Location cmdlet—performs the identical function.

Here, "cd" is shorthand for "Set-Location," simplifying matters considerably. When you type rename in PowerShell, the Rename-Item cmdlet is actually being executed behind your back.

PowerShell is the preferred command line interface (CLI) for system administrators and other IT professionals since it contains all the functionality of CMD while also providing administrators with more robust cmdlets tailored to perform a wide range of administrative duties.

Third-party software vendors are extending PowerShell with custom cmdlets, such as the [NetApp PowerShell Toolkit]([https://community.netapp.com/t5/Microsoft-Virtualization-Discussions/NetApp-PowerShell-Toolkit-4-5P1-released/td-p/138566](https://community.netapp.com/t5/Microsoft-Virtualization-Discus

It's a good idea to learn PowerShell because it can be a marketable talent or even a necessity in some fields.

You could think the 'dir' command is same between the two interfaces, but in reality, they're really different.

PowerShell makes use of cmdlets, which are standalone pieces of code that reveal Windows' core administration features.

Like other shells, such as bash on Linux, PowerShell makes use of pipes to allow for the interprocess communication and sharing of input and output data across various commands. By connecting one cmdlet to another over a pipe, users can write sophisticated scripts that share data and parameters between commands. Users can develop scripts that can be reused to do automated or bulk modifications with arbitrary data, such as a list of servers. It is possible to create aliases for individual cmdlets in PowerShell. It is easier to move between shells when using aliases because the user can give their own names to the various cmdlets and scripts. Comparable to the 'dir' command in Windows, the 'ls' command in Linux bash displays directory objects. 'ls' and 'dir' are synonyms for PowerShell's 'Get-ChildItem' command.
