what a difference between cmd and powershell at windows

CMD (Command Prompt) and PowerShell are two command-line interfaces available in Windows operating systems. While they both allow users to interact with the operating system via the command line, there are some differences between them:


Syntax: PowerShell uses a different syntax than CMD. PowerShell uses cmdlets, which are pre-built commands with a consistent verb-noun syntax. CMD uses commands that are typically shorter and simpler.


Object-Oriented: PowerShell is object-oriented, which means that it allows users to manipulate objects directly. CMD, on the other hand, is a text-based interface that requires users to parse text output to manipulate data.


Scripting: PowerShell has more advanced scripting capabilities than CMD, including features such as loops, variables, and error handling. PowerShell scripts can also be easily run from the command line.


Integration: PowerShell is integrated with the .NET framework, which allows users to take advantage of its powerful features such as XML and database support. CMD does not have this level of integration.


Compatibility: CMD is compatible with older operating systems such as Windows 95 and 98, while PowerShell is only available on newer versions of Windows.


Security: PowerShell includes advanced security features such as execution policies, which help prevent malicious scripts from being run on a system. CMD does not have these features.


In conclusion, PowerShell is a more advanced and object-oriented command-line interface than CMD. It provides more advanced scripting capabilities, integration with .NET framework, and security features. However, CMD is still available in newer versions of Windows and may be more familiar to users who have experience with older operating systems.
