PowerShell is an object-oriented programming language and interactive command line shell for Microsoft Windows. PowerShell was designed to automate system tasks, such as batch processing, and create systems management tools for commonly implemented processes. The PowerShell language is similar to Perl.
A cmdlet (pronounced “command-let”) is a lightweight Windows PowerShell script that performs a single function.
A command, in this context, is a specific order from a user to the computer’s operating system or to an application to perform a service, such as “Show me all my files” or “Run this program for me.” Although Windows PowerShell includes more than two hundred basic core cmdlets, administrators can also write their own cmdlets and share them.
A cmdlet, which is expressed as a verb-noun pair, has a .ps1 extension. Each cmdlet has a help file that can be accessed by typing Get-Help CmdletName-Detailed. The detailed view of the cmdlet help file includes a description of the cmdlet, the command syntax, descriptions of the parameters and an example that demonstrate use of the cmdlet.
Popular basic cmdlets include:
| Cmdlet | Function |
| Get-Location | get the current directory |
| Set-Location | change the current directory |
| Copy-Item | copy files |
| Remove-Item | remove a file or directory |
| Move-Item | move a file |
| Rename-Item | rename a file |
| New-Item create a new empty file or directory | create a new empty file or directory |
