Cmdlet vs Command

Cmdlets are way different from commands in other command-shell environments in the following manners −

  • Cmdlets are .NET Framework class objects; and not just stand-alone executables.

  • Cmdlets can be easily constructed from as few as a dozen lines of code.

  • Parsing, error presentation, and output formatting are not handled by cmdlets. It is done by the Windows PowerShell runtime.

  • Cmdlets process works on objects not on text stream and objects can be passed as output for pipelining.

  • Cmdlets are record-based as they process a single object at a time.

Cmdlet

New-Item cmdlet is used to create a directory by passing the path using -Path as path of the directory and -ItemType as Directory.

New-Item -Path '/home/kali/test' -ItemType Directory 
New-Item -Path '/home/kali/test' -ItemType File

Copy-Item cmdlet is used to copy a directory by passing the path of the directory to be copied and destination path where the folder is to be copied.

 Copy-Item 'C:\Users\H3ckt0r\Desktop\Test\test' 'C:\Users\H3ckt0r\Downloads\'

Remove-Item cmdlet is used to delete a directory by passing the path of the directory to be deleted.

 Remove-Item  'C:\Users\H3ckt0r\Desktop\Test\test'

Move-Item cmdlet is used to move a directory by passing the path of the directory to be moved and destination path where the folder is to be moved.

 Move-Item  'C:\Users\H3ckt0r\Desktop\Test\test'

Rename-Item cmdlet is used to rename a folder by passing the path of the folder to be renamed and target name

Rename-Item  'C:\Users\H3ckt0r\Desktop\Test\test'  'C:\Users\H3ckt0r\Desktop\Test\test1'

Get-Content cmdlet is used to retrieve content of a file as an array.

Get-Content 'T:\Users\H3ckt0r\Downloads\cacert.der'
