If you know PowerShell, please write code for some of the tasks not implemented in PowerShell.
If you know PowerShell, please write code for some of the tasks not implemented in PowerShell.
PowerShell is a shell and scripting language released by Microsoft in 2006. Like other shells, PowerShell has a piping mechanism where the output of one command is passed as input to another command. However, unlike most shells, PowerShell passes objects rather than strings. This eliminates the text munging overhead usually necessary to make the pieces of a script fit together.
PowerShell is built on Microsoft's .NET framework and has full access to the CLR.
