In PowerShell, piping is a way to pass the output of one command as the input to another command. This allows you to chain multiple commands together and perform complex operations in a single line of code.

The piping operator in PowerShell is |, which is also known as the “pipe” symbol. To use piping, you can place the | symbol between two commands, like this:

command1 | command2

This will execute command1 and pass its output to command2 as input.

Get-Process | Where-Object { $_.WorkingSet -gt 2000000 } | Sort-Object -Property WorkingSet | Format-Table -Property Name, WorkingSet

This example retrieves a list of processes running on the computer, filters out processes with a working set less than 2 MB, sorts the remaining processes by working set size, and then formats the output as a table with the process name and working set size.

Piping is a powerful feature in PowerShell that allows you to perform complex tasks with just a few lines of code. It is an essential part of working with PowerShell and is widely used in scripts and interactive sessions.
