In Chapter 3, Working with Objects in PowerShell, we started exploring the different output streams PowerShell utilizes.
Information from a command may be redirected using the redirection operator >. Information may be sent to another stream or a file.
For example, the output from a command can be directed to a file. The file will contain the output as it would have been displayed in the console:
PS> Get-Process -Id $pid > process.txt
PS> Get-Content process.txt
Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName
