Summary
PowerShell has a very rich set of cmdlets that deal with file input and output. We've seen how to read and write text files, CSV files, and CLIXML files. We, also, looked at how to use redirection to cause PowerShell to write streams to files or combine streams together.
In the next chapter, we will look at one way by which PowerShell can communicate with different kinds of software and components on a computer, using WMI and CIM. These capabilities greatly expand PowerShell's power, and causes it to be an almost universal tool in the Microsoft environment.
