By: Brenton J.W. Blawat

Overview of this book

PowerShell scripts offer a handy way to automate various chores. Working with these scripts effectively can be a difficult task. This comprehensive guide starts from scratch and covers advanced-level topics to make you a PowerShell expert. The first module, PowerShell Fundamentals, begins with new features, installing PowerShell on Linux, working with parameters and objects, and also how you can work with .NET classes from within PowerShell. In the next module, you’ll see how to efficiently manage large amounts of data and interact with other services using PowerShell. You’ll be able to make the most of PowerShell’s powerful automation feature, where you will have different methods to parse and manipulate data, regular expressions, and WMI. After automation, you will enter the Extending PowerShell module, which covers topics such as asynchronous processing and, creating modules. The final step is to secure your PowerShell, so you will land in the last module, Securing and Debugging PowerShell, which covers PowerShell execution policies, error handling techniques, and testing. By the end of the book, you will be an expert in using the PowerShell language.

Item properties


The Get-ItemProperty and Set-ItemProperty commands allow individual properties to be modified.

Filesystem properties

When working with the filesystem provider, Get-ItemProperty and Set-ItemProperty are rarely needed. For example, Set-ItemProperty might be used to make a file read-only. The following example assumes that the somefile.txt file already exists:

                              -                                  

The same property may be directly set from a file object retrieved using Get-Item (or Get-ChildItem):

(Get-Item 'somefile.txt').IsReadOnly = $true

The IsReadOnly flag affects the attributes of the file object, adding the ReadOnly flag.

Adding and removing file attributes

The attributes property of a file object is a bit field presented as a number and given an easily understandable value by the System.IO.FileAttributes enumeration.

Note

Bit fields:A bit-field is a means of exposing multiple settings that have two states (on or off binary states) using a single number...
