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.

Binary operators


Binary operators are used to perform bit-level operations. Each operator returns the numeric result of the operation:

  • Binary and: -band
  • Binary or: -bor
  • Binary exclusive or: -bxor
  • Binary not: -bnot

Binary and

The result of -band is a number where each of the bits is set in both the value on the left and the value on the right.

In the following example, the result is 2:

11 -band 6 

This operation can be shown in a table:
