Notes From the Field: A PowerShell Primer
Notes From the Field: A PowerShell Primer
About the Book
Learning PowerShell has become an important skillset for those that manage Microsoft products on-premises or in Office 365. This book was written to provide those new to PowerShell some help in learning PowerShell, not from a theory side of things, but focused on practical, real world advice. As such, the book, while not intended to be an advanced book, does cover some advanced topics and concepts. All code was either written for a real work scenario or used to solve a real world problem. A quick sample of topics in the book should give you, the reader, an idea of what is contained in the book:
- Add and Replace
- Arrays - A Deeper Dive
- Connectivity Testing
- Data Types
- Empty Spaces
- Error Action
- Formatting the Shell?
- Get-Date
- Get-History
- Hash Tables - A Deeper Dive
- Managing Output Files
- Out-GridView
- PowerShell StopWatch
- Read-Host
- Role Based Access Controls (RBAC)
- Sort-Object and Unique Values
- Trim()
That is a small sampling of what is covered.
