Mastering Windows PowerShell Scripting

Chapter 2. Data Parsing and Manipulation

One of the most powerful features of PowerShell is its ability to retrieve and manipulate data. Many a times when you retrieve data from a PowerShell session, the format in which it is available is different from what you would want to display in the PowerShell window or in a log file. For this purpose, PowerShell provides powerful cmdlets and methods to perform data manipulation to best suit your needs as a PowerShell scripter.

While reading this chapter, you'll learn the following concepts:

String manipulation
Number manipulation and parsing
Date/time manipulation
Forcing data types
PowerShell pipeline

Date and time manipulation

When you are scripting, there are times where you may need to get the date and time of a system. PowerShell offers the get-date cmdlet, which provides the date and time in many different formats of your choice.

To obtain the date object, execute the following command:

$time = get-date
$time

The output of this is shown in the following screenshot:

The standard get-date cmdlet, without any triggers, will generate the long date and time format. When you store the date object in a variable, it is important to remember that the data captured from the cmdlet is a snapshot in time. You'll have to call the get-date cmdlet again to get new values for the updated date and time.

The following table displays all of the date time formatting codes:

Format code	Result	Example
MM	Month in numeric format	04
DD	Day in numeric format	15
YYYY	Year in numeric format	2014
HH	Hour in numeric format (24hrs)	14
hh	Hour in numeric format (12hrs)	02
mm	Minutes in numeric...

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

Me May 23, 2015

I have numerous books on PowerShell and have been working with PowerShell for only a few months. But this is the first book on PowerShell that I can say truly speaks to me. The light bulb came on as I was reading this book. It is well written and organized in such a manner that I can honestly see myself taking my PowerShell skills to the next level. It is an absolutely great book that I would highly recommend to anyone who also wants to take their PowerShell skills to the next level. Each chapter made me want to continue reading more and had me looking forward to the next chapter. I am also looking forward to introducing this book to all of my co-workers with the hope that they also will build on their knowledge of PowerShell. This book has earned a permanent place on my bookshelf. Thank you for this book…
