The latest version, PowerShell 7.2.1, brings a wealth of new features and enhancements that make it easier to automate tasks, manage systems, and perform complex operations.
In this article, we'll cover everything you need to know about downloading and installing PowerShell 7.2.1, including code examples that demonstrate some of its key features and capabilities.
Downloading PowerShell 7.2.1
PowerShell 7.2.1 can be downloaded from the official Microsoft website. The installation package is available for Windows, macOS, and Linux.
To download PowerShell 7.2.1 on Windows, go to the official Microsoft website and click the "Download" button. This will download the installation package to your computer. Once the download is complete, double-click the package to start the installation process.
To download PowerShell 7.2.1 on macOS, you will need to use the Homebrew package manager. To do this, open a terminal window and run the following command:

To download PowerShell 7.2.1 on Linux, you will need to use a package manager for your specific distribution. For example, on Ubuntu, you can run the following command to install PowerShell 7.2.1:
sudo apt-get install powershell
Once you have installed PowerShell 7.2.1, you can launch it by opening a terminal window and typing pwsh.
Code Examples
Now that we've covered how to download and install PowerShell 7.2.1, let's take a look at some code examples that demonstrate some of its key features and capabilities.
Working with Objects
One of the most powerful features of PowerShell 7.2.1 is its ability to work with objects. Objects are a type of data structure that allow you to represent information in a more structured way. For example, you can use objects to represent files, directories, and other resources on your system.
Here's a code example that demonstrates how to work with objects in PowerShell 7.2.1:
# Create a new object
$obj = [PSCustomObject]@{
Name = "John Doe"
Age = 35
Occupation = "IT Professional"
}
# Access object properties
Write-Output $obj.Name
Write-Output $obj.Age
Write-Output $obj.Occupation
# Modify object properties
$obj.Age = 36
Write-Output $obj.Age
In this example, we create a new object $obj and assign it several properties, such as Name, Age, and Occupation. We then access these properties using the dot notation (.) and modify the value of the Age property.
Working with Files and Directories
Another common use case for PowerShell 7.2.1 is working with files and directories. This can be done using the Get-ChildItem cmdlet, which allows you to list the contents of a directory.
Here's a code example that demonstrates how to work with files and directories in PowerShell 7.2.1:
# List the contents of a directory
Get-ChildItem -Path C:\Windows
# Get information about a specific file
Get-ChildItem -Path C:\Windows\System32\notepad.exe | Select-Object Name, Length, LastWriteTime
# Create a new directory
New
Working with Strings and Text Processing
One of the strengths of PowerShell 7.2.1 is its ability to process text and manipulate strings. This is especially useful for tasks such as parsing log files, processing text-based data, and transforming strings into a desired format.
Here's a code example that demonstrates how to work with strings and perform text processing in PowerShell 7.2.1:
Define a string variable
$str = "Hello, World!"
Convert the string to uppercase
Write-Output $str.ToUpper()
Replace text within a string
Write-Output $str.Replace("Hello", "Goodbye")
Split a string into an array of strings
$words = $str.Split(" ")
Write-Output $words
Join an array of strings into a single string
$newStr = $words -join "-"
Write-Output $newStr
In this example, we define a string variable `$str`, convert it to uppercase, replace text within the string, split the string into an array of words, and join the array back into a single string.
Working with Remote Systems
Another important aspect of PowerShell 7.2.1 is its ability to manage remote systems. This can be done using the `Invoke-Command` cmdlet, which allows you to run commands on remote systems using the Windows Remote Management (WinRM) protocol.
Here's a code example that demonstrates how to manage remote systems in PowerShell 7.2.1:
Define a remote computer
$computerName = "RemoteComputer"
Run a command on the remote computer
Invoke-Command -ComputerName $computerName -ScriptBlock { Get-Process }
Run a command on multiple remote computers
$computerNames = "RemoteComputer1", "RemoteComputer2", "RemoteComputer3"
Invoke-Command -ComputerName $computerNames -ScriptBlock { Get-Process }
In this example, we define a remote computer `$computerName` and run a command on it using the `Invoke-Command` cmdlet. We also demonstrate how to run a command on multiple remote computers by specifying an array of computer names.
