What's new in PowerShell 7.0

  • Artikkeli

PowerShell 7.0 is an open-source, cross-platform (Windows, macOS, and Linux) edition of PowerShell, built to manage heterogeneous environments and hybrid cloud.

In this release, we're introducing a number of new features, including:

  • Pipeline parallelization with ForEach-Object -Parallel
  • New operators:
    • Ternary operator: a ? b : c
    • Pipeline chain operators: || and &&
    • Null conditional operators: ?? and ??=
  • A simplified and dynamic error view and Get-Error cmdlet for easier investigation of errors
  • A compatibility layer that enables users to import modules in an implicit Windows PowerShell session
  • Automatic new version notifications
  • The ability to invoke DSC resources directly from PowerShell 7 (experimental)

To see a full list of features and fixes, see the changelogs.

Where can I install PowerShell?

PowerShell 7 currently supports the following operating systems on x64, including:

  • Windows 8.1, and 10
  • Windows Server 2012, 2012 R2, 2016, and 2019
  • macOS 10.13+
  • Red Hat Enterprise Linux (RHEL) / CentOS 7
  • Fedora 30+
  • Debian 9
  • Ubuntu LTS 16.04+
  • Alpine Linux 3.8+

Additionally, PowerShell 7.0 supports ARM32 and ARM64 flavors of Debian, Ubuntu, and ARM64 Alpine Linux.

Check the installation instructions for your preferred operating system Windows, macOS, or Linux.

While not officially supported, the community has also provided packages for Arch and Kali Linux.

Note

Debian 10 and CentOS 8 currently don't support WinRM remoting. For details on setting up SSH-based remoting, see PowerShell Remoting over SSH.

For more up-to-date information about supported operating systems and support lifecycle, see the PowerShell Support Lifecycle.

Running PowerShell 7

PowerShell 7 installs to a directory separately from Windows PowerShell. This enables you to run PowerShell 7 side-by-side with Windows PowerShell 5.1. For PowerShell 6.x, PowerShell 7 is an in-place upgrade that removes PowerShell 6.x.

  • PowerShell 7 is installed to %programfiles%\PowerShell\7
  • The %programfiles%\PowerShell\7 folder is added to $env:PATH

The PowerShell 7 installer package upgrades previous versions of PowerShell 6.x:

  • PowerShell 6.x on Windows: %programfiles%\PowerShell\6 is replaced by %programfiles%\PowerShell\7
  • Linux: /opt/microsoft/powershell/6 is replaced by /opt/microsoft/powershell/7
  • macOS: /usr/local/microsoft/powershell/6 is replaced by /usr/local/microsoft/powershell/7

Note

In Windows PowerShell, the executable to launch PowerShell is named powershell.exe. In version 6 and above, the executable name is changed to support side-by-side execution. The new executable name to launch PowerShell 7 is pwsh.exe. Preview builds remain in-place as pwsh-preview instead of pwsh under the 7-preview directory.

Improved backwards compatibility with Windows PowerShell

PowerShell 7.0 marks a move a to .NET Core 3.1, enabling significantly more backwards compatibility with existing Windows PowerShell modules. This includes many modules on Windows that require GUI functionality like Out-GridView and Show-Command, as well as many role management modules that ship as part of Windows.

For Windows, a new switch parameter UseWindowsPowerShell is added to Import-Module. This switch creates a proxy module in PowerShell 7 that uses a local Windows PowerShell process to implicitly run any cmdlets contained in that module. For more information on Import-Module.

For more information on which Microsoft modules work with PowerShell 7.0, see the Module Compatibility Table.

Parallel execution added to ForEach-Object

The ForEach-Object cmdlet, which iterates items in a collection, now has built-in parallelism with the new Parallel parameter.

By default, parallel script blocks use the current working directory of the caller that started the parallel tasks.

This example retrieves 50,000 log entries from 5 system logs on a local Windows machine:

$logNames = 'Security','Application','System','Windows PowerShell','Microsoft-Windows-Store/Operational'

$logEntries = $logNames | ForEach-Object -Parallel {
    Get-WinEvent -LogName $_ -MaxEvents 10000
} -ThrottleLimit 5

$logEntries.Count

50000

The Parallel parameter specifies the script block that's run in parallel for each input log name.

The new ThrottleLimit parameter limits the number of script blocks running in parallel at a given time. The default is 5.

Use the $_ variable to represent the current input object in the script block. Use the $using: scope to pass variable references to the running script block.

For more information about ForEach-Object.

Ternary operator

PowerShell 7.0 introduces a ternary operator which behaves like a simplified if-else statement. PowerShell's ternary operator is closely modeled from the C# ternary operator syntax:

<condition> ? <if-true> : <if-false>

The condition-expression is always evaluated and its result converted to a Boolean to determine which branch is evaluated next:

  • The <if-true> expression is executed if the <condition> expression is true
  • The <if-false> expression is executed if the <condition> expression is false

For example:

$message = (Test-Path $path) ? "Path exists" : "Path not found"

In this example, if the path exists, then Path exists is displayed. If the path doesn't exist, then Path not found is displayed.

For more information About If.

Pipeline chain operators

PowerShell 7 implements the && and || operators to conditionally chain pipelines. These operators are known in PowerShell as "pipeline chain operators", and are similar to AND and OR lists in shells like bash and zsh, as well as conditional processing symbols in the Windows Command Shell (cmd.exe).

The && operator executes the right-hand pipeline, if the left-hand pipeline succeeded. Conversely, the || operator executes the right-hand pipeline if the left-hand pipeline failed.

Note

These operators use the $? and $LASTEXITCODE variables to determine if a pipeline failed. This allows you to use them with native commands and not just with cmdlets or functions.

Here, the first command succeeds and the second command is executed:

Write-Output 'First' && Write-Output 'Second'

First
Second

Here, the first command fails, the second isn't executed:

Write-Error 'Bad' && Write-Output 'Second'

Write-Error: Bad

Here, the first command succeeds, the second command isn't executed:

Write-Output 'First' || Write-Output 'Second'

First

Here, the first command fails, so the second command is executed:

Write-Error 'Bad' || Write-Output 'Second'

Write-Error 'Bad'
Second

For more information About Pipeline Chain Operators.

Null-coalescing, assignment, and conditional operators

PowerShell 7 includes Null coalescing operator ??, Null conditional assignment ??=, and Null conditional member access operators ?. and ?[].

Null-coalescing Operator ??

The null-coalescing operator ?? returns the value of its left-hand operand if it'sn't null. Otherwise, it evaluates the right-hand operand and returns its result. The ?? operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null.

$x = $null
$x ?? 100
100

In the following example, the right-hand operand won't be evaluated:

[string] $todaysDate = '1/10/2020'
$todaysDate ?? (Get-Date).ToShortDateString()
1/10/2020

Null conditional assignment operator ??=

The null conditional assignment operator ??= assigns the value of its right-hand operand to its left-hand operand only if the left-hand operand evaluates to null. The ??= operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null.

$x = $null
$x ??= 100
$x
100

In the following example, the right-hand operand isn't evaluated:

[string] $todaysDate = '1/10/2020'
$todaysDate ??= (Get-Date).ToShortDateString()
1/10/2020

Null conditional member access operators ?. and ?[] (Experimental)

Note

This is an experimental feature named PSNullConditionalOperators. For more information, see Using Experimental Features.

A null conditional operator permits member access, ?., or element access, ?[], to its operand only if that operand evaluates to non-null; otherwise, it returns null.

Note

Since PowerShell allows ? to be part of the variable name, formal specification of the variable name is required for using these operators. So it's required to use {} around the variable names like ${a} or when ? is part of the variable name ${a?}.

In the following example, the value of the member property Status is returned:

$Service = Get-Service -Name 'bits'
${Service}?.status
Stopped

The following example returns null, without trying to access the member name Status:

$service = $Null
${Service}?.status

Similarly, using ?[], the value of the element is returned:

$a = 1..10
${a}?[0]
1

And when the operand is null, the element isn't accessed and null is returned:

$a = $null
${a}?[0]

For more information About_Operators.

New view ConciseView and cmdlet Get-Error

PowerShell 7.0 enhances the display of error messages to improve the readability of interactive and script errors with a new default view ConciseView. The views are user-selectable through the preference variable $ErrorView.

With ConciseView, if an error isn't from a script or parser error, then it's a single line error message:

Get-Childitem -Path c:\NotReal

Get-ChildItem: can't find path 'C:\NotReal' because it doesn't exist

If the error occurs during script execution or is a parsing error, PowerShell returns a multiline error message that contains the error, a pointer and error message showing where the error is in that line. If the terminal doesn't support ANSI color escape sequences (VT100), then colors aren't displayed.

Error display from a script

The default view in PowerShell 7 is ConciseView. The previous default view was NormalView and you can select this by setting the preference variable $ErrorView.

$ErrorView = 'NormalView' # Sets the error view to NormalView
$ErrorView = 'ConciseView' # Sets the error view to ConciseView

Note

A new property ErrorAccentColor is added to $Host.PrivateData to support changing the accent color of the error message.

A new cmdlet Get-Error provides a complete detailed view of the fully qualified error when desired. By default the cmdlet displays the full details, including inner exceptions, of the last error that occurred.

Display from Get-Error

The Get-Error cmdlet supports input from the pipeline using the built-in variable $Error. Get-Error displays all piped errors.

$Error | Get-Error

The Get-Error cmdlet supports the Newest parameter, allowing you to specify how many errors from the current session you wish displayed.

Get-Error -Newest 3 # Displays the lst three errors that occurred in the session

For more information about Get-Error.

New version notification

PowerShell 7 uses update notifications to alert users to the existence of updates to PowerShell. Once per day, PowerShell queries an online service to determine if a newer version is available.

Note

The update check happens during the first session in a given 24-hour period. For performance reasons, the update check starts 3 seconds after the session begins. The notification is shown only on the start of subsequent sessions.

By default, PowerShell subscribes to one of two different notification channels depending on its version/branch. Supported, Generally Available (GA) versions of PowerShell only return notifications for updated GA releases. Preview and Release Candidate (RC) releases notify of updates to preview, RC, and GA releases.

The update notification behavior can be changed using the $Env:POWERSHELL_UPDATECHECK environment variable. The following values are supported:

  • Default is the same as not defining $Env:POWERSHELL_UPDATECHECK
    • GA releases notify of updates to GA releases
    • Preview/RC releases notify of updates to GA and preview releases
  • Off turns off the update notification feature
  • LTS only notifies of updates to long-term-servicing (LTS) GA releases

Note

The environment variable $Env:POWERSHELL_UPDATECHECK doesn't exist until it's set for the first time.

To set the version notification for LTS releases only:

$Env:POWERSHELL_UPDATECHECK = 'LTS'

To set the version notification to the Default behavior:

$Env:POWERSHELL_UPDATECHECK = 'Default'

For more information About Update Notifications.

New DSC Resource support with Invoke-DSCResource (Experimental)

Note

This is an experimental feature named PSDesiredStateConfiguration.InvokeDscResource. For more information, see Using Experimental Features.

The Invoke-DscResource cmdlet runs a method of a specified PowerShell Desired State Configuration (DSC) resource.

This cmdlet invokes a DSC resource directly, without creating a configuration document. Using this cmdlet, configuration management products can manage Windows or Linux by using DSC resources. This cmdlet also enables debugging of resources when the DSC engine is running with debugging enabled.

This command invokes the Set method of a resource named WindowsProcess and provides the mandatory Path and Arguments properties to start the specified Windows process.

Invoke-DscResource -Name WindowsProcess -Method Set -ModuleName PSDesiredStateConfiguration -Property @{
  Path = 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe'
  Arguments = ''
}

For more information about Invoke-DSCResource.
