Как использовать команду tree в powershell для показания файлов и каталогов

PowerShell provides several cmdlets for displaying text on the console screen. As you may have guessed, each cmdlet is intended for a specific purpose. In this article, I will introduce four of these cmdlets and demonstrate how to use them.

The first cmdlet is Write-Warning, which is useful when you need to display a warning message to whoever is running the script.

Write-Warning “This is an example warning.”

Console Output 1

You can display custom warning messages by using the Write-Warning cmdlet.

Write-Warning “This is an example warning.” -WarningAction Inquire

Console Output 2

I am trying to get full structure of my project in tree format in powershell.
When I use the command tree, it only shows directories and subdirectories, but neither files nor hidden folders, such as .git

How can I show files as well?

Similar to generating custom warning messages, you can also create custom error messages. The cmdlet used for doing so is . Additionally, there’s a separate cmdlet called that allows you to generate an error.

You can use the Write-Error cmdlet to display a custom error message.

Write-Error “This is an example error.” -Category InvalidOperation

You can see an example of how an error category works in Figure 4. Microsoft provides a list of all the available categories

Console Output 4

You can append a category to an error message.

cmdlet is similar to the Write-Host cmdlet, but with two notable differences.

Firstly, Write-Output exclusively supports plain text. You can’t change the text color or add other effects to the text.

The second difference is the automatic enumeration of objects by the Write-Object cmdlet. However, if you want to treat an array as a single object within pipeline operations, you can use the

Granted, this is a bit of a nonsense example, but it illustrates the idea that the output is treated as an object.

Such an operation would not be allowed with the Write-Host cmdlet.

Admittedly, I can’t seem to recall ever having used the Write-Output cmdlet in a script. While I am sure that the cmdlet has its place, I can’t think of anything that Write-Output can do that can’t be done using Write-Host and variables.

he NoEnumerate switch allows a collection to be treated as a single item.

cmdlet is the standard command used to display text on the console screen in PowerShell. To use this cmdlet, you simply append the text you want to display. For example:

Write-Host “This text will be displayed on the screen.”

Unlike the Write-Output cmdlet, the Write-Host cmdlet allows you to change both the foreground and the background color of the text. Here’s an example:

Write-Host “White text on a blue background” -Foregroundcolor White -BackgroundColor Blue

Console Output 6

The Write-Host cmdlet supports colorful output.

Unfortunately, Write-Host does not support other text effects such as bold or blinking text. While it was once possible to achieve such effects by embedding various ANSI escape sequences, Microsoft appears to have disabled support for ANSI-based text effects within the PowerShell console. Some ANSI escape sequences, like those for creating a new line or inserting a tab, still work, but those related to text color and attributes (bold, underline, etc.) no longer function.

Different versions of PowerShell have different features and capabilities. So, it is good to know the versions of PowerShell you are using. In this tutorial, I will show you how to check PowerShell version using different methods.

To check your PowerShell version, open PowerShell and type $PSVersionTable.PSVersion to see the version details. Alternatively, you can use Get-Host by typing Get-Host and looking for the Version property, or use Get-Command with (Get-Command powershell).Version. On Windows, you can also check the version in the Registry Editor under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine. For PowerShell Core on Linux or macOS, type pwsh –version in the terminal.

Get the PowerShell version using different methods

Method 1: Using $PSVersionTable

The easiest ways to check your PowerShell version is by using the $PSVersionTable automatic variable. This variable contains a lot of useful information about your PowerShell environment, including the version.

Here is the command.

$PSVersionTable.PSVersion

You can see the screenshot below. I executed the above command using VS code. It shows me the PowerShell version.

Method 2: Using Get-Host

The Get-Host cmdlet provides information about the current host program, including the version of PowerShell.

Get-Host

The output is shown in the screenshot below. It provides a lot of information, including the PowerShell version. This time, I executed the script using Windows PowerShell ISE.

Name             : Windows PowerShell ISE Host
Version          : 5.1.22621.2506
InstanceId       : aaa160fc-9465-4e39-84aa-2737f3b88c08
UI               : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture   : en-IN
CurrentUICulture : en-US
PrivateData      : Microsoft.PowerShell.Host.ISE.ISEOptions
DebuggerEnabled  : True
IsRunspacePushed : False
Runspace         : System.Management.Automation.Runspaces.LocalRunspace

Here the Version property indicates the PowerShell version.

Method 3: Using Get-Command

You can also use the PowerShell Get-Command cmdlets to get the PowerShell version. Below is the complete command.

(Get-Command powershell).Version

Method 4: Checking the Registry (Windows Only)

If you have knowledge about the Windows Registry, you can also check the PowerShell version there.

:/>  Cmd извлечь диск и Можно ли создать файл .bat для быстрого извлечения флешки?

Here are the steps:

1. Press Win + R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to the following path:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine
3. Look for the PowerShellVersion entry, which will display the version.

Method 5: Using PowerShell Core on Linux or macOS

If you are using PowerShell Core on Linux or macOS, you can check the version using the pwsh command.

Here are the steps:

1. Open Terminal.
2. Type the following command and press Enter:pwsh --version
3. The terminal will display the PowerShell version:PowerShell 7.4.0

Conclusion

In this tutorial, I have explained different methods to get the PowerShell version:

• Using $PSVersionTable
• Using Get-Host
• Using Get-Command
• Checking the Registry (Windows Only)
• Using PowerShell Core on Linux or macOS

If you run the same commands every time you launch the PowerShell console, then it’s probably time to customize your PowerShell profile for a smoother scripting experience.

When you develop a profile in PowerShell, you define your settings as a PowerShell script to make the process easier. In this article, learn about the PowerShell profile, how to edit your profile for any PowerShell console — the newer cross-platform PowerShell 7, Windows PowerShell 5.1, Visual Studio (VS) Code and PowerShell Integrated Script Environment (ISE) — and several handy additions for your profile.

How to access your PowerShell profile

The easiest way to retrieve the PowerShell profile is through PowerShell itself. You don’t need to remember the profile paths because they are stored in the variable.

$Profile | Get-Member -MemberType NoteProperty

$Profile.AllUsersAllHosts

$Profile.CurrentUserCurrentHost

code $Profile.CurrentUserCurrentHost

Function Prompt {
    $endChar = '>'
    # check if running as admin
    If
(([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
        $endChar = '#'
    }
    @"
$PWD
PS$endChar
"@
}

    'GivenName',
    'Id',

    'Surname',
    'UserPrincipalName'
)

Get-MgUser -UserId <upn> -Select ($graphUserProps + 'AccountEnabled','UsageLocation')
