```

Key Citrix PowerShell Cmdlets

Here are some essential cmdlets to manage Citrix environments:

- Managing Sessions:

  - `Get-BrokerSession`: Retrieves active Citrix sessions.

  - `Stop-BrokerSession`: Terminates specific sessions.

- Managing Applications:

  - `New-BrokerApplication`: Creates a new application.

  - `Remove-BrokerApplication`: Deletes an application.

  - `Set-BrokerApplication`: Updates application properties.

- Managing Desktops:

  - `Get-BrokerDesktop`: Retrieves information about desktops.

  - `Restart-BrokerDesktop`: Restarts a virtual desktop.

 - Managing Policies:

  - `Get-Policy`: Lists all Citrix policies.

  - `New-Policy`: Creates a new policy.

  - `Set-Policy`: Modifies an existing policy.

 Practical Examples

Let's explore some common tasks you can automate with PowerShell in a Citrix environment.

1. Fetching Active User Sessions

This script retrieves a list of active Citrix sessions:

 ```powershell

Fetch active sessions

$sessions = Get-BrokerSession

Display session details

$sessions | Select-Object UserName, MachineName, SessionState

```

2. Creating a New Published Application

 Here’s how to create a new application in Citrix:

```powershell

Define application parameters

$appName = "Notepad"

$path = "C:\Windows\System32\notepad.exe"

$deliveryGroup = "DeliveryGroup1"

Create the application

New-BrokerApplication -Name $appName -CommandLineExecutable $path -DeliveryGroup $deliveryGroup

```

3. Restarting Virtual Desktops

 This script restarts all desktops in a specific delivery group:

```powershell

Specify the delivery group

$deliveryGroup = "DeliveryGroup1"

Fetch desktops in the group

$desktops = Get-BrokerDesktop -DeliveryGroupName $deliveryGroup

Restart each desktop

foreach ($desktop in $desktops) {

    Restart-BrokerDesktop -MachineName $desktop.MachineName

}

```

 4. Automating Policy Changes

 Modify an existing policy to enable USB redirection:

 ```powershell

# Fetch the policy

$policy = Get-Policy -Name "USB Policy"

Update the policy

Set-Policy -PolicyName $policy.Name -EnableUSBRedirection $true

```
