Syntax

Uninstall-SCXAgent -Agent <IPersistedUnixComputer[]> [-ComputerName <String[]>] [-Credential <PSCredential>]
 [-SshCredential <CredentialSet>] [-Confirm] [-WhatIf] [-SCSession <Connection[]>] [<CommonParameters>]

Description

The Uninstall-SCXAgent cmdlet uninstalls the management agent on the specified UNIX and Linux computers.

The required Agent parameter specifies the targeted managed UNIX or Linux computers to uninstall and requires a UNIX or Linux computer object. For information about retrieving managed UNIX or Linux computers, see the Get-SCXAgent cmdlet. An optional SSHCredential parameter can be specified to identify the privileged credential used for uninstallation of the management agent. If the SSHCredential is not specified, the cmdlet attempts to use the defined privileged Run As account for the agent.

This cmdlet does not return any output.

Examples

Example 1: Uninstall a management agent

PS C:\>$Agent01 = Get-SCXAgent -Name "nx1.contoso.com"
PS C:\> $SSHCredential = Get-SCXSSHCredential -UserName "DavidChew" -Key "C:\keys\key21.ppk" -ElevationType sudo
PS C:\> Uninstall-SCXAgent -SSHCredential $SSHCredential -Agent $Agent01

The first command gets the agent for a managed Linux or UNIX computer named nx1.contoso.com by using the Get-SCXAgent cmdlet. The command stores it in the $Agent01 variable.

The second command creates a privileged credential for a user by using the Get-SCXSSHCredential cmdlet. The command stores the result in the $SSHCredential variable.

The final command uninstalls the management agent in $Agent01 by using a specified SSH credential.

Example 2: Uninstall a management agent with the defined Run As account

PS C:\>Get-SCXAgent -Name "nx1.contoso.com" | Uninstall-SCXAgent

This command gets the agent for a managed Linux or UNIX computer named nx1.contoso.com by using Get-SCXAgent. The command passes the managed computer to the current cmdlet. The command uninstalls the management agent by using the defined Run As account.

Parameters

-Agent

Specifies one or more managed UNIX or Linux computer objects. For information about how to get a managed UNIX or Linux computer object, type Get-Help Get-SCXAgent.

Type:IPersistedUnixComputer[]

Accept wildcard characters:False
-Credential

Specifies the user account under which the management group connection runs. Specify a PSCredential object, such as one that the Get-Credential cmdlet returns, for this parameter. For more information about credential objects, type Get-Help Get-Credential.

If you specify a computer in the ComputerName parameter, use an account that has access to that computer. The default is the current user.

Type:PSCredential
Required:False
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-SshCredential

Specifies a privileged SSH credential used to perform the agent maintenance actions. If this parameter is not specified, the cmdlet attempts to use the defined agent maintenance Run As account for the agent.
