powershell - 在服务名称带有破折号的地方使用Get-Service

Question

我想使用PS脚本启动和停止特定服务。当我使用以下命令时:

Get-Service "SAS [SASConfig-Lev1] SASMeta - Metadata Server" | Where {$_.status –eq 'Stopped'} | Start-Service

我得到错误:

Get-Service : The specified wildcard character pattern is not valid: SAS [SASConfig-Lev1] SASMeta - Metadata Server

At line:1 char:1

+ Get-Service "SAS [SASConfig-Lev1] SASMeta - Metadata Server" | Where  ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-Service], WildcardPatternException
    + FullyQualifiedErrorId : RuntimeException,Microsoft.PowerShell.Commands.GetServiceCommand

问题不在Where子句中，因为如果删除它，则会出现相同的错误。

Get-Service "SAS [SASConfig-Lev1] SASMeta - Metadata Server" | Start-Service

我已经试过了

Get-Service 'SAS [SASConfig-Lev1] SASMeta - Metadata Server' | Start-Service

还有这个

Get-Service "SAS [SASConfig`-Lev1] SASMeta - Metadata Server" | Start-Service

但得到同样的错误。

关于如何在服务名称中包含破折号并使 Get-Service运行无误的任何建议？

Answer 1

您需要进行一些转义操作才能将方括号放入服务名称值中。开头括号前的两个前导坟墓标记(``)没错。转义命令使Get-Service command解析为，而不是，将第一个参数视为包含通配符。

Get-Service "SAS ``[SASConfig-Lev1] SASMeta - Metadata Server"

我的Powershell控制台示例:

> Get-Service "SAS ``[BIserver-Lev1] Web Infrastructure Platform Data Server" | Format-List


Name                : SAS [BIserver-Lev1] Web Infrastructure Platform Data Server
DisplayName         : SAS [BIserver-Lev1] Web Infrastructure Platform Data Server
Status              : Running
DependentServices   : {}
ServicesDependedOn  : {RPCSS}
CanPauseAndContinue : True
CanShutdown         : True
CanStop             : True
ServiceType         : Win32OwnProcess

Wildcards

PowerShell supports the following wildcard characters:

Wildcard  Description   
*         Match zero or more characters
?         Match one character in that position
[ ]       Match a range of characters i.e. [a-j]
[ ]       Match specific characters   i.e. [adrstz]
