如何从命令行将带括号的参数传递给 Powershell？

Question

I have a Powershell script called MSSQLStartStopServices.ps1 used to stop some SQL Server services. This script is being called using a third-party vendor software. The parameters in question are Fully qualified instance name and Start|Stop

eg

MSSQLStartStopServices.ps1 HOSTNAME\INSTANCENAME Start

For a default instance, the software passes (local) as the INSTANCENAME.

MSSQLStartStopServices.ps1 HOSTNAME\(local) Start

But when I run this I get an error from Powershell:

The term 'local' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

When I try and put the instance name in quotes it works fine in a Powershell window:

MSSQLStartStopServices.ps1 "HOSTNAME\(local)" Start

However the third party software calls Powershell from the commandline first, like so:

powershell .\MSSQLStartStopServices.ps1 "HOSTNAME\(local)" Start

This causes the same error as if the quotes were not there.

How do I work around this issue?

Answer 1

尝试将脚本调用括在双引号中，然后将每个参数括在单引号中：

".\MSSQLStartStopServices.ps1" 'HOSTNAME\(local)' 'Start'

Answer 2

Adding this information for any future people with a smiliar issue finding this page:

In case you want to use a variable as a parameter value that contains characters such as "(" or "|", you need to do it like this: -parameter_name ("'" + $variable + "'")

This worked for me since powershell would remove any double quotes added to the string when calling a non powershell method.
