I simply want to pass this filter to gci in a variable, but it doesn't work: 我只是想将此过滤器传递给变量中的gci,但是它不起作用:
PS E:\Uploader> $k="M*,S*"
PS E:\Uploader> gci *.* -include $k | where {!$_.PsIsContainer}
PS E:\Uploader> gci *.* -include @($k) | where {!$_.PsIsContainer}
<<no files returned!>>
If I don't save the filter in a variable, it works fine: 如果我不将过滤器保存在变量中,则可以正常工作:
PS E:\Uploader> gci *.* -include S*,M* | where {!$_.PsIsContainer}
Directory: E:\temp\SurveyLoadingAutomation\Uploader
Mode LastWriteTime Length Name

But I need to pass the filter in a variable in a script. 但是我需要在脚本的变量中传递过滤器。
Any idea? 任何想法?
Try like this: 尝试这样:
$k= @("M*","S*")
the -include
parameter accept [string[]]
(an array of string
type ) -include
参数接受[string[]]
( string
类型的数组)
