Powershell gci中的一个功能。 将带有通配符的文件名变量传递给函数

Question

I was trying to pass parameters to a function to do get-childitem. Seems it cannot be done. Furthermore I can't delete my post so I'm just emptying it out with a basic explanation of what I was trying to figure out. Seems I cannot pass filename variables with wildcards in them. Every answer in here so far does not help me as everything I've tried generates a zero byte file.

Function getFilenames($facPath,$facility,[string[]]$fileIncludes) {

    gci $facPath\* -Include $fileIncludes -Recurse | 
      Select-Object @{ expression={$_.name}; label='FILENAME' },
      @{Name='FACILITY';Expression={$facility}} | 
      Export-Csv -NoTypeInformation -Path $scriptPath"\filenames.txt" -Append

  }

getFilenames $vPath "Building 1" $vFiles

Answer 1

Try this!

$Include=@("ab*","cd*","ef*")
Get-Childitem -Recurse -Include $Include

Answer 2

You can update your function to the following. I removed several Select-Object commands because you only need one.

Function getFilenames($facPath,$facility,[string[]]$fileIncludes) {

    gci $facPath -Include $fileIncludes | 
      Select-Object @{ expression={$_.name}; label='FILENAME' },
      @{Name='FACILITY';Expression={$facility}} | 
      Export-Csv -NoTypeInformation -Path "$scriptPath\filenames.txt" -Append

  }

You can run this like the following:

getFilenames "c:\folder\facilities\*" "manufacturing" "ab*","cd*","ef*"

PowerShell determines a string array by various notations:

• "string1","string2","stringx" : Comma-separated list
• [string[]]$stringArray : Typing or casting
• @("string1","string2","string3") : Array sub-expression
