Question

我无法让脚本正常工作。我有三个阵列。 extensions数组确实可以正确过滤。但是我带有通配符的数组并没有产生我想要的结果。我做错了什么？

# Read List of Servers from flat file
$data=Get-Content C:\myscripts\admin_servers.txt

# Variables that will be used against search parameter
$extensions = @(".ecc", ".exx", ".ezz", ".vvv")
$wildcards = @("Help_*.txt", "How_*.txt", "Recovery+*")
$exclude = @("help_text.txt", "Lxr*.exx", "help_contents.txt")

# Loop each server one by one and do the following
foreach ($server in $data)
{
    # Search the server E:\ and all subdirectories for the following types of
    # extensions or wildcards.
    Get-ChildItem -path \\$server\e$ -Recurse | Where-Object {
        (($extensions -contains $_.Extension) -or $_.Name -like $wildcards) -and
        $_.Name -notlike $exclude
    }
}

Answer 1

您可以编写自己的函数：

function Like-Any {
    param (
        [String]
        $InputString,

        [String[]]
        $Patterns
    )

    foreach ($pattern in $Patterns) {
        if ($InputString -like $pattern) {
            return $true
        }
    }
    $false
}

然后像这样称呼它：

Get-ChildItem -path \\$server\e$ -Recurse | 
Where-Object { `
    (($extensions -contains $_.Extension) -or (Like-Any $_.Name $wildcards)) `
    -and !(Like-Any $_.Name $exclude)}

Answer 2

如果您使用正则表达式很方便，可以通过-Match比较来完成此操作。将您的$Wildcards =和$Exclude =行替换为：

$wildcards = "Help_.*?\.txt|How_.*?\.txt|Recovery\+.*"
$Exclude = "help_text\.txt|Lxr.*?\.exx|help_contents\.txt"

然后您的Where-Object行：

    Where-Object {(($extensions -contains $_.Extension) -or $_.Name -match $wildcards) -and $_.Name -notmatch $exclude}

那应该为你做。 {{3}}上可用$Wildcard =匹配的说明。

Where-Object和Arrays没有正确过滤
