多重比较操作员输出错误结果powershell

Question

这是我的脚本：

#set the root search path
$rootPath = "c:testpath"
#get a list of all directories and subdirectories in the root path
$shares = Get-ChildItem -Path $rootPath -Directory
#create empty array to store custom properties later
$obj = @()
#for every folder you find.....
foreach ($share in $shares) {
    #finds all security principals for each share on fileserver that has permissions explicitly assigned   
    $notInherited = Get-Acl -Path $share.FullName |  select -ExpandProperty Access | Where-Object {$_.IsInherited -eq $false} 
    #for every security principal that has explicit permissions assigned....
    foreach ($member in $notInherited) {
        #extract the identity of the resource from the IdentityReference field and convert it to a string object
        [string]$identity = $member.IdentityReference
        #test to see if the extracted resource contains a  anywhere in the name to ensure we're looking for domain objects
        if ($identity -like '**') {
        #retrieve the SAM of the resource by splitting the string object at the  and returning the 1 field
        $samAccountName = $identity.Split('')[1]
            #filter out all domain related groups like domain admins, domain users, domain controllers, domain computers
            if ($samAccountName -notlike 'Domain*' -or $samAccountName -notlike 'Administrators') {
                #return AD object info for the resource using it's SAM
                $ADObject = Get-ADObject -Filter ('SamAccountName -eq "{0}"' -f $SamAccountName)
                #test to ensure we're only retrieving groups and not users who are explicitly assigned
                if ($ADObject.ObjectClass -eq 'group') {
                    #create a PS object and append it's properties to the empty array created earlier
                    #assign custom fields to the object (FolderName maps to the share name and GroupName maps to name of group that has access to the share)
                    $obj += [pscustomobject] @{
                    'GroupName' = $ADObject.Name
                    'FolderName' = $share.Name
                    }   
                }
            }
        }
    }
}
#output the contents of the object to the console
Write-Output $obj | ft -AutoSize | out-file C:Scriptstest02.txt

我想知道为什么这条线会产生错误的结果：

if ($samAccountName -notlike 'Domain*' -or $samAccountName -notlike 'Administrators')

我希望输出不包括任何以"域名"或任何以"域"开头的文件夹。如果我删除第二半以进行测试，以便仅检查"域*"，则输出是正确的。我也需要过滤掉管理员组。我想念什么？

Answer 1

您的请求：

if ($samAccountName -notlike 'Domain*' -or $samAccountName notlike 'Administrators')

从字面上翻译为"不喜欢x"或"不喜欢y"

我认为您正在寻找的是：

if (!($samAccountName -like 'Domain*' -or $samAccountName -like 'Administrators'))

{写入主持人"是"}

这样，如果$ samaccountname就像'domain*'-or $ samaccountName``````````'''''''''，则返回true，然后返回！将其转换为false。

因此，如果满足两种条件，则结果是错误的，并且代码块不运行。因此，如果用户是域*或用户是管理员，则不会输出"是"。
