列出所有与模式匹配的文件名但似乎无法列出我需要的文件我最终会用用户输入替换过滤器
$src = $env:ININ_TRACE_ROOT
$cmp = $env:COMPUTERNAME
$dst = $env:USERPROFILE + "\Desktop\" + $cmp
$lDate = Read-Host "Which Date?"
$s2 = $src + "\$ldate\"
$filter = "ip"
Get-ChildItem -Path $s2 | Where-Object { $_.Name -match $filter } | Select Name
尝试上面的问题是它返回

关于如何实现这一目标的任何想法
使用此更新现在返回列表但是有更好的方法吗？
$filter = "^ip[^server][^db][^ininlog_journal]"
这也有效，但缺少非ip.zip
$filter = "^ip_[0-9]"
答案 0 :(得分：3)
由于-match使用正则表达式，您应该能够编写如下内容：
get-childitem $s2 | where-object { $_.Name -match '^ip' }
（即，当Name属性以ip开头时匹配。）
