在选择字符串中指定多个模式

Question

我无法正确格式化选择字符串，以便可以使用多种模式。 我还试图以我的模式来隐藏\\。 其使用目录路径。

这些是我需要搜索的模式：

Successfully FTPed file [\\BATCH1\TO\DENIAL.TXT 

Successfully FTPed file [\\BATCH1\TO\NEWORIGIN.TXT    

Successfully FTPed file [\\BATCH1\TO\ORIGIN.TXT    

Successfully FTPed file [\\BATCH1\TO\Ed.TXT

此代码仅适用于单个模式搜索。

Get-ChildItem -Filter FTP_Outbound*.* -Path $rootFolder| Where-Object {$_.LastWriteTime -gt (get-date).AddDays(-.5)}| Select-String -pattern  ([regex]::Escape('Successfully FTPed file [\\BATCH1\CFGP\TO\DENIAL.TXT'))| % {
  Copy-Item -Path $_.Path -Destination 'c:\Temp' 
}

最后，我希望将文件复制到C：\\ Temp，并在powershell窗口中显示在文件中找到的行。

样本数据：

Answer 1

假设您只希望与这4个路径\\文件名匹配的4行， Successfully FTPed file在该行中具有Successfully FTPed file ，这似乎可行。 [ 咧嘴 ]

Answer 2

我建议您通过RegEx比赛来做到这一点。

例如：使用RegEx进行基于简单模式匹配的多个匹配

Clear-Host

$MyString = @'
[11:18:24 PM] Begin SFTP File \\BATCH1\TO\BRRef[20190724202940].txt To BRRef.txt
[11:18:44 PM] Successfully FTPed file [\\BATCH1\TO\DENIAL.TXT[20190724194428]] to [\DENIAL.TXT]
[11:18:44 PM] Successfully FTPed file [\\BATCH1\TO\NEWORIGIN.TXT[20190724194428]] to [\NEWORIGIN.TXT]
[11:18:44 PM] Successfully FTPed file [\\BATCH1\TO\ORIGIN.TXT[20190724194428]] to [\ORIGIN.TXT]

'@ 

$MyRegExMatch = 'Successfully FTPed.*?TXT'
([regex]::Matches($MyString,$MyRegExMatch).Value)

Clear-Host

Get-Content -Path 'variable:\MyString' | 
ForEach {([regex]::Matches($MyString,$MyRegExMatch).Value)}
