我正在阅读很多帖子 - 但对我个人来说没什么。 我需要以下面的形式拆分文本文件:
--------------------- Instance Type and Transmission --------------
...text..
...text..
--------------------------- Message Trailer ------------------------
...text...
...text...
--------------------- Instance Type and Transmission --------------
...text..
...text..
按行------------- Instance Type and Transmission --------------
划分内容,并在较新的文件中输出文本。
像这样:
File1中:
--------------------- Instance Type and Transmission --------------
...text..
...text..
--------------------------- Message Trailer ------------------------
...text...
...text...
文件2:
--------------------- Instance Type and Transmission --------------
...text..
...text..
Perl和awk这样做非常简单,我发现了一些例子,在PowerShell中没有任何内容,只有文本文件按大小分割。
感谢@CB。我结束时此解决方案对多个文件有效:
$InPC = "C:\Scripts"
Get-ChildItem -Path $InPC -Filter *.txt | ForEach-Object -Process {
$basename= $_.BaseName
$m = ( ( Get-Content $_.FullName | Where { $_ | Select-String "--------------------- Instance Type and Transmission --------------" -Quiet } | Measure-Object | ForEach-Object { $_.Count } ) -ge 2)
$a = 1
if ($m) {
Get-Content $_.FullName | % {
If ($_ -match "--------------------- Instance Type and Transmission --------------") {
$OutputFile = "$InPC\$basename _$a.txt"
$a++
}
Add-Content $OutputFile $_
}
Remove-Item $_.FullName
}
}
答案 0 :(得分:1)
这样的事情应该有效:
$InputFile = "c:\path\myfiletosplit.txt"
$Reader = New-Object System.IO.StreamReader($InputFile)
$a = 1
While (($Line = $Reader.ReadLine()) -ne $null) {
If ($Line -match "--------------------- Instance Type and Transmission --------------") {
$OutputFile = "MySplittedFileNumber$a.txt"
$a++
}
Add-Content $OutputFile $Line
}
或没有.net类:
$a = 1
gc "c:\path\myfiletosplit.txt" | % {
If ($_ -match "--------------------- Instance Type and Transmission --------------") {
$OutputFile = "MySplittedFileNumber$a.txt"
$a++
}
Add-Content $OutputFile $_
}
