问题
i'm reading a lot of threads - but nothing for me personal. I need to split text file in the following form:
--------------------- Instance Type and Transmission --------------
...text..
...text..
--------------------------- Message Trailer ------------------------
...text...
...text...
--------------------- Instance Type and Transmission --------------
...text..
...text..
dividing content by lines ------------- Instance Type and Transmission --------------
and output text between in newer file.
Like this:
File1:
--------------------- Instance Type and Transmission --------------
...text..
...text..
--------------------------- Message Trailer ------------------------
...text...
...text...
File2:
--------------------- Instance Type and Transmission --------------
...text..
...text..
Perl and awk do this pretty simple and i found some examples, and nothing in powershell, only text file by size splitting.
Thanks to @CB. I ended with this solution valid for multiple files:
$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
}
}

Something like this should work:
$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
}
or whitout .net class:
$a = 1
gc "c:\path\myfiletosplit.txt" | % {
If ($_ -match "--------------------- Instance Type and Transmission --------------") {
$OutputFile = "MySplittedFileNumber$a.txt"
$a++
}
Add-Content $OutputFile $_
}
