Write-Host $grepString

I used this code but it is printing only one line(when it get \n), But I want my output in containing rest of the lines

Answer 1

You could use the .Where() extension method in SkipUntil mode:

$result = Get-Content -Path D:\out.txt  
$filteredResults = $result.Where({$_ -match "startpoint of the string"}, 'SkipUntil')

$filteredResults is now an list of the input strings from the first match till the end.
