I need to find the duplicate values in a text file using power shell let's say if the file content is
Apple
Orange
Banana
Orange
Orange
Desired output should be
Orange
Orange
You can also use the Group-Object cmdlet to see if any lines occur more than once:
e.g.
Get-Content test.txt | Group-Object | Where-Object { $_.Count -gt 1 } | Select -ExpandProperty Name
Used the Commands mentioned below and it worked.
PS C:\Projects> $OriginalContent, $UniqueContent = (Get-Content .\File.txt), (Get-Content .\File.txt | Sort-object -unique)
PS C:\Projects> compare-object $originalcontent $uniquecontent
or to print the text and the count use the following command
PS C:\Projects> Get-Content .\File.txt | group-object
