Windows PowerShell to find duplicate lines in a file
powershell, powershell-2.0
Solution
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
Problem
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 ```
