I have a text file with two values in each line separated by a space. Now I want to know duplicate values in one of the columns. Is it possible to achieve this using Windows powershell.
Given a text file:
Apple Fruit
Banana Fruit
Carrot Vegetable
Desired output is: (I want to find duplicates in second column)
Fruit
You could use the Import-CSV
cmdlet and specify a whitespace delimiter to easy get access of the second column. Then you can group the objects using the second column and select the one with more than 1 entries:
Import-Csv 'path_to_your_text_file' -Delimiter ' ' -Header @('first', 'second') |
Group-Object second |
Where-Object count -gt 1 |
Select-Object -ExpandProperty name
