Hi

I am trying to find away to remove Duplicate words from a text file using Powershell

   
Name1 PC1234 PC1234 start Tue 2/17 6:53
Name2 PC5678 PC5678 start Tue 2/17 7:51

What I would like is


Name1 PC1234 start Tue 2/17 6:53
Name2 PC5678 start Tue 2/17 7:51

I have managed to get it working using the following but I would like to be able to open a .txt file remove the duplicate on all lines and right the content back to a new file.

$text= "Name1 PC1234 PC1234 start Tue 2/17 6:53"
$text.Length
$text.remove(14)

Open in new window


Thank you of your help

Might not be a solution that your looking for, but the easiest way to accomplish this is in Excel and using the remove duplicate button.

So the third column is always a copy of the second?
This will remove the third column:
Get-Content C:\Temp\in.txt | % {$_.Split(" ")[0..1+3..($_.Length -1)] -join " "} | Set-Content C:\Temp\out.txt

Hi oBda

Almost there and I understand the $_.Split

How would I be able to get the code to ignore the 1st line in the text file.


Keep this text
Name1 PC1234 PC1234 start Tue 2/17 6:53
Name2 PC5678 PC5678 start Tue 2/17 7:51

Thank you

$(
Get-Content C:\Temp\in.txt | select -First 1
Get-Content C:\Temp\in.txt | select -Skip 1 | % {$_.Split(" ")[0..1+3..($_.Length -1)] -join " "}
) | Set-Content C:\Temp\out.txt
