Apple=1

Manggo=1

Appleandmanggobellongsto=Dave

Apple=1

I want to remove the last 3 lines and this is what I want to achieve:

Apple=1

Manggo=1

Appleandmanggobellongsto=Jimmy

Apple=1

Manggo=1

Appleandmanggobellongsto=Dave

$File = c:\Text.txt

Set-Contect is not a built-in cmdlet, assuming you meant Set-Content then the issue is that you're trying to read and write to the same file in a single pipeline which results in a blank file. You need to consume the output from Get-Content first and then write to the file, for that you can use the grouping operator ( )

$File = 'c:\Text.txt'
(Get-Content $File) | Select-Object -SkipLast 3 | Set-Content $File
