I have a text file as follows
Apple=1
Manggo=1
Appleandmanggobellongsto=Jimmy
Apple=1
Manggo=1
Appleandmanggobellongsto=Dave
Apple=1
Manggo=1
Appleandmanggobellongsto=Carlton
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
get-content $File | select-object -skiplast 3 | set-contect $File
but I dont get anything.
please tell me what I did wrong?
>Solution :
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
