Why does this powershell snippet produce extra blank lines?

Question

This command will produce 1 extra line at the top and 3 more at the bottom.

Get-Process | select Name  | ft -HideTableHeaders | Out-File .\process.txt

The same thing happens with other lists such as reading a directory.

Answer 1

Same result as in previous answer, but in another syntax:

Get-Process | foreach{ $_.Name}  > .\process.txt

There still is empty line in the end, though

Answer 2

You can turn it into a string and trim it:

(Get-Process | select Name  | ft -HideTableHeaders | Out-String).Trim() | Out-File .\process.txt

Rather than three, there is now only one empty line at the end.
