We already have an -Index parameter that select the specific indices we provide.
This would be the opposite, allowing us to specify the indices we want to exclude from the output.

PS> 1..5 | Select-Object -SkipIndex  2,3 

1
2
5

A real world example:

Disk Usage (du.exe) outputs a weird line "Processing..." in the middle of the output when asking for CSV output AND the output is redirected.

$a = du -q -nobanner -c .
$a

Path,CurrentFileCount,CurrentFileSize,FileCount,DirectoryCount,DirectorySize,DirectorySizeOnDisk
Processing...

"C:\Users\sgustafsson\vimfiles",2,3427,13,8,31129,94496

This makes conversion from csv an exercise in coding.
With my suggested parameter, it would be as simple as

du -q -nobanner -c . | Select-Object -SkipIndex 1,2 | ConvertFrom-Csv -delimiter ','
