Getting last X characters from each line PowerShell

Question

I'm trying to get the last 8 characters of every line of an array in the pipeline, I thought this would output the last 8 characters but the output seems to be blank

foreach($line in $Texfile) 
{
$line[-8..-1]-join ''
}

Answer 1

Try this:

foreach ($Line in $Texfile) {
  $Line.Remove(0, ($Line.Length - 8))
}

Answer 2

There's any number of ways to do this, but I opted to pipe Get-Content to ForEach-Object.

Get-Content -Path <Path\to\file.txt> | ForEach-Object {
    $_.Substring($_.Length - 8)
}

In your example, you'd use $Line in place of $_ and not pipe to ForEach-Object, and instead, use the Foreach language construct as you've done.

Foreach ($Line in $TextFile) {
    $Line.Substring($Line.Length - 8)
}
