Question

I’m new to PowerShell, but I would like to use it, because there isn’t a easy way to get the length of a string in Windows batch.

I need to write a piece of code in PowerShell that go through each line in a .txt file and determine the character length of that line. If the character length is over 250 then….etc.

The ….etc part is not important at the moment 🙂

In Windows batch I would write it like this:

FOR /F %%A IN ("C:\TestFile.txt") DO (
    SET LINE=%%A
    If LINE > 250 characters then (        ' This line is made up
    ....etc
    )

How can I do it?

Answer 1

The following will do what you want:

$data = Get-Content "C:\TestFile.txt"
foreach($line in $data)
{
   if ($line.Length -gt 250) {
       Write-Host "A match"
   }
}
