powershell - Output ("echo") a variable to a text file

Question

I'm running a PowerShell script against many servers, and it is logging output to a text file.

I'd like to capture the server the script is currently running on. So far I have:

$file = "\serversharefile.txt"
$computername = $env:computername

$computername | Add-Content -Path $file

This last line adds question marks in the output file. Oops.

How do I output a variable to a text file in PowerShell?

Answer 1

The simplest Hello World example...

$hello = "Hello World"
$hello | Out-File c:debug.txt
