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

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 = "\\server\share\file.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?

Solution

  • After some trial and error, I found that

    $computername = $env:computername

    works to get a computer name, but sending $computername to a file via Add-Content doesn't work.

    I also tried $computername.Value.

    Instead, if I use

    $computername = get-content env:computername

    I can send it to a text file using

    $computername | Out-File $file
