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 = "\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?

Accepted Answer

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
```
