I am trying to figure out how to eliminate line breaks when using add-content
echo $server "Uptime: " $uptime.days ", Days" $uptime.hours ", Hours" $uptime.minutes ", Minutes" | add-content $output_file
Basically I have been trying to get the uptime of a server to go to a text file, and when I do this the output comes out
HOSTNAME
Uptime:
, 2 Days
2
, Hours
15
, Minutes
I looked at this question: Powershell replace lose line breaks
Also I went from using out-file -append to add-content, however both produce similar results, can someone shed to some light on how I can eliminate the breaks?

I guess you want to have one line with the info, then:
"$server Uptime: $($uptime.days) Days, $($uptime.hours) Hours, $($uptime.minutes) Minutes" | add-content $output_file
If every item should be on separate line, you might add `n
"$server Uptime`n$($uptime.days) Days`n$($uptime.hours) Hours`n$($uptime.minutes) Minutes" | add-content $output_file
Other possibility is to use -f which is sometimes more readable:
"$server Uptime: {0} Days, {1} Hours, {2} Minutes" -f $uptime.days, $uptime.hours, $uptime.minutes | add-content $output_file
Update
echo is alias for Write-Output (Get-Alias -name echo) which in your case produces array of objects. This array is passed to Add-Content; each object is stored on its own line.

The simplest way to sidestep any problem PowerShell might be putting into the line breaks would be to avoid using the providers.
By using [IO.File]::WriteAllText to write the file, you should be able to avoid the linebreaks that come from PowerShell. The only caveat is that [IO.File]::WriteAllText doesn't understand PowerShell paths, so you'll need to pass it an absolute path.
Hope this helps,

how about
[IO.File]::AppendAllText($testfile,"abc",[System.Text.Encoding]::UTF8)
