Powershell output to a text file - powershell

Question

I am creating a script that pulls all of the date and time information from our servers. The script gets the servers from a text file. I am having is getting the output of a script to be written to a text file.
I tried using a pipe with Out-File like so:
$servers = gc "C:\Users\Public\Shell_NTP\TestList.txt"
foreach ($server in $servers){
$dt = gwmi win32_operatingsystem -computer $server
$dt_str = $dt.converttodatetime($dt.localdatetime)
write-host "$($server) current local time is $($dt_str)" | Out-File
"C:\Users\Public\Shell_NTP\TestListOutput.txt"
Then I tried the simple carrot output like so:
$servers = gc "C:\Users\Public\Shell_NTP\TestList.txt"
foreach ($server in $servers){
$dt = gwmi win32_operatingsystem -computer $server
$dt_str = $dt.converttodatetime($dt.localdatetime)
write-host "$($server) current local time is $($dt_str)" >
C:\Users\Public\Shell_NTP\TestListOutput.txt
And that did not work either. So any help or advice would be excellent.
TL;DR Trying to get the powershell output into a text file or some other more usable file format.

Answer 1

Don't use write-host - use write-output
write-host will only output your string to the console, the data will not be passed along the pipleline.

Answer 2

You don't need to use write-output you can just
"text" | Out-File ...
into a text file or some other more usable file format
CSV is a more usable format. The format you're writing is something you will have to process again to get the data back out of the text. CSV you can just Import-Csv to get it back. Or open in Excel, etc.
gc "C:\Users\Public\Shell_NTP\TestList.txt" | ForEach {
$dt = gwmi win32_operatingsystem -Computer $_
[PSCustomObject]#{
'ServerName' = $_
'DateTime' = $dt.converttodatetime($dt.localdatetime)
}
} | Export-Csv C:\Users\Public\Shell_NTP\TestListOutput.csv -NoTypeInformation
