Powershell export output variable to file not found - powershell

Question

I have the following script and as much as I try to send the output result, it does not go to the file and therefore the txt file is empty, if you can tell me where I am failing I would appreciate it.
Clear-Content .\telnet.txt
Write-host "Prueba de conexión de puertos"
'-'*30
' '*25
$test = #('WEB:google.com:443','WEBSERVER_HTTP:www.noticias3d.com:80')
Foreach ($t in $test)
{
$description = $t.Split(':')[0]
$source = $t.Split(':')[1]
$port = $t.Split(':')[2]
Write-Host "Conectando a $description host $source puerto $port"
try
{
$socket = New-Object System.Net.Sockets.TcpClient($source, $port)
$_.Message
}
catch [Exception]
{
Write-Host $_.Exception.GetType().FullName
Write-Host $_.Exception.Message
}
Out-File -FilePath telnet.txt
Write-Host "Revisado`n"
}
#$wsh = New-Object -ComObject Wscript.Shell
#$wsh.Popup("Finalizado checklist de Plataforma")

Answer 1

As per the out-file help:
The Out-File cmdlet sends output to a file
In your example you haven't provided any output so you are just getting an empty file. Try
"my file content" | Out-File -FilePath telnet.txt
or just use the redirection operator:
"my file content" > telnet.txt

Answer 2

You are not giving anything to Out-File to send. A foreach(...) statement does not produce pipeline output. Even if it did, you aren't actually chaining them together. Assign the output of the foreach loop to a variable, then pipe that variable to Out-File. I'd actually recommend you use Set-Content instead.
Clear-Content .\telnet.txt
Write-host "Prueba de conexión de puertos"
'-'*30
' '*25
$test = #('WEB:google.com:443','WEBSERVER_HTTP:www.noticias3d.com:80')
$result = Foreach ($t in $test)
{
$description = $t.Split(':')[0]
$source = $t.Split(':')[1]
$port = $t.Split(':')[2]
Write-Host "Conectando a $description host $source puerto $port"
try
{
$socket = New-Object System.Net.Sockets.TcpClient($source, $port)
$_.Message
}
catch [Exception]
{
Write-Host $_.Exception.GetType().FullName
Write-Host $_.Exception.Message
}
$result | Set-Content -FilePath telnet.txt
Write-Host "Revisado`n"
}
As an alternative you could use the pipeline instead.
Clear-Content .\telnet.txt
Write-host "Prueba de conexión de puertos"
'-'*30
' '*25
$test = #('WEB:google.com:443','WEBSERVER_HTTP:www.noticias3d.com:80')
$test | ForEach-Object {
$description = $_.Split(':')[0]
$source = $_.Split(':')[1]
$port = $_.Split(':')[2]
Write-Host "Conectando a $description host $source puerto $port"
try
{
$socket = New-Object System.Net.Sockets.TcpClient($source, $port)
$_.Message
}
catch [Exception]
{
Write-Host $_.Exception.GetType().FullName
Write-Host $_.Exception.Message
}
} | Set-Content -FilePath telnet.txt
Write-Host "Revisado`n"
You also reference automatic variable $_ in the line $_.Message which is referencing nothing.
