Question

The below script works fine and displays all the iformation I need – however, there is a problem in displaying NETSH commands. So, normally in powershell if you enter the below:

netsh int tcp show global

It displays in the TABLe format as below:

TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State          : disabled
Chimney Offload State               : disabled
NetDMA State                        : enabled
Direct Cache Acess (DCA)            : disabled
Receive Window Auto-Tuning Level    : disabled
Add-On Congestion Control Provider  : none
ECN Capability                      : disabled
RFC 1323 Timestamps                 : disabled

However, when I do this in a powershell script that logs to a LOG file the output is all scewed – ie the below:

Querying active state...  TCP Global Parameters ---------------------------------------------- Receive-Side Scaling State          : disabled  Chimney Offload State               : disabled  NetDMA State                        : disabled  Direct Cache Acess (DCA)            : disabled  Receive Window Auto-Tuning Level    : disabled  Add-On Congestion Control Provider  : none  ECN Capability                      : disabled  RFC 1323 Timestamps                 : disabled  

Any idea how I can keep the TABLE format that powershell command prompt displays?

Script:

 $computerdel = gc env:computername

 $t = "D:\temp\$(gc env:computername).log"
 #$e = Test-Path $t rm $t -ErrorAction SilentlyContinue

 #if ( $e -eq $true ) { rm $t }
 #else { Write-Host "Shortcut does not exist." }


 $Logfile = "D:\temp\$(gc env:computername).log"

 Function LogWrite {    Param ([string]$logstring)

    Add-content $Logfile -value $logstring }

 LogWrite

Answer 1

That’s because you LogWrite function simply converts its input to a string and “dumps” it to the log file. The simplest solution for you would be to replace it with appending | Out-File -Append <logfile> to each post you want to put in the log:

>"Some message" | Out-File -Append <logfile>
>netsh int tcp show global | Select-Object -skip 2 | Out-File -Append <logfile>

will produce:

Some message
TCP Global Parameters
---------------------------------------------- 
Receive-Side Scaling State          : enabled
Chimney Offload State               : automatic
NetDMA State                        : enabled
Direct Cache Acess (DCA)            : disabled
Receive Window Auto-Tuning Level    : normal
Add-On Congestion Control Provider  : none
ECN Capability                      : disabled
RFC 1323 Timestamps                 : disabled

(The Select-Object is a simple way to skip some beginning lines from output)
