протоколирование вывода команды netsh в powershell

Question

Сценарий, приведенный ниже, работает нормально и отображает всю необходимую информацию, однако при отображении команд NETSH возникает проблема.Так, обычно в powershell, если вы вводите следующее:

netsh int tcp show global

Отображается в формате TABLe, как показано ниже:

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

Однако, когда я делаю это в скрипте powershell, который регистрируетв файл LOG выводятся все данные, т.е. ниже:

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  

Есть идеи, как сохранить формат TABLE, отображаемый в командной строке powershell?

Сценарий:

 $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

Это потому, что ваша функция LogWrite просто преобразует свои входные данные в строку и «сбрасывает» ее в файл журнала. Самым простым решением для вас будет заменить его добавлением | Out-File -Append <logfile> к каждому сообщению, которое вы хотите поместить в журнал:

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

даст:

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

(Select-Object - простой способ пропустить некоторые начальные строки из вывода)

Answer 2

Строки «верхнего / нижнего колонтитула» можно пропустить с помощью простого регулярного выражения, которое получает строки, соответствующие символу двоеточия:

netsh int tcp show global | where {$_ -match ':'}
