[PowerShell] 進行日誌記錄

為了令troubleshooting 可以有更多資料, logging 是其中一種手段. 在寫code時, 可以利用log4J 或log4net 去實現. 但在寫Script 時, 則須要自己處理.

因此, 在PowerShell 中, 寫了一個function 去進行logging 如下:

$logFilePath="C:\Temp\log_"+$executeDateFormat+".log"

function Write-Log($content)
{
	Write-Debug $content
    $logDateTime=Get-Date
	Add-Content $logFilePath -value "[$logDateTime] $content"
}

Write-Log "Hello World!!!"

它除了將內容寫到log file外, 還會於PowerShell 的debug mode 中顯示出來, 方便嘗試reproduce 錯誤以作進一步的診斷.

然而, 要留要log path 若會寫入folder內的話, 須要先行設好, 否則會throw exception.
