我試圖寫一個簡短的runas-admin函數,我可以傳遞另一個函數名稱作爲參數,並使用管理員權限執行該命令(或多或少地等同於Linux中的sudo)。當我嘗試運行這個函數時,它會持續運行,永遠不會結束,佔用大量的CPU。我是PowerShell的新手,那麼我的代碼有什麼問題嗎?如何在當前shell中使用管理權限在PowerShell中運行命令?
function runas-admin
{
# Get the ID and security principal of the current user account
$myWindowsID=[System.Security.Principal.WindowsIdentity]::GetCurrent()
$myWindowsPrincipal=new-object System.Security.Principal.WindowsPrincipal($myWindowsID)
# Get the security principal for the Administrator role
$adminRole=[System.Security.Principal.WindowsBuiltInRole]::Administrator
# Check to see if we are currently running "as Administrator"
if ($myWindowsPrincipal.IsInRole($adminRole))
{
# We are running "as Administrator" - so change the title and background color to indicate this
$Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)"
$Host.UI.RawUI.BackgroundColor = "DarkBlue"
clear-host
}
else
{
# We are not running "as Administrator" - so relaunch as administrator
# Create a new process object that starts PowerShell
$newProcess = new-object System.Diagnostics.ProcessStartInfo "PowerShell";
$newProcess.RedirectStandardError = $TRUE;
$newProcess.RedirectStandardOutput = $TRUE;
$newProcess.UseShellExecute = $FALSE;
# Specify the current script path and name as a parameter
$newProcess.Arguments = $myInvocation.MyCommand.Definition;
# Indicate that the process should be elevated
$newProcess.Verb = "runas";
# Start the new process
$childProcess = [System.Diagnostics.Process]::Start($newProcess);
$childProcess.WaitForExit();
Write-Output $childProcess.StandardOutput.ReadToEnd();
}
}
據我所知,這將打開一個新的程序中運行
Start-Process
。我想在當前shell(即窗口)中運行命令 – keyneom您可以使用-NoNewWindow在當前shell中運行新的PowerShell進程。 –
如果我嘗試使用像get-location這樣的函數,則會出現以下錯誤:啓動過程:由於錯誤,無法運行此命令:系統找不到指定的文件。當我嘗試使用時出現此錯誤-NoNewWindow開關啓動過程:參數集無法使用指定的命名參數解決。' – keyneom
