Powershell随机颜色变化

Question

以前从未使用过Powershell，我试图在Powershell中重新创建以下Bash脚本：

而为true；do head-c200/dev/urandom|od-An-w50-x|grep-E--color"；([[：阿尔法：]][[：数字：]]({2}"；；睡眠0.5；完成

这是我得到的，但我希望它将随机线变成红色，而不是每五个实例；

while(Get-Random)
{
Start-Sleep -Milliseconds 10
Write-Host -NoNewline "   " (get-random) 
Start-Sleep -Milliseconds 30    
Write-Host -NoNewline "   " (get-random) 
Start-Sleep -Milliseconds 10
Write-Host -NoNewline "   " (get-random) 
Start-Sleep -Milliseconds 30    
Write-Host -NoNewline "   " (get-random) 
Start-Sleep -Milliseconds 10
Write-Host -NoNewline "   " (get-random) -ForegroundColor red
}

任何关于我如何设置"-ForegroundColor红色"；对于随机线路？

Answer 1

$color=@('gray','red')
while(Get-Random)
{   Start-Sleep -Milliseconds 10
Write-Host -NoNewline "   " (get-random) -ForegroundColor (Get-random $color)
}
