现在有另一个顽疾，一直没解决，最后跑完的结果，根据线程池的大小，结果是不一样的。比如 60 个线程的时候，结果是 3300，50 个线程的时候结果是 3000.。。。真要哭了，是 ssh 的坑么

win，linux，加 powershell 7 preview 版，若是 linux 则用 sshpass+ssh。

$a = get-content ip.txt
$a | ForEach-Object -ThrottleLimit 50 -Parallel {
# sshpass ssh ip 等
}

powershell [强] [简] 死你！
=========安装==========
你需要把 powershell 改成 powershell-preview，即安装非稳定版的 powershell。

centos7 及以上，安装 powershell:
curl -o /etc/yum.repos.d/microsoft.repo https://packages.microsoft.com/config/rhel/7/prod.repo
sudo yum remove -y powershell #删除旧版
sudo yum install -y powershell
pwsh -c 'mkdir -p "$env:HOME/.config/powershell" '
pwsh -c 'Add-Content -Value "Set-PSReadlineOption -EditMode Windows" -LiteralPath $profile '
pwsh -c 'Add-Content -Value "`nSubsystem powershell /usr/bin/pwsh -sshs -NoLogo -NoProfile" -LiteralPath /etc/ssh/sshd_config '

ubuntu1604：
sudo curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo curl -o /etc/apt/sources.list.d/microsoft.list https://packages.microsoft.com/config/ubuntu/16.04/prod.list
sudo apt-get update
sudo apt-get remove -y powershell #删除旧版
sudo apt-get install -y powershell
pwsh -c 'mkdir -p "$env:HOME/.config/powershell" '
pwsh -c 'Add-Content -Value "Set-PSReadlineOption -EditMode Windows" -LiteralPath $profile '
pwsh -c 'Add-Content -Value "`nSubsystem powershell /usr/bin/pwsh -sshs -NoLogo -NoProfile" -LiteralPath /etc/ssh/sshd_config '

ubuntu1804：
sudo curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo curl -o /etc/apt/sources.list.d/microsoft.list https://packages.microsoft.com/config/ubuntu/18.04/prod.list
sudo apt-get update
sudo apt-get remove -y powershell #删除旧版
sudo apt-get install -y powershell
pwsh -c 'mkdir -p "$env:HOME/.config/powershell" '
pwsh -c 'Add-Content -Value "Set-PSReadlineOption -EditMode Windows" -LiteralPath $profile '
pwsh -c 'Add-Content -Value "`nSubsystem powershell /usr/bin/pwsh -sshs -NoLogo -NoProfile" -LiteralPath /etc/ssh/sshd_config '

debian9：
sudo apt-get update
sudo apt-get install curl gnupg apt-transport-https
curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main" > /etc/apt/sources.list.d/microsoft.list'
sudo apt-get update
sudo apt-get remove -y powershell #删除旧版
sudo apt-get install -y powershell
pwsh -c 'mkdir -p "$env:HOME/.config/powershell" '
pwsh -c 'Add-Content -Value "Set-PSReadlineOption -EditMode Windows" -LiteralPath $profile '
pwsh -c 'Add-Content -Value "`nSubsystem powershell /usr/bin/pwsh -sshs -NoLogo -NoProfile" -LiteralPath /etc/ssh/sshd_config '

新增并发参数
| ForEach-Object -Parallel

例子:
1
get-content ip.txt |foreach-object -Parallel{ ping.exe $_ }

2
Get-Content /powershell/ip.txt |ForEach-Object -Parallel {if (Test-Connection -Count 1 -TargetName $_ -Quiet) {$_} } 6>$null

3
$a = 1..100
$a | ForEach-Object -ThrottleLimit 5 -Parallel {
Write-Host $_
Start-Sleep -Seconds 3
}

手册：
https://github.com/PowerShell/PowerShell-RFC/blob/master/4-Experimental-Accepted/RFC0044-ForEach-Parallel-Cmdlet.md

参数：
-Parallel
-ThrottleLimit
-TimeoutSeconds parameter takes an integer that specifies the maximum time to wait for completion before the command is aborted
-AsJob

$a = get-content ip.txt
$a | ForEach-Object -ThrottleLimit 50 -Parallel {
sshpass -p ‘xxx’ ssh user@ip #详细命令略
if ($LASTEXITCODE -ne 0)
{'xx'} else {'yy'}
}

talk is cheap ,show me code .
在安装 bash，python，powershell 的情况下，还有比这更简单的代码么？你倒是贴出来呀。
