powershell，复制bash Parallel Ping

我看到了这一点，喜欢它是a）在本地狂欢中，b）并行运行，因此不到一秒钟的时间来扫描子网。运行：/inline-ip.sh 192.168.1

#!/bin/sh
# online-ip.sh
echo "Online IPs" > online-ip.txt
COUNTER=1

while [ $COUNTER -lt 255 ]
do
    ping $1.$COUNTER -c 1 -w 400 | grep "icmp" >> online-ip.txt &
    COUNTER=$(( $COUNTER + 1 ))
done
killall ping
cat online-ip.txt

我们可以在PowerShell中做得像PowerShell一样快速有效吗？我知道powershell 6+中的foreach -object -parallel ，但我的工作服务器都锁定为PS 5.1；肯定是5.1足够好，可以做一些简单的并行操作吗？我知道nmap -sp之类的事情，但是如果Bash可以在本地进行此操作，那么PS 5.1也可以吗？

如果这样的脚本可以返回发现IPS的系统的主机名和操作系统（我认为PowerShell在可能的情况下具有更轻松地提取信息的优势），这也对我来说非常有用。？

原文

I saw this and liked that it was a) in native bash, and b) runs in parallel so takes less than a second to scan the subnet. Run with: ./online-ip.sh 192.168.1

#!/bin/sh
# online-ip.sh
echo "Online IPs" > online-ip.txt
COUNTER=1

while [ $COUNTER -lt 255 ]
do
    ping $1.$COUNTER -c 1 -w 400 | grep "icmp" >> online-ip.txt &
    COUNTER=$(( $COUNTER + 1 ))
done
killall ping
cat online-ip.txt

Can we do something as fast and efficient as this in PowerShell, also in parallel? I know of ForEach-Object -Parallel in PowerShell 6+ but my work servers are all locked to PS 5.1; surely 5.1 is good enough to do a bit of simple parallel operations? I know of things like nmap -sP, but if bash can do this natively, surely PS 5.1 can too?

It would also be extremely useful to me if such a script could return the hostname and OS of the systems at the found IPs (I think that PowerShell has the edge over bash for more easily extracting information) if possible?
