英文:
discovery if ICMPv4 inbound is allowed on firewall
问题
尝试列出 Windows 防火墙上允许的 ICMPv4 入站规则（以便在批处理/PowerShell混合脚本中处理）
powershell.exe "Get-NetFirewallPortFilter -Protocol icmpv4 | Get-NetFirewallRule | ft enabled,direction,action"
这会给我大约10个结果。如何仅筛选具有 "Enabled=True" 和 "Direction=Inbound" 的结果？我可以使用 findstr 来筛选脚本输出，但最好在 PowerShell 中完成这个任务。
英文:
Trying to list ICMPv4 Inbound Allowed rule on windows firewall (to process in batch/ps hybrid script)
powershell.exe "Get-NetFirewallPortFilter -Protocol icmpv4 | Get-NetFirewallRule | ft enabled,direction,action"
This give me about 10 results. How to filter only results which have "Enabled=True" and "Direction=Inbound"? I am able filter script output by findstr, but shoud be better to do this in powershell.

你应该使用 Where-Object：
powershell.exe "Get-NetFirewallPortFilter -Protocol icmpv4 | Get-NetFirewallRule | Where-Object {`$_.Enabled -eq 'True' -and `$_.Direction -eq 'Inbound'} | ft enabled,direction,action"
