Comparison operators act like filters when applied to arrays. So any console command that outputs multiple text lines can be used with comparison operators.

This example will use netstat.exe to get only established network connections, then to get only established network connections to any server that has "stor" in its name, and then uses ipconfig to get the current IPv4 address:

PS C:\> @(netstat) -like '*establ*'
  TCP 192.168.0.10:49863 BatHome01:1080       ESTABLISHED
  TCP 192.168.0.10:49864 BatHome02:1080       ESTABLISHED
  TCP 192.168.0.10:49866 HomeBat01:1080       ESTABLISHED
  TCP 192.168.0.10:49898 HomeBat02:1080       ESTABLISHED

The trick is to enclose the console command in @() which makes sure that the result is always an array.

可以用 Select-String 来代替 -like

netstat | Select-String "establ"
