Find process running on port in Windows

Find process running on port in Mac

  • macOS icon_os_mac.png
    • netstat -vanp tcp | grep 4444 or
    • lsof -i tcp:4444 or lsof -i :4444[2]
    • sudo lsof -i -P | grep LISTEN | grep :$PORT[3]

Find process running on port in Windows

  • Linux Os linux.png CentOS7:
    • netstat -na | grep ":<port>" e.g. sudo netstat -pan | grep ":80" or
    • ps -elf | grep <port>
## windows
## After running process on windows, and then input the command: netstat –na | find "4444"

問題排除

FIND: 參數格式不正確

問題: Win Os windows.png netstat –na | find 4444 輸入後遇到「FIND: 參數格式不正確」錯誤訊息。

解決方式: 請將 <port> 加上雙引號，例如: netstat –na | find "4444"
