Mac的命令与Linux的命令有不少差异:

查看端口的状态

$ netstat -anp tcp | grep 3306

查看所有Listen的端口

依据端口号查进程号

在Mac上，命令是lsof -i:$port。

$ lsof -i:8080

COMMAND   PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

node    12159 yyyyyy   23u  IPv4 0x76b4f5051c4983f3      0t0  TCP *:netxms-agent (LISTEN)

通常在Linux下使用netstat -ntpl | grep 8080，各参数的含义是：

• -n表示不显示host_name，显示number。
• -t表示显示TCP。
• -p表示展示进程号process。
• -l表示展示Listen的端口。

而lsof命令通常用来查看某个进程的open files列表。
