linux 根据端口号查找对应的程序目录

1：根据端口号查找对应的进程 id
(1): [root@192 local]# lsof -i:6122
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 22775 root 42u IPv6 7350952 0t0 TCP *:bex-webadmin (LISTEN)
[root@192 local]#

(2): [root@192 local]# netstat -apn|grep 6122
tcp 0 0 :::6122 :::* LISTEN 22775/java
[root@192 local]#
得到进程 id = 22775

2：根据进程 id 查找程序目录
[root@192 local]# cat /proc/22775/environ
