29003 192.168.5.170:29003
29093 192.168.5.169:29093
[root@localhost company]# for i in `cat nat.cfg |awk '{print $2}'`;do grep $i nat.cfg;grep $i nat.cfg|wc -l;done

[root@localhost company]# cat chuli.py
import os
cmd = "for i in `cat nat.cfg |awk '{print $2}'`;do grep $i nat.cfg|wc -l;done"
num_cmd = os.popen(cmd)
while True:
i = num_cmd.readline().strip()
if i == '':
break
else:
if i >1:
print 'need delete %s'%i
else:
pass
[root@localhost company]# python chuli.py
