论python 和 shell的实用性

python实现

vi port.py
import socket
 
sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 
sk.settimeout(1)
 
try:
    sk.connect((‘127.0.0.1‘,22))
    print ‘Server port 22 OK!‘
 
except Exception:
    print ‘Server port 22 not connect!‘
 
sk.close()

shell实现

vi port.sh
#/bin/bash
port=`ssh 192.168.93.136 ‘netstat -atnulp | grep -w 0.0.0.0:22 | wc -l‘`

if [[ $port -eq 1 ]]
then
      echo -e " \033[32m port 22 ok !! \033[0m"
else [[ $port -eq 0 ]]
      echo -e " \033[32m port 22 not ok !! \033[0m"
fi
