python代替shell脚本_python的简洁是shell无法代替的

之前线上服务器分发配置都是用shell和expect脚本分发，脚本写了很长，上周换了ansible，现在自己用python写一个，就30行代码就可以实现需求，之前的shell写了快200行了，蛋疼，代码如下：

from multiprocessing import Process

import paramiko

import sys

file = sys.argv[1]

Username = "root"

Password = "123456"

Dest_Path = [

"/data/x5online/%s" %file,

"/tmp/%s" %file

]

Port = 22

def sftpPut(ip):

try:

s = paramiko.Transport((ip,Port))

s.connect(username=Username,password=Password)

sftp = paramiko.SFTPClient.from_transport(s)

localFile = file

for remoteFile in Dest_Path:

sftp.put(localFile,remoteFile)

print("%s put successful." %ip)

except:

print("%s not exits."%ip)

def ipProcess():

for i in range(10,40):

ip = '192.168.170.%s'%i

p = Process(target=sftpPut,args=(ip,))

p.start()

if __name__ == '__main__':

ipProcess()
