Python SSH OS Tcl 腳本

Python中有一個pExpect
模塊,和TCL中的expect命令差不多，通過expect可以使你的腳本和shell命令之間進行交互。

下面python腳本，使用了expect與ssh和scp交互來完成任務。

 

#!/usr/bin/python

import pexpect
import sys
import time
import os

now = time.strftime("%m%d%y_%I%M%S%p", time.localtime())

if sys.argv[1] == '-c':
    foo = pexpect.spawn('scp -r %s [e-mail]:/home/user/' % sys.argv[2])
    foo.expect('.ssword:*')
    foo.sendline('password')
    foo.interact()

elif sys.argv[1] == '-b':
    os.mkdir("/home/user/BKUP/foo.com%s" % now, 0700)
    foo = pexpect.spawn('scp -r [e-mail]:/RemoteBox/user/%s /LocalBox/user/Bup/foo%s/' % (sys.argv[2], TimeStamp))
    foo.expect('.*ssword:')
    foo.sendline('Passwd_to_server')
    foo.interact()
elif sys.argv[1] == '-p':
    foo = pexpect.spawn('ssh [e-mail]')
    foo.expect('.*')
    foo.sendline('password')
    foo.interact()
else:
    foo = pexpect.spawn('ssh [e-mail]')
    foo.expect('.*ssword:')
    foo.sendline('password')
    foo.interact()
