Python Expect模块
Python中有一个pExpect模块,和TCL中的expect命令差不多，通过expect可以使你的脚本和shell命令之间进行交互。
下面python脚本，使用了expect与ssh和scp交互来完成任务。
#!/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 == '-c':
foo = pexpect.spawn('scp -r %s user@address.org:/home/user/' % sys.argv)
foo.expect('.ssword:*')
foo.sendline('password')
foo.interact()
elif sys.argv == '-b':
os.mkdir("/home/user/BKUP/foo.com%s" % now, 0700)
foo = pexpect.spawn('scp -r user@foo.org:/RemoteBox/user/%s /LocalBox/user/Bup/foo%s/' % (sys.argv, TimeStamp))
foo.expect('.*ssword:')
foo.sendline('Passwd_to_server')
foo.interact()
elif sys.argv == '-p':
foo = pexpect.spawn('ssh foo@bar.com')
foo.expect('.*')
foo.sendline('password')
foo.interact()
else:
foo = pexpect.spawn('ssh default@default.org')
foo.expect('.*ssword:')
foo.sendline('password')
foo.interact()
