系统批量运维管理器pexpect的使用

# pip install pexpect 或 # easy_install pexpect

1 #!/usr/bin/env python
2 import pexpect
3 child = pexpect.spawn('/usr/bin/scp /root/pexpect/haha 172.16.65.201:/tmp/')
4 child.expect('password:')
5 child.sendline('rootroot')
6 child.expect(pexpect.EOF)   #匹配结束语句

 #!/usr/bin/env python
 import pexpect
 import sys
 child = pexpect.spawn('ssh root@172.16.65.201')
 fout = file('mylog.txt','w')
 child.logfile = fout  #输出写到日志文件
 #child.logfile = sys.stdout  #输出到标准输出 （好像只能同时二选一）

 child.expect('password:')
 child.sendline('rootroot')
 child.expect('#')
 child.sendline('ls /home')
 child.expect('#')
 #print "before:"+child.before
 #print "after:"+child.after
