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/pythonimport pexpectimport sysimport timeimport osnow = 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()
