這篇文章主要介紹了通過(guò)python連接Linux命令行代碼實(shí)例,文中通過(guò)示例代碼介紹的非常詳細(xì),對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下
代碼如下
#!/usr/bin/python # -*- coding: utf-8 -*- '''https://www.ibm.com/developerworks/cn/linux/l-cn-pexpect2/index.html''' import pexpect import types username = "root" ip = "192.168.***.***" password = "****" pex = pexpect.spawn('ssh %s@%s' % (username, ip)) def _check(pattern, timeout=120): i = pex.expect(pattern, timeout=timeout) return i def sendcr(cmd): if pex == None: return 0 n = pex.send("%s\r" % cmd) return n def getexec(cmd): child = pexpect.spawn(cmd) child.expect(pexpect.EOF) return child.before if __name__ == '__main__': checklist1 = [["(?i)Connection refused", False], ["(?i)Host key verification failed.", False], ["(?i)VENUSTECH AUDIT SYSTEM MA1000", True], # ["(?i)#\[/]",True], # hpux ["(?i).+>", True], # windows [".+[>$#]\s*$", True], # debian ["(?i)Last login", True], ["(?i)access denied", False], ["(?i)NT_STATUS_LOGON_FAILURE", False], ["(?i)are you sure you want to continue connecting", "yes"], ["(?i)authentication fail(?!ure)", False], ["(?i)connection closed by remote host", False], ["(?i)login failed", False], ["(?i)login incorrect", False], ["(?i)need to be root", False], ["(?i)no route to host", False], ["(?i)not found", False], ["(?i)Bad secrets", False], ["(?i)incorrect password", False], ["(?i)permission denied", False], # ["(?i)terminal type",terminal_type], ["This private key will be ignored.", False], ["(?i)no route to host", False], ["(?i)press 'Enter' key to proceed", "\r"], ["(?i)Y/N", 'Y'], [pexpect.EOF, False], [pexpect.TIMEOUT, False], ["(?i)Enter passphrase for key .*:", password], ["(?i)assword", password], ["(?i)passwd", password], ["(?i)sername", username], ["(?i)(?<!sful )login", username], ["(?i)----------------------------------------------------------------", True]] checklist2 = [i[0] for i in checklist1] while True: i = _check(checklist2) print i, checklist1[i], checklist1[i][1] if (type(checklist1[i][1]) is types.BooleanType): if type(checklist1[i][1]): break else: sendcr(checklist1[i][1]) cmd = "ls -l /etc/rsyslog.conf" result = getexec(cmd) print "result", result
打印結(jié)果:
26 ['(?i)assword', '***'] *** 5 ['(?i)Last login', True] True result -rw-r--r--. 1 root root 3167 Mar 13 11:24 /etc/rsyslog.conf
