执行shell命令
- 阻塞式命令调用方法:
def _executeCmd(cmd, isSudo=False): if isSudo: cmd.insert(0, 'sudo') status, output = commands.getstatusoutput(' '.join(cmd)) if status: raise Exception(output) return output
- 利用子进程执行命令调用方法(详细使用方法参见:subprocess模块):
def aaa(): sub = subprocess.Popen("ssh root@172.16.7.210 df /home", shell=True, stdout=subprocess.PIPE) try: sub.wait() return sub.stdout.read() except: print "aaa kill" sub.terminate()
