p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1) for line in iter(p.stdout.readline, b''): print line, p.stdout.close() p.wait() 实际弱口令我是这样写的 import subprocess #Popen proc = subprocess.Popen(medusaCMD, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)...
process = subprocess.Popen(cmd_string,stdout=subprocess.PIPE,\ universal_newlines=True,\ stderr=subprocess.PIPE,\ shell=False) while True: if p.poll() is not None: break: outstr = process.read() #此处会阻塞 sleep(1) 简单说明: # ***obj.read(),obj.readline(),需要读取EOF字符或\n标志...
subprocess意在替代其他几个老的模块或者函数,比如:os.system os.spawn* os.popen* popen2.* commands.* 一、subprocess.Popen subprocess模块定义了一个类: Popen class subprocess.Popen( args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=...
>>> p = subprocess.Popen(args) # Success! 1. 2. 3. 4. 5. 6. 7. Popen它的构造函数如下: subprocess.Popen(args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startup...
print(sbpss.stdout.read()) 1. 2. 3. 4. 2、decode() import subprocess sbpss = subprocess.Popen('echo 你好',shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE) print(sbpss.stdout.read().decode('gbk')) 1. 2. 3. 4. 3、text=True(推荐,不需要考虑编码格式) ...
stdout, stderr:input: 该参数是传递给Popen.communicate(),通常该参数的值必须是一个字节序列,如果universal_newlines=True,则其值应该是一个字符串。 run()函数默认不会捕获命令执行结果的正常输出和错误输出,如果我们向获取这些内容需要传递subprocess.PIPE,然后可以通过返回的CompletedProcess类实例的stdout和stderr属性...
P=subpross.Popen(cmd,stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE,shell=True) reshult=p.stdout.read() 以下是执行过程中出现的异常,请问是什么原因? Traceback (most recent call last): File "ping.py", line 3, in <module> ...

Python subprocess.Popen用法及代码示例 用法: classsubprocess.Popen(args, bufsize=-1, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=True, shell=False, cwd=None, env=None, universal_newlines=None, startupinfo=None, creationflags=0, restore_signals=True, ...
>>> print child1.stdout.read(), #或者child1.communicate() >>> import subprocess >>> child1 = subprocess.Popen(["cat","/etc/passwd"], stdout=subprocess.PIPE) >>> child2 = subprocess.Popen(["grep","0:0"],stdin=child1.stdout, stdout=subprocess.PIPE) ...
