with `shell=True` Python will directly execute `/bin/sh` , without any searching (passing the argument `executable` to `Popen` can change this,似乎如果它是一个没有斜杠的字符串,那么它会被 Python 解释为 shell 程序的名称,以在当前进程的环境

subprocess.getoutput(cmd) 接收字符串格式的命令,执行命令并返回执行结果,其功能类似于os.popen(cmd).read()和commands.getoutput(cmd)。 subprocess.getstatusoutput(cmd) 执行cmd命令,返回一个元组(命令执行状态, 命令执行结果输出),其功能类似于commands.getstatusoutput()。

在Python中,使用subprocess.Popen来执行外部命令并传递参数是一个常见的操作。下面我将根据给出的提示,详细解释如何使用subprocess.Popen来执行命令并传递参数。 1. 导入subprocess模块 首先,你需要导入Python的subprocess模块,它提供了启动新进程、连接到它们的输入/输出/错误管道以及获取它们返回码的功能。 python import ...
