A more safe way to run shell command is using "check_output" function. If the return value if not 0, a exception raised, otherwise return the command output. $ cat myrun.py import subprocess def run(cmd):returnsubprocess.check_output(cmd, shell=True) $ python -i myrun.py >>> ret ...
os.system(command) 这个函数可以调用shell运行命令行command并且返回它的返回值。试一下在python的解释器里输入os.system(”ls-l”),就可以看到”ls”列出了当前目录下的文件。可以说,通过这个函数,python就拥有了shell的所有能力。呵呵。。不过,通常这条命令不需要用到。因为shell常用的那些命令在python中通常有对应...

forcommandincommands:subprocess.run(command,shell=True) 1. 2. 在这个例子中,我们使用for循环逐个遍历命令列表中的命令。然后,我们使用subprocess.run()函数来执行每个命令。shell=True参数告诉函数使用Shell来执行命令。 6. 检查命令执行结果 如果你想要检查每个命令的执行结果,可以使用subprocess.run()函数的返回值。
似乎是Using Python to open a shell environment, run a command and exit environment的复制品。我想在Redhat的shell环境中运行ulimit命令。步骤:打开shell环境,在shell上运行ulimit命令,获取结果,退出shell环境。参考上面的解决方案,我尝试了: 代码语言:javascript 运行 AI代码解释 from subprocess import Popen, PIPE...
# execute a command with arguments in a subprocess process = await asyncio.create_subprocess_exec('ls', '-l') 我们可以通过等待 wait() 方法来等待子进程完成。 ... # wait for the subprocess to terminate await process.wait() 我们可以通过调用 terminate() 或 kill() 方法直接停止子进程,这将在...
The first and the most straight forward approach to run a shell command is by usingos.system(): importosos.system('ls -l') If you save this as a script and run it, you will see the output in the command line. The problem with this approach is in its inflexibility since you can’...
