3. commands.getstatusoutput(command) 使用os.popen()函数执行command命令并返回一个元组(status,output),分别表示command命令执行的返回状态和执行结果。对command的执行实际上是按照{command;} 2>&1的方式,所以output中包含控制台输出信息或者错误信息。output中不包含尾部的换行符。 4. subprocess模块 此模块在pytho...

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...
python中的shell操作 首先介绍一个函数: 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。
Next, theos.popen()command opens a pipe from or to the command line. This means that we can access the stream within Python. This is useful since you can now get the output as a variable: importosstream=os.popen('echo Returned output')output=stream.read()output ...
