I am a newbie of Python and I would like to write a Python program that can execute some command in the cmd and get the output from it automatically.
Is it possible? How can I do this?
Thanks in advanced!
You will want to use
>>> import subprocess >>> r = subprocess.Popen(['ls', '-l']) #List files on a linux system. Equivalent of dir on windows. >>> output, errs = r.communicate() >>> print(output) Total 72 # My file list here
Popen-construtor accepts a list of arguments as the first parameter. The list starts with the command (in this case
ls) and the rest of the values are switches and other parameters to the command. The above example is written as
ls -l on the terminal (or command line, or console). A windows equivalent would be
>>> r = subprocess.Popen(['dir', '/A'])
