How can I execute shell commands from within python. Specifically, I
am looking for something like the shell "cat". But this also made me
wonder how to execute shell commands anyway, just if i needed to do
that in the future. 7 66688

You can use os.system() for that.

You can use os.system() or os.popen(), etc.

that's an old thread, and Python has grown a few more ways to
deal with shell commands since then. if os.system isn't good en-
ough for you, subprocess is the preferred alternative: http://www.python.org/doc/lib/module-subprocess.html
(also note that most trivial shell commands are better done in
python. most uses of cat, for example, can be trivially emulated
with one or two lines of python...)
</F>
use subprocess module
from subprocess import call
call(['cmd', 'arg1', 'arg2'], stdin='...', stdout='...')
eg:
call(['ls', '-l'])

Though the knowledge required to do this may be more trivial
for some of us than others! "cat" probably doesn't have much
going for it that a naive implementation would miss - some
versions will recreate "holes", but most applications will never
miss this. You can replace "mv" with os.rename() if you don't
care that it will fail when the destination is on a different
filesystem. Etc.

If you care than use `shutil.move()` instead.

Basically, we are trying to add a few lines to this script that will

I remember that there is a function that could invoke shell command
such as "rm" "cp", directly in .c file. But I could not recall its
name, and I googled with nothing meaningful. I vaguely remember it is
like:
foo("cp file1 file2");
it is that simple, but cant remember. Could anyone here give me a
clue?

Hello! :)
I'm trying to run shell commands both with os.system() and
subprocess.Popen() class.
But I can't run aliases or function defined in my .bashrc file, like in
the login interactive shell.
Can you help me?
Maybe have I to add some commands to load the .bashrc?

Please see the following code.
Suppose I have many shell commands to be executed. And I don't want to
fork a sub shell for each command(eg: status,output =
commands.getstatusoutput(cmd)) because it is too expensive. I want to
use only one sub shell to execute all these commands and want to get
each command's output. How can I accomplish this task ? Thanks in
advance.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
