execute a shell script from a python script

[spec]

Hi all, I know nothing about Python. What I need to do is to get a
Python script to execute a local shell script. I do not need any
output. What would be th eeasiest way to accomplish this?

Thanks!

Re: execute a shell script from a python script

If your script is foo.sh and takes args:
import subprocess
subprocess.call (["foo.sh","a rgs"],shell=True)
Should work fine. check out

Thanks, actually there are no args, is there something even simpler?

Thanks

Check out os.popen4 or the commands module.

you could try os.system()

>From the docs:

system(command)
Execute the command (a string) in a subshell. This is implemented
by calling the Standard C function system(), and has the same
limitations. Changes to posix.environ, sys.stdin, etc. are not
reflected in the environment of the executed command.

On Unix, the return value is the exit status of the process encoded
in the format specified for wait(). Note that POSIX does not specify
the meaning of the return value of the C system() function, so the
return value of the Python function is system-dependent.

On Windows, the return value is that returned by the system shell
after running command, given by the Windows environment variable
COMSPEC: on command.com systems (Windows 95, 98 and ME) this is always
0; on cmd.exe systems (Windows NT, 2000 and XP) this is the exit status
of the command run; on systems using a non-native shell, consult your
shell documentation.

Availability: Macintosh, Unix, Windows.

Re: execute a shell script from a python script

As described in the docs I pointed to before:
subprocess.call ("foo.sh",shell =True)
Is the way to do it without args. I think it is simplest to learn the
subprocess module because (quoting from the docs) this module intends
to replace several other, older modules and functions, such as:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
This way you only need to learn one thing. Actually I would like to
see some of these older functions deprecated.

I'm concerned the follow-ups in this thread have been too subtle.
Here is what you need to know: use system(). A model such as

os.system("my_s cript")

fulfills exactly the requirements the original poster described.
