  This works:

    os.system("ls -al > foo")

  Perhaps more usefully, though, the "commands" module allows you to get the
output of a program as a string:

    foo = commands.getoutput("ls -al")

  And it might be helpful to know that Python itself has functions for
listing files:

    fileList = os.listdir(".")

  As well as for getting information about them:

    fileMTimes = [os.path.getmtime(f) for f in os.listdir(".")]
    filePermissions = [os.stat(f).st_mode for f in os.listdir(".")]

  For more information, see http://www.python.org/doc/lib/
