Hi,
I am having difficulty with shell scripting in Python.
I use the following command to run a DOS command and put the return value in
a Python variable:
print os.popen('DIR').read()
It works very fine with DIR command, but for commands like "MD :" it doesn't
return the error message into the string:
print os.popen('MD :').read()
# No error message
When I use Ruby, it works perfect:
`md :`
The filename, directory name, or volume label syntax is incorrect.
I am also having problem with redirecting the python script output to a
file: That means I can redirect the output to a file by using pipes like
this:
Python.exe script.py >file.txt
But the sequence of contents in file.txt doesn't match with command
execution sequence!
When I don't use pipes, the output sequence is fine when I see the output on
the monitor screen.
Am I missing anything? Considering the fact that Ruby doesn't have any
problem with redirecting STDOUT into files or string variables, is Python
the right tool for this kinds of shell scripting?
Any help would be appreciated,
Alan
