Re: [Tutor] system()? popen2()? How to execute a command & save its output?

2010-09-30 Thread r...@schoenian-online.de 
Hi,
 
I've once written a script to sync my website with a local directory. I guess
that you will find anything you need in the FTPHelper class. Have a look at:
http://home.arcor.de/ralf_schoenian/websync/index.html At the bottom of the page
you can view and download the script.
Any questions are welcome.
Ralf

You might also consider pexpect.
http://pexpect.sourceforge.net/

It's designed for interactive console applications like ftp.

For popen() style access, the recommended approach is the subprocess module.  
You should be able to find an example in the docs to fit your application.
http://docs.python.org/library/subprocess.html

Cheers

I'm needing to transfer the following shell construct to Python, plus save the 
output of execution:

FTP_SITE='ftp.somesite.com'
ftp -a  $FTP_SITE <http://mail.python.org/mailman/listinfo/tutor
