First:
import os
import time
source =['/home/caifei/视频/听风者1.rmvb','/home/caifei/视频/听风者2.rmvb']
target_dir='/home/caifei/important_backup/'
target=target_dir + time.strftime('%Y%m')+'.zip'
zip_command="zip -qr '%s' %s" % (target, ' '.join(source))
if os.system(zip_command)==0:
print 'Successful backup to', target
else:
print 'Backup Failed'

Second:
zip I/O error: Permission denied
zip error: Could not create output file (/home/caifei/important_backup/201405.zip)
Backup Failed



The First is my procedure. When I run it, I will face with the problem, shown in the Second, which I can not resolve. Please tell me how to resolve this problem completely and what I must do for my procedure. Thank you.

looks interesting, but so much is missing from this thread...

please read the link in my signature.

please use [code]here comes your script[/code] to keep formatting (which is specifically for python is very important).

probably the target directory does not exist.
to improve your code please try subprocess.popen instead of os.system. see for example here: http://www.cyberciti.biz/faq/python-...mand-examples/ and print the error message.

Hi this is the exact same problem i am having i so hope you managed to sort it out and somehow get to see this message so you can help me sort this out

As a atart, run it with 'strace -f python yourscript.py 2>strace.log' and look for errors in strace.log

I don't know what information everyone thinks is missing. The problem is obviously that the script is being run under an account that doesn't have permission to create (or write to) that zip file in /home/cafei.

You could have easily debugged this by executing the zip command by hand.

Thanks for the reply's and i did think it was as dugan had said about not having the relevant permissions to execute the script, which is what it was but rather than running the zip command by hand as this would have ment doing that each time i presume, i managed somehow to alter the directory permissions and now it's working fine sorry i'm extremely new to all this so if i sound like i dont have a clue thats because i dont , currently happy fumbling around trying to learn, so if anyone can point me in the direction of the best places for Tutorials for Linux itself and also Python, Flask and also Glade i would appreciate it.

Many Thanks -- GillysWindows(Wayne).

The best resource for Flask is honestly the Flask homepage.

As for beginner's Python material, it's an embarrassment of riches. These are pretty common recommendations:

https://developers.google.com/edu/python/?csw=1
http://www.greenteapress.com/thinkpython/
http://www.swaroopch.com/notes/python/

I think the last one might be for Python 3.
