Hi, I am trying to call 'zip'(linux) from within my python external method. The is what I do: ### SRC ### import os src_dir = 'some_dir' cmd_apth = '/usr/bin/zip' zip_file_name = 'res.zip' os.chdir(src_dir) result = os.spawnl(os.P_WAIT,cmd_path,'-rv',zip_file_name,'.') print result ### END SRC ### the result is always 12 (zip error: Nothing to do). zip creates the directory structures in the zip file but does not put in the actual files. Now if I do an os.system instead of an os.spawnl it works, however I do not want to use it. What is going on here?? Also I have been able to use 'unzip'(Linux) in the same manner without a hitch. So what am I doing wrong here?? Why shouldnt it work?? TIA AM PS: I have played around with the Python ZipFile and zlib module. Didnt feel comfy so going with this as of now, will probably switch over later. ------------------------------------------------------------------------
