Hello every body.
Every morning at 7, a cron task is launched (with command php) and so create the log file for the day.
But this file's permission is -rw-r--r-- with user "bob" and group "www-data".
So the file is not writeable by www-data and the log file is not filled for the rest of the day.
The permission for logs directory is "drwxrwsr-x".
The umask of bob is 0007.
Os : debian jessie
How can change the default permission ?
In advance, thank you
