Up to 1024 bytes seems nothing, but maybe I do not exactly understand what do you mean for "group usage". In which way this limitation has been done? If using quotas, you can check the group usage by
On the other end, if you want to know how much space is used by all the files belonging to a specific group, you can do something like:
Code:
find / -type f -group users | xargs ls -l | gawk '{usage += $5} END {print usage}'
This will return the amount in bytes of all the files which belong to the group "users". Just a warning: this command may take a long time to execute, depending of the number of files found!
