- wanted to give read/write/execute permission to group
- but did not want to end up with 'executable' .cpp and .h files
If I give 'chmod g+rwx -R dir' then all users belong to my group will be able to access these files but it looked ugly to me. What I wanted was to copy user permissions to group so all users of my group can have same permission as me.
Solution was so simple (now I think that why I didn't check man pages earlier..)
chmod g+u -R dir
Thats it and its done.
