Is there is any way to create a special directory, where all the new files created and all the new directoris created under this special directory, wered create with permissions of write and read for all the users?

Thanks

1) Create a directory and then chown :groupname directory where groupname is a common group that all your users belong to.

2) chmod -R 666 directory -- this sets the directory permissions to read and write for everyone

3) chmod g+s directory -- this sets the "sticky bit", which means all files in this directory will be created with the same group permissions as the directory.

So if you have a directory like and set the sticky bit, the directory permissions will look like and all files will be created with read write group permissions.

I have tried it, but I have some problems if I change permissions of the directory to 666, the other users can't enter to the directory, I have to use 770 permisions to allow all the users of my group to enter to the directory.

And another problem that I have is that using sticky bit, I have created this directory named prova

327253 4 drwxrws--- 2 root marc 4096 jun 6 17:59 prova/

Directory prova has read and write permissions for group but when I create a file named p2, inside the directory

327253 4 drwxrws--- 2 root marc 4096 jun 6 18:07 ./
2 4 drwxr-xr-x 20 root root 4096 jun 6 18:04 ../
327255 4 -rw-r--r-- 1 prova marc 2 jun 6 18:07 p2

Only have write permissions the user, the group not, but It's is a sticky directory, I don't understand why the file is created with out write permissions for the group

Yes, DIRECTORIES NEED EXECUTABLE PERMISSION. Executable is the most important permission for directories. It allows people to enter the directory (and access its contents). Read permission allows listing of the directory, but is otherwise unimportant. Write permission allows creating and deletion of contents. That's why "6" is completely useless; directory permissions usually consist of 7, 5, or 1.
