Question

I want to share a folder among all users of a group : dev. So that all files are regardless of the owner can be edited by anyone in the group.

I have created the shared folder and set the respective permissions to the folder.

When a user creates a new file in that folder it belongs to owner:dev
But the permission for the files are rw-r–r–
So other users who belong the same group are not able to edit the files.

Like default group become “dev” how can I set the default permission for the files created in that directory.

I don’t want to use “umask” technique because the user will upload files into that directory throuh ftp and other tools.

This really belongs on serverfault and I already mentioned there’s almost an exact duplicate there, but anyway there’s a nice little solution you can use, which is the FUSE bindfs module (there’s a package in ubuntu). You use it to mount one directory onto another mountpoint and can set things such as the default permissions of any files created here, their owner, group and the permissions of files already in the directory (which is what you seem to want).
