hi
We have a folder structure of
folder1
which has oracle:dba privileges as does its subfolders and they are created 750.
I want a user to scp in to see the structure in folder1 and have access to the directories in it but not put them in the dba group.
Could i create a newgroup and acl on the newgroup for folder1 and it will propogate the acl to existing folders and to new ones that are created in there ?
If not any other ideas how to achieve ?

To modify the ACLs for existing directories, you could:

find folder1 -type d -exec setfacl -m group:newgroup:r-x {} \;

This will allow a user in "newgroup" to cd and ls the contents of folder1 and all its subdirectories.  

This modified ACL will not have any effect on newly created directories in folder1.  For that you would have to create default ACLs on the directories.

So if I did -
setfacl -m group:newgroup:r-x folder1
it would then propogate to all the existing directories?
and to cover for new directories i'd need to set a default acl - would something like this work ?

setfacl -d group:newgroup:r-x folder1 and it would go to new directories created later below folder1 ?

The acl commands work on a named file or directory. They don't propagate to subdirectories which is why I would use it as an argument to the find command.

To set the default acls on folder1 and all subdirectories, you could do this (one line, split into two using \):

find folder1 -type d -exec \
setfacl -m d:user::rwx,d:group::r-x,d:other:---,d:mask:r-x,d:group:newgroup:r-x {} \;

-m  <--- modify the existing owner/group/other

d:user::rwx,d:group::r-x,d:other:---  <--- will modify the existing owner/group entries so that all new files and directories have these permissions. (Notice only on : after other.)

d:mask:r-x  <--- the highest allowable permissions besides the owner's permissions

d:group:newgroup:r-x  <--- the group you want to have read/execute permissions.  Or you could add a specific user (d:user:username:r-x).

ACLs are messy, btw.
