ACL allows you to set permissions for groups or final users. The standard commands for working with ACL, setfacl and getfacl, are well detailed in the manual, so we would rather stick to examples. Make sure the filesystem on the disk that stores this directory supports ACL. Let us create the Manager directory, which all users, belonging to the group manager, will be allowed to read and write: The second command sets the same permissions for all users that belong to the manager group.

Whenever the root user or any user of the manager group creates files and directories, they will will inherit the access attributes.

Access Granted!

To view permissions in console mode, execute: Enlarge the window to see all the attributes. To modify an existing rule or add a new one, use the -m parameter, as shown below. If the group option is omitted, permissions will be set for the group that owns the file. To do so, use the default identificator or the -d parameter.

However, the default permissions will not be applied to the first directory. Since r, the read access rights are needed to read a file, while you will need rx, the read and execute rights to read a directory, you should probably specify X instead of x when setting permissions.

The X flag assigns permissions only to those files and directories that already have the execute access right. The X flag is calculated on the moment when setfacl is launched, that is why it is interpreted as x in the default rules. While in the first case, the peter user will be granted the execute right to all the newly created files in folder and its subdirectories, in the second case the user will not be able to read the new directories.

This parameter can be combined with -m, if you want to substitute permissions. The M parameter does that; it allows you to set permissions from a file or a standard input stream.

It means, for example, that you can prevent all users from writing to a file by setting the effective mask r-x. To initialize a mask, set it to rwx.

If the user is the file owner, the owner's permissions are applied. User-specific rights to this file are applied. Access is granted, if the user belongs to at least one group that has access to it. If the user does not belong to any group defined in ACL, the other permissions are applied.File permissions and attributes.

So what I struggled with for a long time is the fact that when you are coming from unix/Linux, the permissions on the source file matter. I had the umask set as , above, and my files kept getting uploaded to the remote server as To determine the umask value you want to set, subtract the value of the permissions you want from (for a file) or (for a directory).

The remainder is the value to use with the umask command. For example, suppose you want to change the default mode for files to (rw-r--r--).
