]]> The Access Control List (ACL) provides an extended set of permissions on files and directories, there are 2 commands available to use: setfacl, getfacl.

Consult man page for complete manual.

Sample use:

getfacl -c Video/

Gives out:

user::rwx
group::r-x
other::r-x

When it’s needed to share to others:

setfacl -m u:user2:5
getfacl -c Video/

Will return:

user::rwx
user:user2:r-x
group::r-x
mask::r-x
other::r-x

So user2 can only be read-only on this directory.

Removing all extended ACL and leave the default system rwx, use this command:

setfacl -b Video/
