MATE Eiciel
Graphical editor for ACLs and xattr for MATE Desktop
MATE Eiciel is a standalone tool and a Caja plugin to graphically edit Access Control Lists (ACL) of your files. ACLs allow to set more fine-grained permissions than the traditional Unix permissions of user, group, other (UGO permissions). It's based on Eiciel by Roger Ferrer.
MATE Eiciel also allows to edit the extended attributes of files and directories if the filesystem supports it.
Not all filesystems support ACLs and extended attributes. And even for those supporting them, they must be enabled (by the system administrator) before using MATE Eiciel.
MATE eiciel is a Graphical editor for access control lists (ACLs) and extended attributes (xattr), either as an extension within Caja, or as a standalone utility.
