Définition des droits root — root privileges

 

Il existe un critère décisif d'appartenance à la communauté que nous formons — que nous soyons enseignants, chercheurs, personnels BIATOSS et ITRF, ou étudiants — lorsque nous mettons la main à la pâte et pratiquons une informatique créatrice en créant, développant et administrant nous-mêmes nos sites web dynamiques: nous disposons des droits root.

Il existe un critère décisif d'appartenance d'une application donnée à l'informatique administrée: les utilisateurs n'ont jamais les droits root.

“root is the user name or account that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser.”

“Root privileges are the powers that the root account has on the system. The root account is the most privileged on the system and has absolute power over it (i.e., complete access to all files and commands). Among root's powers are the ability to modify the system in any way desired and to grant and revoke access permissions (i.e., the ability to read, modify and execute specific files and directories) for other users, including any of those that are by default reserved for root.”

“The use of the term root for the all-powerful administrative user may have arisen from the fact that root is the only account having write permissions (i.e., permission to modify files) in the root directory. The root directory, in turn, takes its name from the fact that the filesystems (i.e., the entire hierarchy of directories that is used to organize files) in Unix-like operating systems have been designed with a tree-like (although inverted) structure in which all directories branch off from a single directory that is analogous to the root of a tree.”
