Explanation
update-alternatives creates, removes, maintains too displays data nearly the symbolic links comprising the alternatives system. The alternatives organisation is a reimplementation of the Debian alternatives system. It was rewritten primarily to take away the dependence on perl; it is intended to endure a driblet inwards replacement for Debian’s update-dependencies script. This human being page is a slightly modified version of the human being page from the Debian project.
It is possible for several programs fulfilling the same or like functions to endure installed on a unmarried organisation at the same time. For example, many systems bring several text editors installed at once. This gives choice to the users of a system, allowing each to usage a unlike editor, if desired, merely makes it hard for a programme to brand a proficient choice of editor to invoke if the user has non specified a item preference.
The alternatives organisation aims to solve this problem. Influenza A virus subtype H5N1 generic advert inwards the filesystem is shared yesteryear all files providing interchangeable functionality. The alternatives organisation too the organisation administrator together determine which actual file is referenced yesteryear this generic name. For example, if the text editors ed too nvi are both installed on the system, the alternatives organisation volition drive the generic advert /usr/bin/editor to refer to /usr/bin/nvi yesteryear default. The organisation administrator tin override this too drive it to refer to /usr/bin/ed instead, too the alternatives organisation volition non alter this setting until explicitly requested to practice so.
The generic advert is non a straightaway symbolic link to the selected alternative. Instead, it is a symbolic link to a advert inwards the alternatives directory, which inwards plow is a symbolic link to the actual file referenced. This is done hence that the organisation administrator’s changes tin endure confined inside the /etc directory: the FHS (q.v.) gives reasons why this is a Good Thing.
When each bundle providing a file amongst a item functionality is installed, changed or removed, alternatives is called to update data nearly that file inwards the alternatives system. alternatives is normally called from the %post or %pre scripts inwards RPM packages.
It is oftentimes useful for a expose of alternatives to endure synchronised, hence that they are changed equally a group; for example, when several versions of the half-dozen editor are installed, the human being page referenced yesteryear /usr/share/man/man1/vi.1 should gibe to the executable referenced yesteryear /usr/bin/vi. alternatives handles this yesteryear way of master copy too slave links; when the master copy is changed, whatever associated slaves are changed too. Influenza A virus subtype H5N1 master copy link too its associated slaves brand upward a link group.
Each link grouping is, at whatever given time, inwards ane of ii modes: automatic or manual. When a grouping is inwards automatic mode, the alternatives organisation volition automatically decide, equally packages are installed too removed, whether too how to update the links. In manual mode, the alternatives organisation volition non modify the links; it volition teach out all the decisions to the organisation administrator.
Link groups are inwards automatic trend when they are rootage introduced to the system. If the organisation administrator makes changes to the system’s automatic settings, this volition endure noticed the adjacent fourth dimension alternatives is run on the changed link’s group, too the grouping volition automatically endure switched to manual mode.
Each alternative has a priority associated amongst it. When a link grouping is inwards automatic mode, the alternatives pointed to yesteryear members of the grouping volition endure those which bring the highest priority.
When using the –config option, alternatives volition listing all of the choices for the link grouping of which given advert is the master copy link. You volition too hence endure prompted for which of the choices to usage for the link group. Once yous brand a change, the link grouping volition no longer endure inwards machine mode. You volition involve to usage the –auto choice inwards club to supply to the automatic state. Read the consummate human being page here
