скачать объекты и ссылки из другого репозитория (Download objects and refs from another repository)
Описание (Description)
Fetch branches and/or tags (collectively, "refs") from one or
more other repositories, along with the objects necessary to
complete their histories. Remote-tracking branches are updated
(see the description of <refspec> below for ways to control this
behavior).
By default, any tag that points into the histories being fetched
is also fetched; the effect is to fetch tags that point at
branches that you are interested in. This default behavior can be
changed by using the --tags or --no-tags options or by
configuring remote.<name>.tagOpt. By using a refspec that fetches
tags explicitly, you can fetch tags that do not point into
branches you are interested in as well.
git fetch can fetch from either a single named repository or URL,
or from several repositories at once if <group> is given and
there is a remotes.<group> entry in the configuration file. (See
git-config(1)).
When no remote is specified, by default the origin remote will be
used, unless there's an upstream branch configured for the
current branch.
The names of refs that are fetched, together with the object
names they point at, are written to .git/FETCH_HEAD. This
information may be used by scripts or other git commands, such as
git-pull(1).
