'git remote' is meant for managing remotes and 'git fetch' is meant for actually fetching data from remote repositories. Therefore, it is not logical that you must use 'git remote update' to fetch from more than one repository at once. Add the --all option to 'git fetch', to tell it to attempt to fetch from all remotes. Also, if --all is not given, the <repository> argument is allowed to be the name of a group, to allow fetching from all repositories in the group. Other options except -v and -q are silently ignored.

<repository>::
|
|
The "remote" repository that is the source of a fetch
|
|
or pull operation. This parameter can be either a URL
|
|
(see the section <<URLS,GIT URLS>> below) or the name
|
|
of a remote (see the section <<REMOTES,REMOTES>> below).
|
|
|
|
ifndef::git-pull[]
|
|
<group>::
|
|
A name referring to a list of repositories as the value
|
|
of remotes.<group> in the configuration file.
|
|
(See linkgit:git-config[1]).
|
|
endif::git-pull[]
|
|
|
|
<refspec>::
|
|
The format of a <refspec> parameter is an optional plus
|
|
`{plus}`, followed by the source ref <src>, followed
|
|
by a colon `:`, followed by the destination ref <dst>.
|
|
+
|
|
The remote ref that matches <src>
|
|
is fetched, and if <dst> is not empty string, the local
|
|
ref that matches it is fast forwarded using <src>.
|
|
If the optional plus `+` is used, the local ref
|
|
is updated even if it does not result in a fast forward
|
|
update.
|
|
+
|
|
[NOTE]
|
|
If the remote branch from which you want to pull is
|
|
modified in non-linear ways such as being rewound and
|
|
rebased frequently, then a pull will attempt a merge with
|
|
an older version of itself, likely conflict, and fail.
|
|
It is under these conditions that you would want to use
|
|
the `+` sign to indicate non-fast-forward updates will
|
|
be needed. There is currently no easy way to determine
|
|
or declare that a branch will be made available in a
|
|
repository with this behavior; the pulling user simply
|
|
must know this is the expected usage pattern for a branch.
|
|
+
|
|
[NOTE]
|
|
You never do your own development on branches that appear
|
|
on the right hand side of a <refspec> colon on `Pull:` lines;
|
|
they are to be updated by 'git-fetch'. If you intend to do
|
|
development derived from a remote branch `B`, have a `Pull:`
|
|
line to track it (i.e. `Pull: B:remote-B`), and have a separate
|
|
branch `my-B` to do your development on top of it. The latter
|
|
is created by `git branch my-B remote-B` (or its equivalent `git
|
|
checkout -b my-B remote-B`). Run `git fetch` to keep track of
|
|
the progress of the remote side, and when you see something new
|
|
on the remote branch, merge it into your development branch with
|
|
`git pull . remote-B`, while you are on `my-B` branch.
|
|
+
|
|
[NOTE]
|
|
There is a difference between listing multiple <refspec>
|
|
directly on 'git-pull' command line and having multiple
|
|
`Pull:` <refspec> lines for a <repository> and running
|
|
'git-pull' command without any explicit <refspec> parameters.
|
|
<refspec> listed explicitly on the command line are always
|
|
merged into the current branch after fetching. In other words,
|
|
if you list more than one remote refs, you would be making
|
|
an Octopus. While 'git-pull' run without any explicit <refspec>
|
|
parameter takes default <refspec>s from `Pull:` lines, it
|
|
merges only the first <refspec> found into the current branch,
|
|
after fetching all the remote refs. This is because making an
|
|
Octopus from remote refs is rarely done, while keeping track
|
|
of multiple remote heads in one-go by fetching more than one
|
|
is often useful.
|
|
+
|
|
Some short-cut notations are also supported.
|
|
+
|
|
* `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`;
|
|
it requests fetching everything up to the given tag.
|
|
* A parameter <ref> without a colon is equivalent to
|
|
<ref>: when pulling/fetching, so it merges <ref> into the current
|
|
branch without storing the remote branch anywhere locally
