NAME
|
|
----
|
|
git-pull - Fetch from and merge with another repository or a local branch
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git pull' <options> <repository> <refspec>...
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Runs 'git-fetch' with the given parameters, and calls 'git-merge'
|
|
to merge the retrieved head(s) into the current branch.
|
|
With `--rebase`, calls 'git-rebase' instead of 'git-merge'.
|
|
|
|
Note that you can use `.` (current directory) as the
|
|
<repository> to pull from the local repository -- this is useful
|
|
when merging local branches into the current branch.
|
|
|
|
Also note that options meant for 'git-pull' itself and underlying
|
|
'git-merge' must be given before the options meant for 'git-fetch'.
|
|
|
|
OPTIONS
|
|
-------
|
|
include::merge-options.txt[]
|
|
|
|
:git-pull: 1
|
|
|
|
--rebase::
|
|
Instead of a merge, perform a rebase after fetching. If
|
|
there is a remote ref for the upstream branch, and this branch
|
|
was rebased since last fetched, the rebase uses that information
|
|
to avoid rebasing non-local changes. To make this the default
|
|
for branch `<name>`, set configuration `branch.<name>.rebase`
|
|
to `true`.
|
|
+
|
|
[NOTE]
|
|
This is a potentially _dangerous_ mode of operation.
|
|
It rewrites history, which does not bode well when you
|
|
published that history already. Do *not* use this option
|
|
unless you have read linkgit:git-rebase[1] carefully.
|
|
|
|
--no-rebase::
|
|
Override earlier --rebase.

DEFAULT BEHAVIOUR
|
|
-----------------
|
|
|
|
Often people use `git pull` without giving any parameter.
|
|
Traditionally, this has been equivalent to saying `git pull
|
|
origin`. However, when configuration `branch.<name>.remote` is
|
|
present while on branch `<name>`, that value is used instead of
|
|
`origin`.
|
|
|
|
In order to determine what URL to use to fetch from, the value
|
|
of the configuration `remote.<origin>.url` is consulted
|
|
and if there is not any such variable, the value on `URL: ` line
|
|
in `$GIT_DIR/remotes/<origin>` file is used.
|
|
|
|
In order to determine what remote branches to fetch (and
|
|
optionally store in the tracking branches) when the command is
|
|
run without any refspec parameters on the command line, values
|
|
of the configuration variable `remote.<origin>.fetch` are
|
|
consulted, and if there aren't any, `$GIT_DIR/remotes/<origin>`
|
|
file is consulted and its `Pull: ` lines are used.
|
|
In addition to the refspec formats described in the OPTIONS
|
|
section, you can have a globbing refspec that looks like this:
|
|
|
|
------------
|
|
refs/heads/*:refs/remotes/origin/*
|
|
------------
|
|
|
|
A globbing refspec must have a non-empty RHS (i.e. must store
|
|
what were fetched in tracking branches), and its LHS and RHS
|
|
must end with `/*`. The above specifies that all remote
|
|
branches are tracked using tracking branches in
|
|
`refs/remotes/origin/` hierarchy under the same name.
|
|
|
|
The rule to determine which remote branch to merge after
|
|
fetching is a bit involved, in order not to break backward
|
|
compatibility.
|
|
|
|
If explicit refspecs were given on the command
|
|
line of `git pull`, they are all merged.
|
|
|
|
When no refspec was given on the command line, then `git pull`
|
|
uses the refspec from the configuration or
|
|
`$GIT_DIR/remotes/<origin>`. In such cases, the following
|
|
rules apply:
|
|
|
|
. If `branch.<name>.merge` configuration for the current
|
|
branch `<name>` exists, that is the name of the branch at the
|
|
remote site that is merged.
|
|
|
|
. If the refspec is a globbing one, nothing is merged.
|
|
|
|
. Otherwise the remote branch of the first refspec is merged.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
* Update the remote-tracking branches for the repository
|
|
you cloned from, then merge one of them into your
|
|
current branch:
|
|
+
|
|
------------------------------------------------
|
|
$ git pull, git pull origin
|
|
------------------------------------------------
|
|
+
|
|
Normally the branch merged in is the HEAD of the remote repository,
|
|
but the choice is determined by the branch.<name>.remote and
|
|
branch.<name>.merge options; see linkgit:git-config[1] for details.
|
|
|
|
* Merge into the current branch the remote branch `next`:
|
|
+
|
|
------------------------------------------------
|
|
$ git pull origin next
|
|
------------------------------------------------
|
|
+
|
|
This leaves a copy of `next` temporarily in FETCH_HEAD, but
|
|
does not update any remote-tracking branches.
|
|
|
|
* Bundle local branch `fixes` and `enhancements` on top of
|
|
the current branch, making an Octopus merge:
|
|
+
|
|
------------------------------------------------
|
|
$ git pull . fixes enhancements
|
|
------------------------------------------------
|
|
+
|
|
This `git pull .` syntax is equivalent to `git merge`.
|
|
|
|
* Merge local branch `obsolete` into the current branch, using `ours`
|
|
merge strategy:
|
|
+
|
|
------------------------------------------------
|
|
$ git pull -s ours . obsolete
|
|
------------------------------------------------
|
|
|
|
* Merge local branch `maint` into the current branch, but do not make
|
|
a commit automatically:
|
|
+
|
|
------------------------------------------------
|
|
$ git pull --no-commit . maint
|
|
------------------------------------------------
|
|
+
|
|
This can be used when you want to include further changes to the
|
|
merge, or want to write your own merge commit message.
|
|
+
|
|
You should refrain from abusing this option to sneak substantial
|
|
changes into a merge commit. Small fixups like bumping
|
|
release/version name would be acceptable.
|
|
|
|
* Command line pull of multiple branches from one repository:
|
|
+
|
|
------------------------------------------------
|
|
$ git checkout master
|
|
$ git fetch origin +pu:pu maint:tmp
|
|
$ git pull . tmp
|
|
------------------------------------------------
|
|
+
|
|
This updates (or creates, as necessary) branches `pu` and `tmp` in
|
|
the local repository by fetching from the branches (respectively)
|
|
`pu` and `maint` from the remote repository.
|
|
+
|
|
The `pu` branch will be updated even if it is does not fast-forward;
|
|
the others will not be.
|
|
+
|
|
The final command then merges the newly fetched `tmp` into master.
|
|
|
|
|
|
If you tried a pull which resulted in a complex conflicts and
|
|
would want to start over, you can recover with 'git-reset'.
