SYNOPSIS
--------
-'git pull' <options> <repository> <refspec>...
+[verse]
+'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.
+Incorporates changes from a remote repository into the current
+branch. In its default mode, `git pull` is shorthand for
+`git fetch` followed by `git merge FETCH_HEAD`.
-Also note that options meant for 'git-pull' itself and underlying
-'git-merge' must be given before the options meant for 'git-fetch'.
+More precisely, 'git pull' runs 'git fetch' with the given
+parameters and calls 'git merge' to merge the retrieved branch
+heads into the current branch.
+With `--rebase`, it runs 'git rebase' instead of 'git merge'.
+
+<repository> should be the name of a remote repository as
+passed to linkgit:git-fetch[1]. <refspec> can name an
+arbitrary remote ref (for example, the name of a tag) or even
+a collection of refs with corresponding remote-tracking branches
+(e.g., refs/heads/{asterisk}:refs/remotes/origin/{asterisk}),
+but usually it is the name of a branch in the remote repository.
+
+Default values for <repository> and <branch> are read from the
+"remote" and "merge" configuration for the current branch
+as set by linkgit:git-branch[1] `--track`.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+ A---B---C master on origin
+ /
+ D---E---F---G master
+------------
+
+Then "`git pull`" will fetch and replay the changes from the remote
+`master` branch since it diverged from the local `master` (i.e., `E`)
+until its current commit (`C`) on top of `master` and record the
+result in a new commit along with the names of the two parent commits
+and a log message from the user describing the changes.
+
+------------
+ A---B---C remotes/origin/master
+ / \
+ D---E---F---G---H master
+------------
+
+See linkgit:git-merge[1] for details, including how conflicts
+are presented and handled.
+
+In git 1.7.0 or later, to cancel a conflicting merge, use
+`git reset --merge`. *Warning*: In older versions of git, running 'git pull'
+with uncommitted changes is discouraged: while possible, it leaves you
+in a state that may be hard to back out of in the case of a conflict.
+
+If any of the remote changes overlap with local uncommitted changes,
+the merge will be automatically cancelled and the work tree untouched.
+It is generally best to get any local changes in working order before
+pulling or stash them away with linkgit:git-stash[1].
OPTIONS
-------
+
+Options meant for 'git pull' itself and the underlying 'git merge'
+must be given before the options meant for 'git fetch'.
+
+-q::
+--quiet::
+ This is passed to both underlying git-fetch to squelch reporting of
+ during transfer, and underlying git-merge to squelch output during
+ merging.
+
+-v::
+--verbose::
+ Pass --verbose to git-fetch and git-merge.
+
+--[no-]recurse-submodules[=yes|on-demand|no]::
+ This option controls if new commits of all populated submodules should
+ be fetched too (see linkgit:git-config[1] and linkgit:gitmodules[5]).
+ That might be necessary to get the data needed for merging submodule
+ commits, a feature git learned in 1.7.3. Notice that the result of a
+ merge will not be checked out in the submodule, "git submodule update"
+ has to be called afterwards to bring the work tree up to date with the
+ merge result.

: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`.
+ Rebase the current branch on top of the upstream branch after
+ fetching. If there is a remote-tracking branch corresponding to
+ the upstream branch and the upstream branch was rebased since last
+ fetched, the rebase uses that information to avoid rebasing
+ non-local changes.
++
+See `pull.rebase`, `branch.<name>.rebase` and `branch.autosetuprebase` in
+linkgit:git-config[1] if you want to make `git pull` always use
+`{litdd}rebase` instead of merging.
+
[NOTE]
This is a potentially _dangerous_ mode of operation.
--no-rebase::
Override earlier --rebase.
+Options related to fetching

in `$GIT_DIR/remotes/<origin>` file is used.
In order to determine what remote branches to fetch (and
-optionally store in the tracking branches) when the command is
+optionally store in the remote-tracking branches) when the command is
run without any refspec parameters on the command line, values
of the configuration variable `remote.<origin>.fetch` are
consulted, and if there aren't any, `$GIT_DIR/remotes/<origin>`
------------
A globbing refspec must have a non-empty RHS (i.e. must store
-what were fetched in tracking branches), and its LHS and RHS
+what were fetched in remote-tracking branches), and its LHS and RHS
must end with `/*`. The above specifies that all remote
-branches are tracked using tracking branches in
+branches are tracked using remote-tracking branches in
`refs/remotes/origin/` hierarchy under the same name.
The rule to determine which remote branch to merge after
------------------------------------------------
+
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:
+does not update any remote-tracking branches. Using remote-tracking
+branches, the same can be done by invoking fetch and merge:
+
------------------------------------------------
-$ git pull . fixes enhancements
+$ git fetch origin
+$ git merge origin/next
------------------------------------------------
-+
-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'.
+would want to start over, you can recover with 'git reset'.
+BUGS
+----
+Using --recurse-submodules can only fetch new commits in already checked
+out submodules right now. When e.g. upstream added a new submodule in the
+just fetched commits of the superproject the submodule itself can not be
+fetched, making it impossible to check out that submodule later without
+having to do a fetch again. This is expected to be fixed in a future git
+version.
