NAME

-git-pull - Pull and merge from another repository.
+git-pull - Pull and merge from another repository or a local branch
SYNOPSIS
DESCRIPTION
-----------
-Runs 'git-fetch' with the given parameters.
+Runs `git-fetch` with the given parameters, and calls `git-merge`
+to merge the retrieved head(s) into the current branch.
-When only one ref is downloaded, runs 'git resolve' to merge it
-into the local HEAD. Otherwise uses 'git octopus' to merge them
-into the local HEAD.
-
-Note that you can use '.' (current directory) as the
+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.

--a, \--append::
- Append ref names and object names of fetched refs to the
- existing contents of $GIT_DIR/FETCH_HEAD. Without this
- option old data in $GIT_DIR/FETCH_HEAD will be overwritten.

-MERGE STRATEGIES
-----------------
-
-resolve::
- This can only resolve two heads (i.e. the current branch
- and another branch you pulled from) using 3-way merge
- algorithm. It tries to carefully detect criss-cross
- merge ambiguities and is considered generally safe and
- fast. This is the default merge strategy when pulling
- one branch.
-
-recursive::
- This can only resolve two heads using 3-way merge
- algorithm. When there are more than one common
- ancestors that can be used for 3-way merge, it creates a
- merged tree of the common ancestores and uses that as
- the reference tree for the 3-way merge. This has been
- reported to result in fewer merge conflicts without
- causing mis-merges by tests done on actual merge commits
- taken from Linux 2.6 kernel development history.
- Additionally this can detect and handle merges involving
- renames.
-
-octopus::
- This resolves more than two-head case, but refuses to do
- complex merge that needs manual resolution. It is
- primarily meant to be used for bundling topic branch
- heads together. This is the default merge strategy when
- pulling more than one branch.
-
-ours::
- This resolves any number of heads, but the result of the
- merge is always the current branch head. It is meant to
- be used to supersede old development history of side
- branches.

EXAMPLES
--------
git pull, git pull origin::
- Fetch the default head from the repository you cloned
- from and merge it into your current branch.
-
-git pull -s ours . obsolete::
- Merge local branch `obsolete` into the current branch,
- using `ours` merge strategy.
+ Update the remote-tracking branches for the repository
+ you cloned from, then merge one of them into your
+ current branch. 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 gitlink:git-repo-config[1]
+ for details.
+
+git pull origin next::
+ Merge into the current branch the remote branch `next`;
+ leaves a copy of `next` temporarily in FETCH_HEAD, but
+ does not update any remote-tracking branches.
git pull . fixes enhancements::
Bundle local branch `fixes` and `enhancements` on top of
the current branch, making an Octopus merge.
+git pull -s ours . obsolete::
+ Merge local branch `obsolete` into the current branch,
+ using `ours` merge strategy.
+
git pull --no-commit . maint::
Merge local branch `maint` into the current branch, but
do not make a commit automatically. This can be used
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
+gitlink:git-reset[1].
