<h2>NAME</h2> | |
<div class="sectionbody"> | |
<p>git-pull - | |
Fetch from and merge with another repository or a local branch | |
</p> | |
</div> | |
</div> | |
<h2>SYNOPSIS</h2> | |
<div class="sectionbody"> | |
<div class="para"><p><em>git pull</em> <options> <repository> <refspec>…</p></div> | |
</div> | |
<h2 id="_description">DESCRIPTION</h2> | |
<div class="sectionbody"> | |
<div class="para"><p>Runs <em>git-fetch</em> with the given parameters, and calls <em>git-merge</em> | |
to merge the retrieved head(s) into the current branch. | |
With <tt>--rebase</tt>, calls <em>git-rebase</em> instead of <em>git-merge</em>.</p></div> | |
<div class="para"><p>Note that you can use <tt>.</tt> (current directory) as the | |
<repository> to pull from the local repository — this is useful | |
when merging local branches into the current branch.</p></div> | |
<div class="para"><p>Also note that options meant for <em>git-pull</em> itself and underlying | |
<em>git-merge</em> must be given before the options meant for <em>git-fetch</em>.</p></div> | |
</div> | |
<h2 id="_options">OPTIONS</h2> | |
<div class="sectionbody"> | |
<div class="vlist"><dl> | |
<dt> | |
-q | |
</dt> | |
<dt> | |
--quiet | |

<dt> | |
-v | |
</dt> | |
<dt> | |
--verbose | |
</dt> | |
<dd> | |
<p> | |
Be verbose. | |
</p> | |
</dd> | |
<dt> | |
--stat | |
</dt> | |
<dd> | |
<p> | |
Show a diffstat at the end of the merge. The diffstat is also | |
controlled by the configuration option merge.stat. | |
</p> | |
</dd> | |
<dt> | |
-n | |
</dt> | |
<dt> | |
--no-stat | |
</dt> | |
<dd> | |
<p> | |
Do not show a diffstat at the end of the merge. | |
</p> | |
</dd> | |
<dt> | |
--summary | |
</dt> | |
<dt> | |
--no-summary | |
</dt> | |
<dd> | |
<p> | |
Synonyms to --stat and --no-stat; these are deprecated and will be | |
removed in the future. | |
</p> | |
</dd> | |
<dt> | |
--log | |
</dt> | |
<dd> | |
<p> | |
In addition to branch names, populate the log message with | |
one-line descriptions from the actual commits that are being | |
merged. | |
</p> | |
</dd> | |
<dt> | |
--no-log | |
</dt> | |
<dd> | |
<p> | |
Do not list one-line descriptions from the actual commits being | |
merged. | |
</p> | |
</dd> | |
<dt> | |
--no-commit | |
</dt> | |
<dd> | |
<p> | |
Perform the merge but pretend the merge failed and do | |
not autocommit, to give the user a chance to inspect and | |
further tweak the merge result before committing. | |
</p> | |
</dd> | |
<dt> | |
--commit | |
</dt> | |
<dd> | |
<p> | |
Perform the merge and commit the result. This option can | |
be used to override --no-commit. | |
</p> | |
</dd> | |
<dt> | |
--squash | |
</dt> | |
<dd> | |
<p> | |
Produce the working tree and index state as if a real | |
merge happened, but do not actually make a commit or | |
move the <tt>HEAD</tt>, nor record <tt>$GIT_DIR/MERGE_HEAD</tt> to | |
cause the next <tt>git commit</tt> command to create a merge | |
commit. This allows you to create a single commit on | |
top of the current branch whose effect is the same as | |
merging another branch (or more in case of an octopus). | |
</p> | |
</dd> | |
<dt> | |
--no-squash | |
</dt> | |
<dd> | |
<p> | |
Perform the merge and commit the result. This option can | |
be used to override --squash. | |
</p> | |
</dd> | |
<dt> | |
--no-ff | |
</dt> | |
<dd> | |
<p> | |
Generate a merge commit even if the merge resolved as a | |
fast-forward. | |
</p> | |
</dd> | |
<dt> | |
--ff | |
</dt> | |
<dd> | |
<p> | |
Do not generate a merge commit if the merge resolved as | |
a fast-forward, only update the branch pointer. This is | |
the default behavior of git-merge. | |
</p> | |
</dd> | |
<dt> | |
-s <strategy> | |
</dt> | |
<dt> | |
--strategy=<strategy> | |
</dt> | |
<dd> | |
<p> | |
Use the given merge strategy; can be supplied more than | |
once to specify them in the order they should be tried. | |
If there is no <tt>-s</tt> option, a built-in list of strategies | |
is used instead (<em>git-merge-recursive</em> when merging a single | |
head, <em>git-merge-octopus</em> otherwise). | |
</p> | |
</dd> | |
</dl></div> | |
<div class="vlist"><dl> | |
<dt> | |
--rebase | |
</dt> | |
<dd> | |
<p> | |
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 <tt><name></tt>, set configuration <tt>branch.<name>.rebase</tt> | |
to <tt>true</tt>. | |

Pass --quiet to git-fetch-pack and silence any other internally | |
used programs. | |

Append ref names and object names of fetched refs to the | |
existing contents of <tt>.git/FETCH_HEAD</tt>. Without this | |
option old data in <tt>.git/FETCH_HEAD</tt> will be overwritten. | |
</p> | |
</dd> | |
<dt> | |
--upload-pack <upload-pack> | |
</dt> | |
<dd> | |
<p> | |
When given, and the repository to fetch from is handled | |
by <em>git-fetch-pack</em>, <em>--exec=<upload-pack></em> is passed to | |
the command to specify non-default path for the command | |
run on the other end. | |
</p> | |
</dd> | |
<dt> | |
-f | |
</dt> | |
<dt> | |
--force | |
</dt> | |
<dd> | |
<p> | |
When <em>git-fetch</em> is used with <tt><rbranch>:<lbranch></tt> | |
refspec, it refuses to update the local branch | |
<tt><lbranch></tt> unless the remote branch <tt><rbranch></tt> it | |
fetches is a descendant of <tt><lbranch></tt>. This option | |
overrides that check. | |
</p> | |
</dd> | |
<dt> | |
--no-tags | |
</dt> | |
<dd> | |
<p> | |
By default, tags that point at objects that are downloaded | |
from the remote repository are fetched and stored locally. | |
This option disables this automatic tag following. | |
</p> | |
</dd> | |
<dt> | |
-t | |
</dt> | |
<dt> | |
--tags | |
</dt> | |
<dd> | |
<p> | |
Most of the tags are fetched automatically as branch | |
heads are downloaded, but tags that do not point at | |
objects reachable from the branch heads that are being | |
tracked will not be fetched by this mechanism. This | |
flag lets all tags and their associated objects be | |
downloaded. | |
</p> | |
</dd> | |
<dt> | |
-k | |
</dt> | |
<dt> | |
--keep | |
</dt> | |
<dd> | |
<p> | |
Keep downloaded pack. | |
</p> | |
</dd> | |
<dt> | |
-u | |
</dt> | |
<dt> | |
--update-head-ok | |
</dt> | |
<dd> | |
<p> | |
By default <em>git-fetch</em> refuses to update the head which | |
corresponds to the current branch. This flag disables the | |
check. This is purely for the internal use for <em>git-pull</em> | |
to communicate with <em>git-fetch</em>, and unless you are | |
implementing your own Porcelain you are not supposed to | |
use it. | |
</p> | |
</dd> | |
<dt> | |
--depth=<depth> | |
</dt> | |
<dd> | |
<p> | |
Deepen the history of a <em>shallow</em> repository created by | |
<tt>git clone</tt> with <tt>--depth=<depth></tt> option (see <a href="git-clone.html">git-clone(1)</a>) | |
by the specified number of commits. | |
</p> | |
</dd> | |
<dt> | |
<repository> | |
</dt> | |
<dd> | |
<p> | |
The "remote" repository that is the source of a fetch | |
or pull operation. This parameter can be either a URL | |
(see the section <a href="#URLS">GIT URLS</a> below) or the name | |
of a remote (see the section <a href="#REMOTES">REMOTES</a> below). | |
</p> | |
</dd> | |
<dt> | |
<refspec> | |
</dt> | |
<dd> | |
<p> | |
The canonical format of a <refspec> parameter is | |
<tt>+?<src>:<dst></tt>; that is, an optional plus <tt>+</tt>, followed | |
by the source ref, followed by a colon <tt>:</tt>, followed by | |
the destination ref. | |
</p> | |
<div class="para"><p>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>. | |
Again, if the optional plus <tt>+</tt> is used, the local ref | |
is updated even if it does not result in a fast forward | |
update.</p></div> | |

<td class="content">If the remote branch from which you want to pull is | |
modified in non-linear ways such as being rewound and | |

an older version of itself, likely conflict, and fail. | |
It is under these conditions that you would want to use | |
the <tt>+</tt> 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.</td> | |

line to track it (i.e. <tt>Pull: B:remote-B</tt>), and have a separate | |
branch <tt>my-B</tt> to do your development on top of it. The latter | |
is created by <tt>git branch my-B remote-B</tt> (or its equivalent <tt>git | |
checkout -b my-B remote-B</tt>). Run <tt>git fetch</tt> to keep track of | |
the progress of the remote side, and when you see something new | |

<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 <em>git-pull</em> run without any explicit <refspec> | |
parameter takes default <refspec>s from <tt>Pull:</tt> 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 | |

<div class="sectionbody"> | |
<div class="vlist"><dl> | |
<dt> | |
resolve | |
</dt> | |
<dd> | |
<p> | |
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. | |
</p> | |
</dd> | |
<dt> | |
recursive | |
</dt> | |
<dd> | |
<p> | |
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 ancestors 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. This is the default merge strategy when | |
pulling or merging one branch. | |
</p> | |
</dd> | |
<dt> | |
octopus | |
</dt> | |
<dd> | |
<p> | |
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 or merging more than one branches. | |
</p> | |
</dd> | |
<dt> | |
ours | |
</dt> | |
<dd> | |
<p> | |
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. | |
</p> | |
</dd> | |
<dt> | |
subtree | |
</dt> | |
<dd> | |
<p> | |
This is a modified recursive strategy. When merging trees A and | |
B, if B corresponds to a subtree of A, B is first adjusted to | |
match the tree structure of A, instead of reading the trees at | |
the same level. This adjustment is also done to the common | |
ancestor tree. | |

<h2 id="_default_behaviour">DEFAULT BEHAVIOUR</h2> | |
<div class="sectionbody"> | |
<div class="para"><p>Often people use <tt>git pull</tt> without giving any parameter. | |
Traditionally, this has been equivalent to saying <tt>git pull | |
origin</tt>. However, when configuration <tt>branch.<name>.remote</tt> is | |
present while on branch <tt><name></tt>, that value is used instead of | |
<tt>origin</tt>.</p></div> | |
<div class="para"><p>In order to determine what URL to use to fetch from, the value | |
of the configuration <tt>remote.<origin>.url</tt> is consulted | |
and if there is not any such variable, the value on <tt>URL: </tt> line | |
in <tt>$GIT_DIR/remotes/<origin></tt> file is used.</p></div> | |
<div class="para"><p>In order to determine what remote branches to fetch (and | |
optionally store in the tracking branches) when the command is | |
run without any refspec parameters on the command line, values | |
of the configuration variable <tt>remote.<origin>.fetch</tt> are | |
consulted, and if there aren't any, <tt>$GIT_DIR/remotes/<origin></tt> | |
file is consulted and its <tt>Pull: </tt> lines are used. | |
In addition to the refspec formats described in the OPTIONS | |
section, you can have a globbing refspec that looks like this:</p></div> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>refs/heads/*:refs/remotes/origin/*</tt></pre> | |
</div></div> | |
<div class="para"><p>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 <tt>/*</tt>. The above specifies that all remote | |
branches are tracked using tracking branches in | |
<tt>refs/remotes/origin/</tt> hierarchy under the same name.</p></div> | |
<div class="para"><p>The rule to determine which remote branch to merge after | |
fetching is a bit involved, in order not to break backward | |
compatibility.</p></div> | |
<div class="para"><p>If explicit refspecs were given on the command | |
line of <tt>git pull</tt>, they are all merged.</p></div> | |
<div class="para"><p>When no refspec was given on the command line, then <tt>git pull</tt> | |
uses the refspec from the configuration or | |
<tt>$GIT_DIR/remotes/<origin></tt>. In such cases, the following | |
rules apply:</p></div> | |
<div class="olist"><ol> | |
<li> | |
<p> | |
If <tt>branch.<name>.merge</tt> configuration for the current | |
branch <tt><name></tt> exists, that is the name of the branch at the | |
remote site that is merged. | |
</p> | |
</li> | |
<li> | |
<p> | |
If the refspec is a globbing one, nothing is merged. | |
</p> | |
</li> | |
<li> | |
<p> | |
Otherwise the remote branch of the first refspec is merged. | |
