   6git-pull - Fetch from and merge with another repository or a local branch

   9SYNOPSIS
  10--------
  11'git-pull' <options> <repository> <refspec>...
  12
  13
  14DESCRIPTION
  15-----------
  16Runs `git-fetch` with the given parameters, and calls `git-merge`
  17to merge the retrieved head(s) into the current branch.
  18With `--rebase`, calls `git-rebase` instead of `git-merge`.
  19
  20Note that you can use `.` (current directory) as the
  21<repository> to pull from the local repository -- this is useful
  22when merging local branches into the current branch.

  30
  31\--rebase::
  32        Instead of a merge, perform a rebase after fetching.  If
  33        there is a remote ref for the upstream branch, and this branch
  34        was rebased since last fetched, the rebase uses that information
  35        to avoid rebasing non-local changes. To make this the default
  36        for branch `<name>`, set configuration `branch.<name>.rebase`
  37        to `true`.
  38+
  39*NOTE:* This is a potentially _dangerous_ mode of operation.
  40It rewrites history, which does not bode well when you
  41published that history already.  Do *not* use this option
  42unless you have read linkgit:git-rebase[1] carefully.
  43
  44\--no-rebase::
  45        Override earlier \--rebase.

  55DEFAULT BEHAVIOUR
  56-----------------
  57
  58Often people use `git pull` without giving any parameter.
  59Traditionally, this has been equivalent to saying `git pull
  60origin`.  However, when configuration `branch.<name>.remote` is
  61present while on branch `<name>`, that value is used instead of
  62`origin`.
  63
  64In order to determine what URL to use to fetch from, the value
  65of the configuration `remote.<origin>.url` is consulted
  66and if there is not any such variable, the value on `URL: ` line
  67in `$GIT_DIR/remotes/<origin>` file is used.
  68
  69In order to determine what remote branches to fetch (and
  70optionally store in the tracking branches) when the command is
  71run without any refspec parameters on the command line, values
  72of the configuration variable `remote.<origin>.fetch` are
  73consulted, and if there aren't any, `$GIT_DIR/remotes/<origin>`
  74file is consulted and its `Pull: ` lines are used.
  75In addition to the refspec formats described in the OPTIONS
  76section, you can have a globbing refspec that looks like this:
  77
  78------------
  79refs/heads/*:refs/remotes/origin/*
  80------------
  81
  82A globbing refspec must have a non-empty RHS (i.e. must store
  83what were fetched in tracking branches), and its LHS and RHS
  84must end with `/*`.  The above specifies that all remote
  85branches are tracked using tracking branches in
  86`refs/remotes/origin/` hierarchy under the same name.
  87
  88The rule to determine which remote branch to merge after
  89fetching is a bit involved, in order not to break backward
  90compatibility.
  91
  92If explicit refspecs were given on the command
  93line of `git pull`, they are all merged.
  94
  95When no refspec was given on the command line, then `git pull`
  96uses the refspec from the configuration or
  97`$GIT_DIR/remotes/<origin>`.  In such cases, the following
  98rules apply:
  99
 100. If `branch.<name>.merge` configuration for the current
 101  branch `<name>` exists, that is the name of the branch at the
 102  remote site that is merged.
 103
 104. If the refspec is a globbing one, nothing is merged.
 105
 106. Otherwise the remote branch of the first refspec is merged.
 107

 109EXAMPLES
 110--------
 111
 112git pull, git pull origin::
 113        Update the remote-tracking branches for the repository
 114        you cloned from, then merge one of them into your
 115        current branch.  Normally the branch merged in is
 116        the HEAD of the remote repository, but the choice is
 117        determined by the branch.<name>.remote and
 118        branch.<name>.merge options; see linkgit:git-config[1]
 119        for details.
 120
 121git pull origin next::
 122        Merge into the current branch the remote branch `next`;
 123        leaves a copy of `next` temporarily in FETCH_HEAD, but
 124        does not update any remote-tracking branches.
 125
 126git pull . fixes enhancements::
 127        Bundle local branch `fixes` and `enhancements` on top of
 128        the current branch, making an Octopus merge.  This `git pull .`
 129        syntax is equivalent to `git merge`.
 130
 131git pull -s ours . obsolete::
 132        Merge local branch `obsolete` into the current branch,
 133        using `ours` merge strategy.
 134
 135git pull --no-commit . maint::
 136        Merge local branch `maint` into the current branch, but
 137        do not make a commit automatically.  This can be used
 138        when you want to include further changes to the merge,
 139        or want to write your own merge commit message.
 140+
 141You should refrain from abusing this option to sneak substantial
 142changes into a merge commit.  Small fixups like bumping
 143release/version name would be acceptable.
 144
 145Command line pull of multiple branches from one repository::
 146+
 147------------------------------------------------
 148$ git checkout master
 149$ git fetch origin +pu:pu maint:tmp
 150$ git pull . tmp
 151------------------------------------------------
 152+
 153This updates (or creates, as necessary) branches `pu` and `tmp`
 154in the local repository by fetching from the branches
 155(respectively) `pu` and `maint` from the remote repository.
 156+
 157The `pu` branch will be updated even if it is does not
 158fast-forward; the others will not be.
 159+
 160The final command then merges the newly fetched `tmp` into master.
 161
 162
 163If you tried a pull which resulted in a complex conflicts and
 164would want to start over, you can recover with
 165linkgit:git-reset[1].
