   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.
  23
  24Also note that options meant for `git-pull` itself and underlying
  25`git-merge` must be given before the options meant for `git-fetch`.

  27OPTIONS

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

  57DEFAULT BEHAVIOUR
  58-----------------
  59
  60Often people use `git pull` without giving any parameter.
  61Traditionally, this has been equivalent to saying `git pull
  62origin`.  However, when configuration `branch.<name>.remote` is
  63present while on branch `<name>`, that value is used instead of
  64`origin`.
  65
  66In order to determine what URL to use to fetch from, the value
  67of the configuration `remote.<origin>.url` is consulted
  68and if there is not any such variable, the value on `URL: ` line
  69in `$GIT_DIR/remotes/<origin>` file is used.
  70
  71In order to determine what remote branches to fetch (and
  72optionally store in the tracking branches) when the command is
  73run without any refspec parameters on the command line, values
  74of the configuration variable `remote.<origin>.fetch` are
  75consulted, and if there aren't any, `$GIT_DIR/remotes/<origin>`
  76file is consulted and its `Pull: ` lines are used.
  77In addition to the refspec formats described in the OPTIONS
  78section, you can have a globbing refspec that looks like this:
  79
  80------------
  81refs/heads/*:refs/remotes/origin/*
  82------------
  83
  84A globbing refspec must have a non-empty RHS (i.e. must store
  85what were fetched in tracking branches), and its LHS and RHS
  86must end with `/*`.  The above specifies that all remote
  87branches are tracked using tracking branches in
  88`refs/remotes/origin/` hierarchy under the same name.
  89
  90The rule to determine which remote branch to merge after
  91fetching is a bit involved, in order not to break backward
  92compatibility.
  93
  94If explicit refspecs were given on the command
  95line of `git pull`, they are all merged.
  96
  97When no refspec was given on the command line, then `git pull`
  98uses the refspec from the configuration or
  99`$GIT_DIR/remotes/<origin>`.  In such cases, the following
 100rules apply:
 101
 102. If `branch.<name>.merge` configuration for the current
 103  branch `<name>` exists, that is the name of the branch at the
 104  remote site that is merged.
 105
 106. If the refspec is a globbing one, nothing is merged.
 107
 108. Otherwise the remote branch of the first refspec is merged.
 109
 110
 111EXAMPLES
 112--------
 113
 114* Update the remote-tracking branches for the repository
 115  you cloned from, then merge one of them into your
 116  current branch:
 117+
 118------------------------------------------------
 119$ git pull, git pull origin
 120------------------------------------------------
 121+
 122Normally the branch merged in is the HEAD of the remote repository,
 123but the choice is determined by the branch.<name>.remote and
 124branch.<name>.merge options; see linkgit:git-config[1] for details.
 125
 126* Merge into the current branch the remote branch `next`:
 127+
 128------------------------------------------------
 129$ git pull origin next
 130------------------------------------------------
 131+
 132This leaves a copy of `next` temporarily in FETCH_HEAD, but
 133does not update any remote-tracking branches.
 134
 135* Bundle local branch `fixes` and `enhancements` on top of
 136  the current branch, making an Octopus merge:
 137+
 138------------------------------------------------
 139$ git pull . fixes enhancements
 140------------------------------------------------
 141+
 142This `git pull .` syntax is equivalent to `git merge`.
 143
 144* Merge local branch `obsolete` into the current branch, using `ours`
 145  merge strategy:
 146+
 147------------------------------------------------
 148$ git pull -s ours . obsolete
 149------------------------------------------------
 150
 151* Merge local branch `maint` into the current branch, but do not make
 152  a commit automatically:
 153+
 154------------------------------------------------
 155$ git pull --no-commit . maint
 156------------------------------------------------
 157+
 158This can be used when you want to include further changes to the
 159merge, or want to write your own merge commit message.
 160+
 161You should refrain from abusing this option to sneak substantial
 162changes into a merge commit.  Small fixups like bumping
 163release/version name would be acceptable.
 164
 165* Command line pull of multiple branches from one repository:
 166+
 167------------------------------------------------
 168$ git checkout master
 169$ git fetch origin +pu:pu maint:tmp
 170$ git pull . tmp
 171------------------------------------------------
 172+
 173This updates (or creates, as necessary) branches `pu` and `tmp` in
 174the local repository by fetching from the branches (respectively)
 175`pu` and `maint` from the remote repository.
 176+
 177The `pu` branch will be updated even if it is does not fast-forward;
 178the others will not be.
 179+
 180The final command then merges the newly fetched `tmp` into master.
 181
 182
 183If you tried a pull which resulted in a complex conflicts and
 184would want to start over, you can recover with
 185linkgit:git-reset[1].
