GIT-FETCH(1)                      Git Manual                      GIT-FETCH(1)



NAME
       git-fetch - Download objects and refs from another repository

SYNOPSIS
       git fetch [<options>] [<repository> [<refspec>...]]
       git fetch [<options>] <group>
       git fetch --multiple [<options>] [(<repository> | <group>)...]
       git fetch --all [<options>]


DESCRIPTION
       Fetches named heads or tags from one or more other repositories, along with the objects necessary to complete
       them.

       The ref names and their object names of fetched refs are stored in .git/FETCH_HEAD. This information is left
       for a later merge operation done by git merge.

       When <refspec> stores the fetched result in remote-tracking branches, the tags that point at these branches are
       automatically followed. This is done by first fetching from the remote using the given <refspec>s, and if the
       repository has objects that are pointed by remote tags that it does not yet have, then fetch those missing
       tags. If the other end has tags that point at branches you are not interested in, you will not get them.

       git fetch can fetch from either a single named repository, or from several repositories at once if <group> is
       given and there is a remotes.<group> entry in the configuration file. (See git-config(1)).

OPTIONS
       --all
           Fetch all remotes.

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

       --depth=<depth>
           Deepen the history of a shallow repository created by git clone with --depth=<depth> option (see git-
           clone(1)) by the specified number of commits.

       --dry-run
           Show what would be done, without making any changes.

       -f, --force
           When git fetch is used with <rbranch>:<lbranch> refspec, it refuses to update the local branch <lbranch>
           unless the remote branch <rbranch> it fetches is a descendant of <lbranch>. This option overrides that
           check.

       -k, --keep
           Keep downloaded pack.

       --multiple
           Allow several <repository> and <group> arguments to be specified. No <refspec>s may be specified.

       -p, --prune
           After fetching, remove any remote-tracking branches which no longer exist on the remote.

       -n, --no-tags
           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. The default behavior for a remote may be
           specified with the remote.<name>.tagopt setting. See git-config(1).

       -t, --tags
           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. The default behavior for a remote may be
           specified with the remote.<name>.tagopt setting. See git-config(1).

       --recurse-submodules[=yes|on-demand|no]
           This option controls if and under what conditions new commits of populated submodules should be fetched
           too. It can be used as a boolean option to completely disable recursion when set to no or to
           unconditionally recurse into all populated submodules when set to yes, which is the default when this
           option is used without any value. Use on-demand to only recurse into a populated submodule when the
           superproject retrieves a commit that updates the submodule's reference to a commit that isn't already in
           the local submodule clone.

       --no-recurse-submodules
           Disable recursive fetching of submodules (this has the same effect as using the --recurse-submodules=no
           option).

       --submodule-prefix=<path>
           Prepend <path> to paths printed in informative messages such as "Fetching submodule foo". This option is
           used internally when recursing over submodules.

       --recurse-submodules-default=[yes|on-demand]
           This option is used internally to temporarily provide a non-negative default value for the
           --recurse-submodules option. All other methods of configuring fetch's submodule recursion (such as settings
           in gitmodules(5) and git-config(1)) override this option, as does specifying --[no-]recurse-submodules
           directly.

       -u, --update-head-ok
           By default git fetch refuses to update the head which corresponds to the current branch. This flag disables
           the check. This is purely for the internal use for git pull to communicate with git fetch, and unless you
           are implementing your own Porcelain you are not supposed to use it.

       --upload-pack <upload-pack>
           When given, and the repository to fetch from is handled by git fetch-pack, --exec=<upload-pack> is passed
           to the command to specify non-default path for the command run on the other end.

       -q, --quiet
           Pass --quiet to git-fetch-pack and silence any other internally used git commands. Progress is not reported
           to the standard error stream.

       -v, --verbose
           Be verbose.

       --progress
           Progress status is reported on the standard error stream by default when it is attached to a terminal,
           unless -q is specified. This flag forces progress status even if the standard error stream is not directed
           to a terminal.

       <repository>
           The "remote" repository that is the source of a fetch or pull operation. This parameter can be either a URL
           (see the section GIT URLS below) or the name of a remote (see the section REMOTES below).

       <group>
           A name referring to a list of repositories as the value of remotes.<group> in the configuration file. (See
           git-config(1)).

       <refspec>
           The format of a <refspec> parameter is an optional plus +, followed by the source ref <src>, followed by a
           colon :, followed by the destination ref <dst>.

           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>. If the optional plus + is used, the local ref is updated even if it does
           not result in a fast-forward update.

               Note
               If the remote branch from which you want to pull is modified in non-linear ways such as being rewound
               and rebased frequently, then a pull will attempt a merge with an older version of itself, likely
               conflict, and fail. It is under these conditions that you would want to use the + 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.

               Note
               You never do your own development on branches that appear on the right hand side of a <refspec> colon
               on Pull: lines; they are to be updated by git fetch. If you intend to do development derived from a
               remote branch B, have a Pull: line to track it (i.e.  Pull: B:remote-B), and have a separate branch
               my-B to do your development on top of it. The latter is created by git branch my-B remote-B (or its
               equivalent git checkout -b my-B remote-B). Run git fetch to keep track of the progress of the remote
               side, and when you see something new on the remote branch, merge it into your development branch with
               git pull . remote-B, while you are on my-B branch.

               Note
               There is a difference between listing multiple <refspec> directly on git pull command line and having
               multiple Pull: <refspec> lines for a <repository> and running git pull command without any explicit
               <refspec> parameters. <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 git pull run without any explicit <refspec> parameter takes default <refspec>s
               from Pull: 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 is often useful.
           Some short-cut notations are also supported.

           ?    tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>; it requests fetching everything up to the
               given tag.

           ?   A parameter <ref> without a colon is equivalent to <ref>: when pulling/fetching, so it merges <ref>
               into the current branch without storing the remote branch anywhere locally

GIT URLS
       In general, URLs contain information about the transport protocol, the address of the remote server, and the
       path to the repository. Depending on the transport protocol, some of this information may be absent.

       Git natively supports ssh, git, http, https, ftp, ftps, and rsync protocols. The following syntaxes may be used
       with them:

       ?   ssh://[user@]host.xz[:port]/path/to/repo.git/

       ?   git://host.xz[:port]/path/to/repo.git/

       ?   http[s]://host.xz[:port]/path/to/repo.git/

       ?   ftp[s]://host.xz[:port]/path/to/repo.git/

       ?   rsync://host.xz/path/to/repo.git/

       An alternative scp-like syntax may also be used with the ssh protocol:

       ?   [user@]host.xz:path/to/repo.git/

       The ssh and git protocols additionally support ~username expansion:

       ?   ssh://[user@]host.xz[:port]/~[user]/path/to/repo.git/

       ?   git://host.xz[:port]/~[user]/path/to/repo.git/

       ?   [user@]host.xz:/~[user]/path/to/repo.git/

       For local repositories, also supported by git natively, the following syntaxes may be used:

       ?   /path/to/repo.git/

       ?    file:///path/to/repo.git/

       These two syntaxes are mostly equivalent, except when cloning, when the former implies --local option. See git-
       clone(1) for details.

       When git doesn't know how to handle a certain transport protocol, it attempts to use the remote-<transport>
       remote helper, if one exists. To explicitly request a remote helper, the following syntax may be used:

       ?   <transport>::<address>

       where <address> may be a path, a server and path, or an arbitrary URL-like string recognized by the specific
       remote helper being invoked. See git-remote-helpers(1) for details.

       If there are a large number of similarly-named remote repositories and you want to use a different format for
       them (such that the URLs you use will be rewritten into URLs that work), you can create a configuration section
       of the form:

                   [url "<actual url base>"]
                           insteadOf = <other url base>


       For example, with this:

                   [url "git://git.host.xz/"]
                           insteadOf = host.xz:/path/to/
                           insteadOf = work:


       a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be rewritten in any context that takes a
       URL to be "git://git.host.xz/repo.git".

       If you want to rewrite URLs for push only, you can create a configuration section of the form:

                   [url "<actual url base>"]
                           pushInsteadOf = <other url base>


       For example, with this:

                   [url "ssh://example.org/"]
                           pushInsteadOf = git://example.org/


       a URL like "git://example.org/path/to/repo.git" will be rewritten to "ssh://example.org/path/to/repo.git" for
       pushes, but pulls will still use the original URL.

REMOTES
       The name of one of the following can be used instead of a URL as <repository> argument:

       ?   a remote in the git configuration file: $GIT_DIR/config,

       ?   a file in the $GIT_DIR/remotes directory, or

       ?   a file in the $GIT_DIR/branches directory.

       All of these also allow you to omit the refspec from the command line because they each contain a refspec which
       git will use by default.

   Named remote in configuration file
       You can choose to provide the name of a remote which you had previously configured using git-remote(1), git-
       config(1) or even by a manual edit to the $GIT_DIR/config file. The URL of this remote will be used to access
       the repository. The refspec of this remote will be used by default when you do not provide a refspec on the
       command line. The entry in the config file would appear like this:

                   [remote "<name>"]
                           url = <url>
                           pushurl = <pushurl>
                           push = <refspec>
                           fetch = <refspec>


       The <pushurl> is used for pushes only. It is optional and defaults to <url>.

   Named file in $GIT_DIR/remotes
       You can choose to provide the name of a file in $GIT_DIR/remotes. The URL in this file will be used to access
       the repository. The refspec in this file will be used as default when you do not provide a refspec on the
       command line. This file should have the following format:

                   URL: one of the above URL format
                   Push: <refspec>
                   Pull: <refspec>


       Push: lines are used by git push and Pull: lines are used by git pull and git fetch. Multiple Push: and Pull:
       lines may be specified for additional branch mappings.

   Named file in $GIT_DIR/branches
       You can choose to provide the name of a file in $GIT_DIR/branches. The URL in this file will be used to access
       the repository. This file should have the following format:

                   <url>#<head>


       <url> is required; #<head> is optional.

       Depending on the operation, git will use one of the following refspecs, if you don't provide one on the command
       line. <branch> is the name of this file in $GIT_DIR/branches and <head> defaults to master.

       git fetch uses:

                   refs/heads/<head>:refs/heads/<branch>


       git push uses:

                   HEAD:refs/heads/<head>


EXAMPLES
       ?   Update the remote-tracking branches:

               $ git fetch origin

           The above command copies all branches from the remote refs/heads/ namespace and stores them to the local
           refs/remotes/origin/ namespace, unless the branch.<name>.fetch option is used to specify a non-default
           refspec.

       ?   Using refspecs explicitly:

               $ git fetch origin +pu:pu maint: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, because it is prefixed with a plus sign;
           tmp will not be.

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.
