    git-fetch

    
    
    

    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 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 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.
    
               disables this automatic tag following.
    
           -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.
    
           -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
    
                   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/
    
           For local respositories, 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 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.
    
    
               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.
