6 git-init - Create an empty git repository or reinitialize an existing one
12 'git init' [-q | --quiet] [--bare] [--template=<template_directory>]
13 [--separate-git-dir <git dir>]
14 [--shared[=<permissions>]] [directory]
20 This command creates an empty git repository - basically a `.git`
21 directory with subdirectories for `objects`, `refs/heads`,
22 `refs/tags`, and template files. An initial `HEAD` file that
23 references the HEAD of the master branch is also created.
25 If the `$GIT_DIR` environment variable is set then it specifies a path
26 to use instead of `./.git` for the base of the repository.
28 If the object storage directory is specified via the
29 `$GIT_OBJECT_DIRECTORY` environment variable then the sha1 directories
30 are created underneath - otherwise the default `$GIT_DIR/objects`
33 Running 'git init' in an existing repository is safe. It will not
34 overwrite things that are already there. The primary reason for
35 rerunning 'git init' is to pick up newly added templates (or to move
36 the repository to another place if --separate-git-dir is given).
46 Only print error and warning messages, all other output will be suppressed.
50 Create a bare repository. If GIT_DIR environment is not set, it is set to the
51 current working directory.
53 --template=<template_directory>::
55 Specify the directory from which templates will be used. (See the "TEMPLATE
56 DIRECTORY" section below.)
58 --separate-git-dir=<git dir>::
60 Instead of initializing the repository where it is supposed to be,
61 place a filesytem-agnostic git symbolic link there, pointing to the
62 specified git path, and initialize a git repository at the path. The
63 result is git repository can be separated from working tree. If this
64 is reinitialization, the repository will be moved to the specified
67 --shared[=(false|true|umask|group|all|world|everybody|0xxx)]::
69 Specify that the git repository is to be shared amongst several users. This
70 allows users belonging to the same group to push into that
71 repository. When specified, the config variable "core.sharedRepository" is
72 set so that files and directories under `$GIT_DIR` are created with the
73 requested permissions. When not specified, git will use permissions reported
76 The option can have the following values, defaulting to 'group' if no value
79 - 'umask' (or 'false'): Use permissions reported by umask(2). The default,
80 when `--shared` is not specified.
82 - 'group' (or 'true'): Make the repository group-writable, (and g+sx, since
83 the git group may be not the primary group of all users).
84 This is used to loosen the permissions of an otherwise safe umask(2) value.
85 Note that the umask still applies to the other permission bits (e.g. if
86 umask is '0022', using 'group' will not remove read privileges from other
87 (non-group) users). See '0xxx' for how to exactly specify the repository
90 - 'all' (or 'world' or 'everybody'): Same as 'group', but make the repository
91 readable by all users.
93 - '0xxx': '0xxx' is an octal number and each file will have mode '0xxx'.
94 '0xxx' will override users' umask(2) value (and not only loosen permissions
95 as 'group' and 'all' does). '0640' will create a repository which is
96 group-readable, but not group-writable or accessible to others. '0660' will
97 create a repo that is readable and writable to the current user and group,
98 but inaccessible to others.
100 By default, the configuration flag receive.denyNonFastForwards is enabled
101 in shared repositories, so that you cannot force a non fast-forwarding push
104 If you name a (possibly non-existent) directory at the end of the command
105 line, the command is run inside the directory (possibly after creating it).
113 The template directory contains files and directories that will be copied to
114 the `$GIT_DIR` after it is created.
116 The template directory used will (in order):
118 - The argument given with the `--template` option.
120 - The contents of the `$GIT_TEMPLATE_DIR` environment variable.
122 - The `init.templatedir` configuration variable.
124 - The default template directory: `/usr/share/git-core/templates`.
126 The default template directory includes some directory structure, some
127 suggested "exclude patterns", and copies of sample "hook" files.
128 The suggested patterns and hook files are all modifiable and extensible.
