6 git-init - Create an empty git repository or reinitialize an existing one
11 'git init' [-q | --quiet] [--bare] [--template=<template_directory>] [--shared[=<permissions>]] [directory]
22 Only print error and warning messages, all other output will be suppressed.
26 Create a bare repository. If GIT_DIR environment is not set, it is set to the
27 current working directory.
29 --template=<template_directory>::
31 Provide the directory from which templates will be used. The default template
32 directory is `/usr/share/git-core/templates`.
34 When specified, `<template_directory>` is used as the source of the template
35 files rather than the default. The template files include some directory
36 structure, some suggested "exclude patterns", and copies of non-executing
37 "hook" files. The suggested patterns and hook files are all modifiable and
40 --shared[={false|true|umask|group|all|world|everybody|0xxx}]::
42 Specify that the git repository is to be shared amongst several users. This
43 allows users belonging to the same group to push into that
44 repository. When specified, the config variable "core.sharedRepository" is
45 set so that files and directories under `$GIT_DIR` are created with the
46 requested permissions. When not specified, git will use permissions reported
49 The option can have the following values, defaulting to 'group' if no value
52 - 'umask' (or 'false'): Use permissions reported by umask(2). The default,
53 when `--shared` is not specified.
55 - 'group' (or 'true'): Make the repository group-writable, (and g+sx, since
56 the git group may be not the primary group of all users).
57 This is used to loosen the permissions of an otherwise safe umask(2) value.
58 Note that the umask still applies to the other permission bits (e.g. if
59 umask is '0022', using 'group' will not remove read privileges from other
60 (non-group) users). See '0xxx' for how to exactly specify the repository
63 - 'all' (or 'world' or 'everybody'): Same as 'group', but make the repository
64 readable by all users.
66 - '0xxx': '0xxx' is an octal number and each file will have mode '0xxx'.
67 '0xxx' will override users' umask(2) value (and not only loosen permissions
68 as 'group' and 'all' does). '0640' will create a repository which is
69 group-readable, but not group-writable or accessible to others. '0660' will
70 create a repo that is readable and writable to the current user and group,
71 but inaccessible to others.
73 By default, the configuration flag receive.denyNonFastForwards is enabled
74 in shared repositories, so that you cannot force a non fast-forwarding push
77 If you name a (possibly non-existent) directory at the end of the command
78 line, the command is run inside the directory (possibly after creating it).
85 This command creates an empty git repository - basically a `.git` directory
86 with subdirectories for `objects`, `refs/heads`, `refs/tags`, and
88 An initial `HEAD` file that references the HEAD of the master branch
91 If the `$GIT_DIR` environment variable is set then it specifies a path
92 to use instead of `./.git` for the base of the repository.
94 If the object storage directory is specified via the `$GIT_OBJECT_DIRECTORY`
95 environment variable then the sha1 directories are created underneath -
96 otherwise the default `$GIT_DIR/objects` directory is used.
98 Running 'git init' in an existing repository is safe. It will not overwrite
99 things that are already there. The primary reason for rerunning 'git init'
100 is to pick up newly added templates.
102 Note that 'git init' is the same as 'git init-db'. The command
103 was primarily meant to initialize the object database, but over
104 time it has become responsible for setting up the other aspects
105 of the repository, such as installing the default hooks and
106 setting the configuration variables. The old name is retained
107 for backward compatibility reasons.
113 Start a new git repository for an existing code base::
116 $ cd /path/to/my/codebase
121 <1> prepare /path/to/my/codebase/.git directory
122 <2> add all existing file to the index
