NAME |
|
---- |
|
git-init - Create an empty Git repository or reinitialize an existing one |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
[verse] |
|
'git init' [-q | --quiet] [--bare] [--template=<template_directory>] |
|
[--separate-git-dir <git dir>] [--object-format=<format>] |
|
[-b <branch-name> | --initial-branch=<branch-name>] |
|
[--shared[=<permissions>]] [directory] |
|
|
|
|
|
DESCRIPTION |
|
----------- |
|
|
|
This command creates an empty Git repository - basically a `.git` |
|
directory with subdirectories for `objects`, `refs/heads`, |
|
`refs/tags`, and template files. An initial `HEAD` file that |
|
references the HEAD of the master branch is also created. |
|
|
|
If the `$GIT_DIR` environment variable is set then it specifies a path |
|
to use instead of `./.git` for the base of the repository. |
|
|
|
If the object storage directory is specified via the |
|
`$GIT_OBJECT_DIRECTORY` environment variable then the sha1 directories |
|
are created underneath - otherwise the default `$GIT_DIR/objects` |
|
directory is used. |
|
|
|
Running 'git init' in an existing repository is safe. It will not |
|
overwrite things that are already there. The primary reason for |
|
rerunning 'git init' is to pick up newly added templates (or to move |
|
the repository to another place if --separate-git-dir is given). |
|
|
|
OPTIONS |
|
------- |
|
|
|
-q:: |
|
--quiet:: |
|
|
|
Only print error and warning messages; all other output will be suppressed. |
|
|
|
--bare:: |
|
|
|
Create a bare repository. If `GIT_DIR` environment is not set, it is set to the |
|
current working directory. |
|
|
|
--object-format=<format>:: |
|
|
|
Specify the given object format (hash algorithm) for the repository. The valid |
|
values are 'sha1' and (if enabled) 'sha256'. 'sha1' is the default. |
|
|
|
--template=<template_directory>:: |
|
|
|
Specify the directory from which templates will be used. (See the "TEMPLATE |
|
DIRECTORY" section below.) |
|
|
|
--separate-git-dir=<git dir>:: |
|
|
|
Instead of initializing the repository as a directory to either `$GIT_DIR` or |
|
`./.git/`, create a text file there containing the path to the actual |
|
repository. This file acts as filesystem-agnostic Git symbolic link to the |
|
repository. |
|
+ |
|
If this is reinitialization, the repository will be moved to the specified path. |
|
|
|
-b <branch-name:: |
|
--initial-branch=<branch-name>:: |
|
|
|
Use the specified name for the initial branch in the newly created repository. |
|
If not specified, fall back to the default name: `master`. |
|
|
|
--shared[=(false|true|umask|group|all|world|everybody|0xxx)]:: |
|
|
|
Specify that the Git repository is to be shared amongst several users. This |
|
allows users belonging to the same group to push into that |
|
repository. When specified, the config variable "core.sharedRepository" is |
|
set so that files and directories under `$GIT_DIR` are created with the |
|
requested permissions. When not specified, Git will use permissions reported |
|
by umask(2). |
|
+ |
|
The option can have the following values, defaulting to 'group' if no value |
|
is given: |
|
+ |
|
-- |
|
'umask' (or 'false'):: |
|
|
|
Use permissions reported by umask(2). The default, when `--shared` is not |
|
specified. |
|
|
|
'group' (or 'true'):: |
|
|
|
Make the repository group-writable, (and g+sx, since the git group may be not |
|
the primary group of all users). This is used to loosen the permissions of an |
|
otherwise safe umask(2) value. Note that the umask still applies to the other |
|
permission bits (e.g. if umask is '0022', using 'group' will not remove read |
|
privileges from other (non-group) users). See '0xxx' for how to exactly specify |
|
the repository permissions. |
|
|
|
'all' (or 'world' or 'everybody'):: |
|
|
|
Same as 'group', but make the repository readable by all users. |
|
|
|
'0xxx':: |
|
|
|
'0xxx' is an octal number and each file will have mode '0xxx'. '0xxx' will |
|
override users' umask(2) value (and not only loosen permissions as 'group' and |
|
'all' does). '0640' will create a repository which is group-readable, but not |
|
group-writable or accessible to others. '0660' will create a repo that is |
|
readable and writable to the current user and group, but inaccessible to others. |
|
-- |
|
|
|
By default, the configuration flag `receive.denyNonFastForwards` is enabled |
|
in shared repositories, so that you cannot force a non fast-forwarding push |
|
into it. |
|
|
|
If you provide a 'directory', the command is run inside it. If this directory |
|
does not exist, it will be created. |
|
|
|
TEMPLATE DIRECTORY |
|
------------------ |
|
|
|
Files and directories in the template directory whose name do not start with a |
|
dot will be copied to the `$GIT_DIR` after it is created. |
|
|
|
The template directory will be one of the following (in order): |
|
|
|
- the argument given with the `--template` option; |
|
|
|
- the contents of the `$GIT_TEMPLATE_DIR` environment variable; |
|
|
|
- the `init.templateDir` configuration variable; or |
|
|
|
- the default template directory: `/usr/share/git-core/templates`. |
|
|
|
The default template directory includes some directory structure, suggested |
|
"exclude patterns" (see linkgit:gitignore[5]), and sample hook files. |
|
|
|
The sample hooks are all disabled by default. To enable one of the |
|
sample hooks rename it by removing its `.sample` suffix. |
|
|
|
See linkgit:githooks[5] for more general info on hook execution. |

|
EXAMPLES |
|
-------- |
|
|
|
Start a new Git repository for an existing code base:: |
|
+ |
|
---------------- |
|
$ cd /path/to/my/codebase |
|
$ git init <1> |
|
$ git add . <2> |
|
$ git commit <3> |
|
---------------- |
|
+ |
|
<1> Create a /path/to/my/codebase/.git directory. |
|
<2> Add all existing files to the index. |
|
<3> Record the pristine state as the first commit in the history. |
