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>]
|
|
[--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 `$GIT_DIR/objects`
|
|
directory is used.
|
|
|
|
Running 'git init' in an existing repository is safe. It will not
|
|
overwrite things that are already there. The primary reason for
|
|
rerunning 'git init' is to pick up newly added templates (or to move
|
|
the repository to another place if --separate-git-dir is given).
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--
|
|
|
|
-q::
|
|
--quiet::
|
|
|
|
Only print error and warning messages, all other output will be suppressed.
|
|
|
|
--bare::
|
|
|
|
Create a bare repository. If GIT_DIR environment is not set, it is set to the
|
|
current working directory.
|
|
|
|
--template=<template_directory>::
|
|
|
|
Specify the directory from which templates will be used. (See the "TEMPLATE
|
|
DIRECTORY" section below.)
|
|
|
|
--separate-git-dir=<git dir>::
|
|
|
|
Instead of initializing the repository where it is supposed to be,
|
|
place a filesytem-agnostic git symbolic link there, pointing to the
|
|
specified git path, and initialize a git repository at the path. The
|
|
result is git repository can be separated from working tree. If this
|
|
is reinitialization, the repository will be moved to the specified
|
|
path.
|
|
|
|
--shared[=(false|true|umask|group|all|world|everybody|0xxx)]::
|
|
|
|
Specify that the git repository is to be shared amongst several users. This
|
|
allows users belonging to the same group to push into that
|
|
repository. When specified, the config variable "core.sharedRepository" is
|
|
set so that files and directories under `$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 name a (possibly non-existent) directory at the end of the command
|
|
line, the command is run inside the directory (possibly after creating it).

TEMPLATE DIRECTORY
|
|
------------------
|
|
|
|
The template directory contains files and directories that will be copied to
|
|
the `$GIT_DIR` after it is created.
|
|
|
|
The template directory used will (in order):
|
|
|
|
- The argument given with the `--template` option.
|
|
|
|
- The contents of the `$GIT_TEMPLATE_DIR` environment variable.
|
|
|
|
- The `init.templatedir` configuration variable.
|
|
|
|
- The default template directory: `/usr/share/git-core/templates`.
|
|
|
|
The default template directory includes some directory structure, some
|
|
suggested "exclude patterns", and copies of sample "hook" files.
|
|
The suggested patterns and hook files are all modifiable and extensible.

EXAMPLES
|
|
--------
|
|
|
|
Start a new git repository for an existing code base::
|
|
+
|
|
----------------
|
|
$ cd /path/to/my/codebase
|
|
$ git init <1>
|
|
$ git add . <2>
|
|
----------------
|
|
+
|
|
<1> prepare /path/to/my/codebase/.git directory
|
|
<2> add all existing file to the index
