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]
This command creates an empty Git repository - basically a
directory with subdirectories for
refs/tags, and template files. An initial
HEAD file that
references the HEAD of the master branch is also created.
$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
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).
Only print error and warning messages; all other output will be suppressed.
Create a bare repository. If
GIT_DIRenvironment is not set, it is set to the current working directory.
Specify the given object format (hash algorithm) for the repository. The valid values are sha1 and (if enabled) sha256. sha1 is the default.
THIS OPTION IS EXPERIMENTAL! SHA-256 support is experimental and still in an early stage. A SHA-256 repository will in general not be able to share work with "regular" SHA-1 repositories. It should be assumed that, e.g., Git internal file formats in relation to SHA-256 repositories may change in backwards-incompatible ways. Only use
--object-format=sha256for testing purposes.
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/, 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>
Use the specified name for the initial branch in the newly created repository. If not specified, fall back to the default name:
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_DIRare 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
--sharedis 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 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
If you provide a directory, the command is run inside it. If this directory does not exist, it will be created.
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
the contents of the
init.templateDirconfiguration variable; or
the default template directory:
The default template directory includes some directory structure, suggested "exclude patterns" (see gitignore), and sample hook files.
The sample hooks are all disabled by default. To enable one of the
sample hooks rename it by removing its
