# git-init(1) Manual Page

## NAME

git-init - Create an empty git repository or reinitialize an existing one

## SYNOPSIS

git init [-q | --quiet] [--bare] [--template=<template_directory>] [--shared[=<permissions>]]

## 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>

  Provide the directory from which templates will be used. The default template directory is `/usr/share/git-core/templates`.

  When specified, `<template_directory>` is used as the source of the template files rather than the default. The template files include some directory structure, some suggested "exclude patterns", and copies of non-executing "hook" files. The suggested patterns and hook files are all modifiable and extensible.

--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).

  - 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 Any option except umask can be set using this option. 0xxx will override users umask(2) value, and thus, users with a safe umask (0077) can use this option. 0640 will create a repository which is group-readable but not writable. 0660 is equivalent to group.

    By default, the configuration flag receive.denyNonFastForwards is enabled in shared repositories, so that you cannot force a non fast-forwarding push into it.

## 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.

Note that git-init is the same as git-init-db. The command was primarily meant to initialize the object database, but over time it has become responsible for setting up the other aspects of the repository, such as installing the default hooks and setting the configuration variables. The old name is retained for backward compatibility reasons.

## 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
