git-init - Create an empty git repository or reinitialize an existing
git init [-q | --quiet] [--bare] [--template=<template_directory>]
[--separate-git-dir <git dir>] [--shared[=<permissions>]] [directory]
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).
Only print error and warning messages, all other output will be
Create a bare repository. If GIT_DIR environment is not set, it is
set to the current working directory.
Specify the directory from which templates will be used. (See the
"TEMPLATE DIRECTORY" section below.)
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
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:
o umask (or false): Use permissions reported by umask(2). The
default, when --shared is not specified.
o 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.
o all (or world or everybody): Same as group, but make the
repository readable by all users.
o 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
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):
o The argument given with the --template option.
o The contents of the $GIT_TEMPLATE_DIR environment variable.
o The init.templatedir configuration variable.
o 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.
