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 branch without any
|
|
commits will be created (see the `--initial-branch` option below
|
|
for its name).
|
|
|
|
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 `$GIT_DIR/objects`
|
|
directory is used.
|
|
|
|
Running `git init` in an existing repository is safe. It will not
|
|
overwrite things that are already there. The primary reason for
|
|
rerunning `git init` is to pick up newly added templates (or to move
|
|
the repository to another place if `--separate-git-dir` is given).
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
`-q`::
|
|
`--quiet`::
|
|
|
|
Only print error and warning messages; all other output will be suppressed.
|
|
|
|
`--bare`::
|
|
|
|
Create a bare repository. If `GIT_DIR` environment is not set, it is set to the
|
|
current working directory.
|
|
|
|
++--object-format=++__<format>__::
|
|
|
|
Specify the given object _<format>_ (hash algorithm) for the repository. The valid
|
|
values are `sha1` and (if enabled) `sha256`. `sha1` is the default.
|
|
+
|
|
include::object-format-disclaimer.txt[]
|
|
|
|
++--ref-format=++__<format>__::
|
|
|
|
Specify the given ref storage _<format>_ for the repository. The valid values are:
|
|
+
|
|
include::ref-storage-format.txt[]
|
|
|
|
++--template=++__<template-directory>__::
|
|
|
|
Specify the directory from which templates will be used. (See the "TEMPLATE
|
|
DIRECTORY" section below.)
|
|
|
|
++--separate-git-dir=++__<git-dir>__::
|
|
|
|
Instead of initializing the repository as a directory to either `$GIT_DIR` or
|
|
`./.git/`, create a text file there containing the path to the actual
|
|
repository. This file acts as a filesystem-agnostic Git symbolic link to the
|
|
repository.
|
|
+
|
|
If this is a reinitialization, the repository will be moved to the specified path.
|
|
|
|
`-b` _<branch-name>_::
|
|
++--initial-branch=++__<branch-name>__::
|
|
|
|
Use _<branch-name>_ for the initial branch in the newly created
|
|
repository. If not specified, fall back to the default name (currently
|
|
`master`, but this is subject to change in the future; the name can be
|
|
customized via the `init.defaultBranch` configuration variable).
|
|
|
|
++--shared++[++=++(`false`|`true`|`umask`|`group`|`all`|`world`|`everybody`|_<perm>_)]::
|
|
|
|
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`::
|
|
`false`::
|
|
|
|
Use permissions reported by `umask`(2). The default, when `--shared` is not
|
|
specified.
|
|
|
|
`group`::
|
|
`true`::
|
|
|
|
Make the repository group-writable, (and `g+sx`, since the git group may not be
|
|
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`::
|
|
`world`::
|
|
`everybody`::
|
|
|
|
Same as `group`, but make the repository readable by all users.
|
|
|
|
_<perm>_::
|
|
|
|
_<perm>_ is a 3-digit octal number prefixed with `0` and each file
|
|
will have mode _<perm>_. _<perm>_ will override users' `umask`(2)
|
|
value (and not only loosen permissions as `group` and `all`
|
|
do). `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 (directories and executable files get their
|
|
`x` bit from the `r` bit for corresponding classes of users).
|
|
--
|
|
|
|
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.
