git init --shared=0xxx, where '0xxx' is an octal number, will create a repository with file modes set to '0xxx'. Users with a safe umask value (0077) can use this option to force file modes. For example, '0640' is a group-readable but not group-writable regardless of user's umask value. Values compatible with old Git versions are written as they were before, for compatibility reasons. That is, "1" for "group" and "2" for "everybody". "git config core.sharedRepository 0xxx" is also handled.

NAME
|
|
----
|
|
git-init - Create an empty git repository or reinitialize an existing one
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-init' [-q | --quiet] [--template=<template_directory>] [--shared[=<permissions>]]
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--
|
|
|
|
-q, \--quiet::
|
|
|
|
Only print error and warning messages, all other output will be suppressed.
|
|
|
|
--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
