Change the documentation so that: * We don't talk about "little scripts". Hooks can be as big as you want, and don't have to be scripts, just call them "programs". * We note that we change the working directory before a hook is called, nothing documented this explicitly, but the current behavior is predictable. It helps a lot to know what directory these hooks will be executed from. * We don't make claims about the example hooks which may not be true depending on the configuration of 'init.templateDir'. Clarify that we're talking about the default settings of git-init in those cases, and move some of this documentation into git-init's documentation about the default templates. * We briefly note in the intro that hooks can get their arguments in various different ways, and that how exactly is described below for each hook.

NAME

|
----
|
|
git-init - Create an empty Git repository or reinitialize an existing one
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git init' [-q | --quiet] [--bare] [--template=<template_directory>]
|
|
[--separate-git-dir <git dir>]
|
|
[--shared[=<permissions>]] [directory]
|
|
|
|
|
|
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 `$GIT_DIR/objects`
|
|
directory is used.
|
|
|
|
Running 'git init' in an existing repository is safe. It will not
|
|
overwrite things that are already there. The primary reason for
|
|
rerunning 'git init' is to pick up newly added templates (or to move
|
|
the repository to another place if --separate-git-dir is given).
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--
|
|
|
|
-q::
|
|
--quiet::
|
|
|
|
Only print error and warning messages; all other output will be suppressed.
|
|
|
|
--bare::
|
|
|
|
Create a bare repository. If GIT_DIR environment is not set, it is set to the
|
|
current working directory.
|
|
|
|
--template=<template_directory>::
|
|
|
|
Specify the directory from which templates will be used. (See the "TEMPLATE
|
|
DIRECTORY" section below.)
|
|
|
|
--separate-git-dir=<git dir>::
|
|
|
|
Instead of initializing the repository as a directory to either `$GIT_DIR` or
|
|
`./.git/`, create a text file there containing the path to the actual
|
|
repository. This file acts as filesystem-agnostic Git symbolic link to the
|
|
repository.
|
|
+
|
|
If this is reinitialization, the repository will be moved to the specified path.
|
|
|
|
--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). 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'::
|
|
|
|
'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 provide a 'directory', the command is run inside it. If this directory
|
|
does not exist, it will be created.
|
|
|

|
|
TEMPLATE DIRECTORY
|
|
------------------
|
|
|
|
The template directory contains files and directories that 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.

EXAMPLES
|
|
--------
|
|
|
|
Start a new Git repository for an existing code base::
|
|
+
|
|
----------------
|
|
$ cd /path/to/my/codebase
|
|
$ git init <1>
|
|
$ git add . <2>
|
|
$ git commit <3>
|
|
----------------
|
|
+
|
|
<1> Create a /path/to/my/codebase/.git directory.
|
|
<2> Add all existing files to the index.
|
|
<3> Record the pristine state as the first commit in the history.
