Git Init Command

git-init(1) =========== NAME ---- git-init - Create an empty Git repository or reinitialize an existing one SYNOPSIS -------- [synopsis] git init [-q | --quiet] [--bare] [--template=<template-directory>] [--separate-git-dir <git-dir>] [--object-format=<format>] [--ref-format=<format>] [-b <branch-name> | --initial-branch=<branch-name>] [--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 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 `$GIT_DIR/objects` directory is used. Running `git init` in an existing repository is safe. It will not overwrite things that are already there. The primary reason for rerunning `git init` is to pick up newly added templates (or to move the repository to another place if `--separate-git-dir` is given). OPTIONS ------- `-q`:: `--quiet`:: Only print error and warning messages; all other output will be suppressed. `--bare`:: Create a bare repository. If `GIT_DIR` environment is not set, it is set to the current working directory. `--object-format=<format>`:: Specify the given object _<format>_ (hash algorithm) for the repository. The valid values are `sha1` and (if enabled) `sha256`. `sha1` is the default. + include::object-format-disclaimer.adoc[] `--ref-format=<format>`:: Specify the given ref storage _<format>_ for the repository. The valid values are: + include::ref-storage-format.adoc[] `--template=<template-directory>`:: Specify the directory from which templates will be used. (See the "TEMPLATE DIRECTORY" section below.) `--separate-git-dir=<git-dir>`:: Instead of initializing the repository as a directory to either `$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

The git init command creates an empty Git repository or reinitializes an existing one, setting up the necessary directories and files for Git to function, with various options for customization and configuration.
