GIT-INIT(1)                       Git Manual                       GIT-INIT(1)

       git-init - Create an empty git repository or reinitialize an existing one

       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).

       -q, --quiet
           Only print error and warning messages, all other output will be suppressed.

           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.)

       --separate-git-dir=<git dir>
           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 specified path.

           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

       ?    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 name a (possibly non-existent) directory at the end of the command line, the command is run inside the
       directory (possibly after creating it).

       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):

       ?   The argument given with the --template option.

       ?   The contents of the $GIT_TEMPLATE_DIR environment variable.

       ?   The init.templatedir configuration variable.

       ?   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.

       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
