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 `$GIT_DIR/objects` +directory is used. + +Running 'git init' in an existing repository is safe. It will not +overwrite things that are already there. The primary reason for +rerunning 'git init' is to pick up newly added templates (or to move +the repository to another place if --separate-git-dir is given). + +OPTIONS +------- + +-- + +-q:: +--quiet:: + +Only print error and warning messages, all other output will be suppressed. + +--bare:: + +Create a bare repository. If GIT_DIR environment is not set, it is set to the +current working directory. + +--template=<template_directory>:: + +Specify the directory from which templates will be used. (See the "TEMPLATE +DIRECTORY" section below.) + +--separate-git-dir=<git dir>:: + +Instead of initializing the repository where it is supposed to be, +place a filesytem-agnostic Git symbolic link there, pointing to the +specified path, and initialize a Git repository at the path. The +result is Git repository can be separated from working tree. If this +is reinitialization, the repository will be moved to the specified +path. + +--shared[=(false|true|umask|group|all|world|everybody|0xxx)]:: + +Specify that the Git repository is to be shared amongst several users. This +allows users belonging to the same group to push into that +repository. When specified, the config variable "core.sharedRepository" is +set so that files and directories under `$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 name a (possibly non-existent) directory at the end of the command +line, the command is run inside the directory (possibly after creating it). + +-- + + +TEMPLATE DIRECTORY +------------------ + +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. + +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 + +GIT +--- +Part of the linkgit:git[1] suite |
