Understanding git-init
The git-init command is the primary method used to create a new git repository. Executing this command creates a .git subdirectory in the current working directory, which contains all of the necessary metadata for the new repository. This metadata includes subdirectories for objects, refs, and template files. A HEAD file is also created, which points to the currently checked-out branching reference.
Core Functionality
When a developer runs git-init, they are effectively placing a project under version-control. Unlike other systems that require a server-side setup, git allows for local initialization, making it a distributed system. If the directory already contains a .git directory, running git-init again will not overwrite existing data; instead, it reinitializes the repository, which can be useful for picking up newly added templates or moving the repository to a new location.
Common Options and Configurations
The command supports several flags to customize the initialization process. The --bare flag is used to create a remote-repository that does not have a working directory, meaning files cannot be edited directly in that location. This is standard for central servers where developers push their code. Additionally, the --initial-branch (or -b) option allows users to specify the name of the initial branch, overriding the default set in the global git-config. According to the official Git documentation, initializing a repository is the first step before using git-add or git-commit.
