Working with Well-Known Repositories - Git Recipes - page 23

If you want to display the contents of a .git directory you can use the following com-
mands:

$ cd git-recipes/02-03/
$ cd .git
$ ls -l

The last command will print the files and directories shown in Figure 2-6 . The role
of every item is briefly described in Table 2-2 . The complete descriptions are included
in the recipes dealing with the specific details of git.

Table 2-2 . The contents of a .git directory

Directory/file Description

Directory contains scripts that can be automatically executed by git when some
events occur; for example, before each commit and after each commit.

hooks/

Directory contains a single file named exclude , which can be used to exclude
files from a repository. Unlike the .gitignore file, this file is not shared by
others.

info/

logs/ Directory contains logs of local changes made to the repository.

This is the database that contains all the information about files, directories, revi-
sions, and tags.

objects/

refs/ This is where git stores the information about branches and lightweight tags.

This is the local configuration file containing the options that will be applied to
this repository only.

config

plication distributed with git.
