A3.1 Git Commands - Setup and Config

Throughout the book we have introduced dozens of Git commands and have tried hard to introduce them within something of a narrative, adding more commands to the story slowly. However, this leaves us with examples of usage of the commands somewhat scattered throughout the whole book.

Setup and Config

There are two commands that are used quite a lot, from the first invocations of Git to common every day tweaking and referencing, the config and help commands.

git config

Git has a default way of doing hundreds of things. For a lot of these things, you can tell Git to default to doing them a different way, or set your preferences. This invovles everything from telling Git what your name is to specific terminal color preferences or what editor you use. There are several files this command will read from and write to so you can set values globally or down to specific repositories.

The git config command has been used in nearly every chapter of the book.

In “Paramétrage à la première utilisation de Git” we used it to specify our name, email address and editor preference before we even got started using Git.

In “Les alias Git” we showed how you could use it to create shorthand commands that expand to long option sequences so you don’t have to type them every time.

In “Rebaser (Rebasing)” we used it to make --rebase the default when you run git pull.

In “Stockage des identifiants” we used it to set up a default store for your HTTP passwords.

In <<_keyword_expansion> we showed how to set up smudge and clean filters on content coming in and out of Git.

Finally, basically the entirety of “Configuration de Git” is dedicated to the command.

git help

The git help command is used to show you all the documentation shipped with Git about any command. While we’re giving a rough overview of most of the more popular ones in this appendix, for a full listing of all of the possible options and flags for every command, you can always run git help <command>.

We introduced the git help command in “Obtenir de l’aide” and showed you how to use it to find more information about the git shell in “Mise en place du serveur”.
