$ git reset --hard HEAD^ HEAD is now at b679adb add initial file1.txt $ cat file1.txt hello
branch
par defaut, une seule branche *master*
$ git branch * master
creation d'un branche *option1* , ne modifie en rien les fichiers (pas de recopie)
$ git branch option1 $ git branch * master option1 $ ls -al total 52 -rw-r--r-- 1 login mci 6 9 avril 10:11 file1.txt drwxr-xr-x 8 login mci 4096 9 avril 10:11 .git
passage sur la branche option1 , git checkout est utilisé pour changer de branche mais aussi pour restaurer un fichier tel qu’il était lors du dernier commit. La commande a donc un double usage.
$ git checkout option1 Switched to branch 'option1' $ git branch master * option1 $ ls -al total 52 -rw-r--r-- 1 login mci 6 9 avril 10:11 file1.txt drwxr-xr-x 8 login mci 4096 9 avril 10:28 .git
