Отчет по лабораторной работе №2 “Система контроля версий Git”
Выполнил: Антонов Д.А.
Группа: А-03-23
Проверил: Козлюк Д.А.
Примечание: работа выполнялась на OS X.
1. Cоздал на рабочем столе каталог lab02 и запустил в нем Git Bash
dmitrijantonov@MacBook-Air-Dmitrij ~ % cd desktop
dmitrijantonov@MacBook-Air-Dmitrij desktop % cd lab02
2. Просмотрел файлы в рабочем каталоге можно командой “ls” – пусто:
dmitrijantonov@MacBook-Air-Dmitrij lab02 % ls
3.Создал каталоги Алисы и Боба, создал каталог “project”,изучил команду “cd” в процессе:
dmitrijantonov@MacBook-Air-Dmitrij lab02 % mkdir alice
dmitrijantonov@MacBook-Air-Dmitrij lab02 % mkdir bob
dmitrijantonov@MacBook-Air-Dmitrij lab02 % cd alice
dmitrijantonov@MacBook-Air-Dmitrij alice % mkdir project
dmitrijantonov@MacBook-Air-Dmitrij alice % cd project
dmitrijantonov@MacBook-Air-Dmitrij project % cd ..
dmitrijantonov@MacBook-Air-Dmitrij alice % cd project
4.Инициализировал репозитарий:
dmitrijantonov@MacBook-Air-Dmitrij project % git init
Initialized empty Git repository in /Users/dmitrijantonov/Desktop/lab02/alice/project/.git/
5. Смотрю имя ветки git. По умолчанию git создал ветку под названием main
dmitrijantonov@MacBook-Air-Dmitrij project % git status
On branch main
6. Посмотрл папку, где git хранит свою данные
dmitrijantonov@MacBook-Air-Dmitrij project % ls -A
.git
7. Настроил репозитарий Алисы, чтобы коммиты были от ее имени:
dmitrijantonov@MacBook-Air-Dmitrij project % git config user.name 'Alice (AntonovDA)'
dmitrijantonov@MacBook-Air-Dmitrij project % git config user.email 'AntonovDAn@mpei.ru'
8. Заносим под git файл main2.cpp (набор изменений, который войдет в коммит)
dmitrijantonov@MacBook-Air-Dmitrij project % git add main2.cpp
9. Проверил Состояние репозитория ( появился отслеживаемый файл )
dmitrijantonov@MacBook-Air-Dmitrij project % git status
On branch main
No commits yet
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: main2.cpp
Untracked files:
(use "git add <file>..." to include in what will be committed)
.DS_Store
main2
main2.dSYM/
10. Выполнил коммит с файлом main2.cpp и коротким сообщением
dmitrijantonov@MacBook-Air-Dmitrij project % git commit -m 'code: заготовка программы'
[main (root-commit) 9896924] code: заготовка программы

[main bad78bc] build: add projecct file
1 file changed, 9 insertions(+)
create mode 100644 project.cbp
11. Сделал изменения в main2.cpp. Когда добавлялся новый файл, он помечался как: new file: main2.cpp. А измененный - modified: main2.cpp
dmitrijantonov@MacBook-Air-Dmitrij project % git status

1 file changed, 3 insertions(+), 3 deletions(-)
12 б). 2 способ добавить в индекс, затем сделать коммит
dmitrijantonov@MacBook-Air-Dmitrij project % git add -u
dmitrijantonov@MacBook-Air-Dmitrij project % git commit -m "..."
[main 6d4ba94] ...
1 file changed, 4 insertions(+)
12 в). 3 способ Добавить все изменения в индекс и сделать коммит в один шаг
dmitrijantonov@MacBook-Air-Dmitrij project % git commit -a -m "code: add sum of a,b"
