# Отчет по лабораторной работе № 2 «Система контроля версий Git»
Выполнил: Мордашов С. A \
Группа: А-01-24 \
Проверил: Филатов С.A
Примечание: работа выполнялась на Windows.
1. Создал на рабочем столе каталог lab02 и запустил в нем Git Bash, приглашение:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$
```
2. Просмотрел файлы в рабочем каталоге можно командой `ls` — пусто:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ ls
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$
```
3. Создал каталоги Алисы и Боба, создал каталог `project`,
изучил команду `cd` в процессе:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ mkdir alice
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ mkdir bob
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ cd bob
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/bob
$ cd ..
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ cd alice
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ mkdir project
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ ls
project/
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ cd project
```
4. Инициализировал репозитарий:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project
$ git init
Initialized empty Git repository in C:/Users/Mi/OneDrive/Рабочий стол/lab02/alice/project/.git/
```
У меня имя ветки по умолчанию не настроено.
Git создал ветку под названием `master`, что видно в приглашении терминала. По описанию из методички должна была появиться подсказка `hint:` для изменения имени, но в моей версии `Git-2.48.1-64-bit` она не высветилась.
5. Изменим имя ветки `master`, на `main` для удобства. Применим команду `git branch -m main`, а затем проверим, создался ли репозиторий, c помощью команды `ls -A`:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ git branch -m main
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ ls -A
.git/
```
6. Настроим репозитарий Алисы, чтобы коммиты были от ее имени:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git config user.name 'Alice (MordashovSA)'
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git config user.email 'MordashovSA@mpei.ru'
```
7. Запустил CodeBlocks и создал проект в репозитарии Алисы:
##### Параметры были выбраны такие:
Project title: `project`
Folder to create project in: `C:\Users\Mi\OneDrive\Рабочий стол\lab02\alice`
Project filename: `project.cbp`
Resulting filename: `C:\Users\Mi\OneDrive\Рабочий стол\lab02\alice\project\project.cbp`
##### Структура файлов выглядит таким образом:
```
lab02
├── alice
│ └── project <--------- текущий рабочий каталог
│ ├── .git <--------- создан командой "git init"
│ ├── bin <--------- создан CodeBlocks при сборке
│ ├── obj <--------- (то же самое)
│ ├── main.cpp <-- код программы
│ └── project.cbp <-- файл проекта
└── bob
```
8. Вернувшись в Git Bash, просмотрим состояние рабочей копии:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main - выведена информация о текущей ветке main
No commits yet - в базу данных не помещено ни одного коммита
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
main.cpp
obj/
project.cbp
nothing added to commit but untracked files present (use "git add" to track) - чтобы включить неотслеживаемый файл в коммит, нужно использовать команду git add.
```
9. Добавим файл main.cpp в индекс и закомили его:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add main.cpp
```
проверили внесение файла:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
No commits yet
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: main.cpp
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
obj/
project.cbp
```
закоммили:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m 'code: заготовка программы'
[main (root-commit) 1476d9a] code: заготовка программы
1 file changed, 9 insertions(+)
create mode 100644 main.cpp
```
аналогично с project.cbp:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add project.cbp
warning: in the working copy of 'project.cbp', LF will be replaced by CRLF the next time Git touches it
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: project.cbp
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
obj/
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m 'build: | add project file'
[main 0f25a14] build: | add project file
1 file changed, 38 insertions(+)
create mode 100644 project.cbp
```
10. Различия между случаем, когда добавлялся новый файл, и когда изменился существующий
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: main.cpp
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
obj/
no changes added to commit (use "git add" and/or "git commit -a")
```
11. Закомим main.cpp снова 1 способом (ввод a, b):
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add main.cpp
git commit -m "..."
[main f6890c8] ...
1 file changed, 4 insertions(+), 1 deletion(-)
```
12. Коммим ещё a+b
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: main.cpp
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
obj/
no changes added to commit (use "git add" and/or "git commit -a")
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add -u `git add -u — это команда для подготовки к коммиту только изменённых и удалённых файлов, но не любых неотслеживаемых файлов.`
git commit -m "..."
[main 014403c] ...
1 file changed, 1 insertion(+)
```
13. Коммим ещё и a-b :
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: main.cpp
Untracked files:
(use "git add <file>..." to include in what will be committed)
bin/
obj/
no changes added to commit (use "git add" and/or "git commit -a")
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -a -m "..." - `— это команда в системе контроля версий Git, которая позволяет пропустить этап подготовки (с помощью git add) для изменённых файлов и зафиксировать их за один шаг.`
[main cc90111] ...
1 file changed, 2 insertions(+), 2 deletions(-)
```
14. Игнорирование файлов католога project c помощью .gitignore, и его занесение в git (создание коммита)
Содержимое .gitignore:
/bin
/obj
/project.layout
/project.depend
занесение:
```
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Untracked files:
(use "git add <file>..." to include in what will be committed)
.gitignore
nothing added to commit but untracked files present (use "git add" to track)
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add .gitignore
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git status
On branch main
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: .gitignore
Mi@DESKTOP-F1KO4G0 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m 'git'
[main c4878e1] git
1 file changed, 4 insertions(+)
create mode 100644 .gitignore
```
15. Просмотрели журнал коммитов 3-мя способами:
1-й:
```

17. просмотр в gitbash самих коммитов
1 C помощью HEAD , а потом с помощью названия ветки просмотрим последний коммит
