Выполнил: Нефедов М.А. Группа: А-01-24 Проверил: Козлюк Д.А.

Примечание: работа выполнялась на Windows.

Вход в терминал и создание структуры каталогов

1. Создал на рабочем столе каталог lab02 и запустил в нем Git Bash, приглашение:

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02 $

2. Просмотрел файлы в рабочем каталоге можно командой "ls" --- пусто:

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02 $ ls

3. Создал каталоги Алисы и Боба, создал каталог "project", изучил команду "cd" в процессе:

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02 $ mkdir alice

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02 $ mkdir bob

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02 $ cd alice

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice $ mkdir project

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice $ cd project

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project $ cd ..

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice $ cd project

---

Инициализация репозитария и настройка Git

4. Инициализировал репозитарий и поменял имя ветки:

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project $ git init Initialized empty Git repository in C:/Users/I/Desktop/lab02/alice/project/.git/

I@DESKTOP-EKCEBSK MINGW64 ~/Desktop/lab02/alice (master) $ git branch -m main

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ ls -A .git/

5. Настроим репозитарий Алисы, чтобы коммиты были от ее имени:

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git config user.name 'Alice (NefedovMA)'

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git config user.email 'NefedovMikA@mpei.ru'

---

Занесение файлов под контроль версий

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git status On branch master //Отображает статус ветки master

No commits yet //Еще не было сделано коммитов

Untracked files: //Файлы которые не трекаются (use "git add ..." 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)

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git add main.cpp

6. Еще раз посмотрел состояние рабочей копии

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git status On branch master

No commits yet

Changes to be committed: //Показывает изменения которые будут закоммичены (use "git rm --cached ..." to unstage) new file: main.cpp

Untracked files: (use "git add ..." to include in what will be committed) bin/ obj/ project.cbp

7. Сделал первый коммит

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git commit -m 'code: заготовка программы' [master (root-commit) ea154c7] code: заготовка программы 1 file changed, 9 insertions(+) create mode 100644 main.cpp

---

Составление сообщений к коммитам

9. Добавил файл project.cbp в индекс и сделал коммит с ним

I@DESKTOP-EKCEBSK MINGW64~/Desktop/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

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git commit -m 'build: add project file' [main d864b88] build: add project file 1 file changed, 40 insertions(+) create mode 100644 project.cbp

Игнорирование файлов

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git status On branch main Untracked files: (use "git add ..." to include in what will be committed) .gitignore obj/ project.depend

nothing added to commit but untracked files present (use "git add" to track)

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git status On branch main Untracked files: (use "git add ..." to include in what will be committed) .gitignore project.depend

nothing added to commit but untracked files present (use "git add" to track)

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git add .gitignore

10. Создал коммит с .gitignore, тема — git.

I@DESKTOP-EKCEBSK MINGW64~/Desktop/lab02/alice/project (main) $ git commit -m 'build: git' [main f507a7a] build: git 1 file changed, 2 insertions(+) create mode 100644 .gitignore
