Отчет по лабораторной работе № 2 "Система контроля версий Git"

Выполнил: Ефремов С. И.
Группа:   А-02-23
Проверил: :)

Примечание: работа выполнялась на Windows.

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

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$

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

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$ ls

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$

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

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$ mkdir alice

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$ mkdir bob

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002
$ cd alice

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice
$ mkdir project

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice
$ cd project

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project
$ cd ..

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice
$ cd project

4. Инициализировал репозитарий:

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project
$ git init
Initialized empty Git repository in C:/Users/adamb/Desktop/lab002/alice/project/.git/

5. Настроил репозитарий Алисы, чтобы коммиты были от её имени: 

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git config user.name 'Alice (EfremovSI)'

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git config user.email 'YefremovSI@mpei.ru'

6.Проверка состояния рабочей папки
adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git status
On branch master - находимся на ветке "мастер"

No commits yet - коммиты ещё не сделаны 

Untracked files: - файлов под гитом пока нет.
  (use "git add <file>..." to include in what will be committed)
        main.cpp
        obj/
        project.cbp

nothing added to commit but untracked files present (use "git add" to track) - пока ничего не добавлено в коммит

7. Начало отслеживания main.cpp и повторная проверка состояния.

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git add main.cpp

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git status
On branch master

No commits yet

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)
        new file:   main.cpp    -    занесёт под гит

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

8. Создание первого коммита и переименование ветки (т.к. старая версия GIT)

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git commit -m 'code: заготовка программы'
[master (root-commit) 749d3e0] code: заготовка программы
 1 file changed, 9 insertions(+)
 create mode 100644 main.cpp

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (master)
$ git branch -m main

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$

9.Занесение project.cbp под гит и создание коммита с ним.

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/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

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git commit -m 'build: добавлен файл проекта'
[main ecebc32] build: добавлен файл проекта
 1 file changed, 40 insertions(+)
 create mode 100644 project.cbp

10. Повторная проверка состояния

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/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       -     изменение с "new file" на "modified", т.к. тело кода в main.cpp было изменено.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        obj/
        project.depend

no changes added to commit (use "git add" and/or "git commit -a")



11.Создание коммитов с изменениями разными способами.

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git add main.cpp

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git commit -m 'code: ввод двух чисел'
[main 44e806f] code: ввод двух чисел
 1 file changed, 3 insertions(+), 1 deletion(-)

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git add -u

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git commit -m 'code: вывод суммы'
[main 8bda21b] code: вывод суммы
 1 file changed, 1 insertion(+), 1 deletion(-)

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git commit -a -m 'code: вывод разности'
[main a209f26] code: вывод разности
 1 file changed, 2 insertions(+), 1 deletion(-)


12. Создание .gitignore (из-за Windows 11 я не смог создать его по инструкции)
 	
adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ touch .gitignore

13. Игнорирование bin, obj, project.layout:

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git status
On branch main
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .gitignore
        main.o
        project.depend
        project.layout

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

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git status
On branch main
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .gitignore
        main.o
        project.depend

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

14. Коммит для .gitignore

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git add .gitignore

adamb@GUCC-GANG MINGW64 ~/Desktop/lab002/alice/project (main)
$ git commit -m 'git: игнорирование бинарных файлов'

15. Попробовал команду git log --stat
