Отчет по лабораторной работе № 2 "Система контроля версий Git"
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 <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)
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 <file>..." to unstage)
new file: main.cpp
Untracked files:
(use "git add <file>..." 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
