Отчет по лабораторной работе № 2 «Система контроля версий Git»

Выполнил: Кантимиров Д.Д.
Группа: А-01-24
Проверил: 

Примечание: работа выполнялась на Windows.

1.Создал на рабочем столе каталог lab02 и запустил в нем Git Bash, приглашение:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$
2.Просмотрел файлы в рабочем каталоге можно командой ls — пусто:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$ ls
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$
3.Создал каталоги Алисы и Боба, создал каталог project, изучил команду cd в процессе:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$ mkdir alice
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$ mkdir bob
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$ cd alice
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice
$ mkdir project
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice
$ cd ..
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02
$ cd alice

Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice
$ cd project
4. Инициализируем репозитарий в текущем каталоге (project): 
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project
$ git init
Initialized empty Git repository in C:/Users/Даниил/Desktop/lab02/alice/proje
ct/.git/
5. Настройка репозитария Алисы:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git config user.name 'Alice (KantimirovDD)'
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git config user.email 'cassian3907@gmail.com'
6.Создание в CodeBlocks проекта “project“ в репозитарии Алисы.
7.Просмотр состояния рабочей комнаты:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git status
On branch master 
No commits yet
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        main.cpp
        project.cbp
nothing added to commit but untracked files present (use "git add" to track)
8.Добавляем файл main.cpp в индекс:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git add main.cpp
9.Проверка состояния рабочей копии:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/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
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        project.cbp
10.Выполняем коммит с файлом main.cpp и сообщением:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git commit -m 'code: заготовка программы'
[master (root-commit) 24796af] code: заготовка программы
 1 file changed, 9 insertions(+)
 create mode 100644 main.cpp
11.Поменяем имя ветки на main:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (master)
$ git branch -m main
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
$
12.Добавил файл project.cbp в индекс и создал коммит с ним:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add project.cbp
warning: in the working copy of 'project.cbp', LF will be replaced by CRLF th
e next time Git touches it
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
$ git commit -m 'build: добавлен файл проекта'
[main 5b81705] build: добавлен файл проекта
 1 file changed, 40 insertions(+)
create mode 100644 project.cbp
13.Проверка состояния репозитария после обновления кода:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
$ git status
On branch main
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)

        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")
14.Добавление коммитов и проверка статуса:
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add main.cpp
Даниил@DESKTOP-98N2NGJ MINGW64 ~/Desktop/lab02/alice/project (main)
