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

Выполнил: Кислов А.Г.
Группа:   А-03-22
Проверил: 

Примечание: работа выполнялась на Windows.

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

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02
$



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

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ls

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02
$

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

ivan@HOME-PC MINGW32 /c/Users/ivan/Desktop/lab02
$ mkdir alice

ivan@HOME-PC MINGW32 /c/Users/ivan/Desktop/lab02
$ mkdir bob

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ cd alice

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ mkdir project

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ cd project

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project
$ cd ..

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ cd ..

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02
$ cd alice

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice
$ cd project

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project
$ ls

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project
$

4. Инициализировал репозитарий:

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project
$ git init
Initialized empty Git repository in C:/Users/Артем/OneDrive/Рабочий стол/lab02/alice/project/.git/

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ ls -A
.git/

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ git config user.name 'Alice (KislovArG)'

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ git config user.email 'kislovartem12@gmail.com'

имя ветки буду менять после создания первго коммита

5. Создание коммитов:

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/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)
        bin/
        main.cpp
        obj/
        project.cbp

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

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ git add main.cpp

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/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)
        bin/
        obj/
        project.cbp

при первом статусе у нас отобразились файлы которые не занесены под Git, далее мы занесли под Git main

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (master)
$ git commit -m 'code: заготовка программы'

$ git branch -m main

Артем@LAPTOP-05DPLC18 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

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m 'build: добавлен файл проекта'
[main 52122b5] build: добавлен файл проекта
 1 file changed, 40 insertions(+)
 create mode 100644 project.cbp

6. Создание коммитов с изменениями:

Артем@LAPTOP-05DPLC18 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")

показывает что были изменения но мы не зафиксировали их

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add main.cpp

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m "code: ввод двух чисел"
[main 8026dda] code: ввод двух чисел
 1 file changed, 4 insertions(+), 2 deletions(-)

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add -u

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m "code: вывод суммы a и b"
[main 8b9b7ad] code: вывод суммы a и b
 1 file changed, 1 insertion(+)

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -a -m "code: вывод разности a и b"
[main fb9dba9] code: вывод разности a и b
 1 file changed, 2 insertions(+), 1 deletion(-)

7. Игнорирование файлов

Артем@LAPTOP-05DPLC18 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
        obj/
        project.depend

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

Артем@LAPTOP-05DPLC18 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
        project.depend

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

игнорируем файлы и создаем коммит

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git add .gitignore

Артем@LAPTOP-05DPLC18 MINGW64 ~/OneDrive/Рабочий стол/lab02/alice/project (main)
$ git commit -m "git: игнорирование файлов"
[main ee1d9a6] git: игнорирование файлов
