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

Выполнила: Бирюкова А.С.
Группа:    А-02-22
Проверил:  Козлюк Д.А.

Примечание: работа выполнялась на Windows.

1. Создалa на рабочем столе каталог lab02 и запустила в нем Git Bash, приглашение:

Professional@User-PC MINGW64 ~/Desktop/lab02
$

2. Просмотрела файлы в рабочем каталоге командой ls - пусто:

Professional@User-PC MINGW64 ~/Desktop/lab02
$ ls

Professional@User-PC MINGW64 ~/Desktop/lab02
$

3. Создала каталоги Алисы и Боба, создала каталог project, изучила команду сd в процессе:

Professional@User-PC MINGW64 ~/Desktop/lab02
$ mkdir alice

Professional@User-PC MINGW64 ~/Desktop/lab02
$ mkdir bob

Professional@User-PC MINGW64 ~/Desktop/lab02
$ cd alice

Professional@User-PC MINGW64 ~/Desktop/lab02/alice
$ mkdir project

Professional@User-PC MINGW64 ~/Desktop/lab02/alice
$ cd project

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project
$ cd ..

Professional@User-PC MINGW64 ~/Desktop/lab02/alice
$ cd project

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project
$

4. Инициализировала репозитарий, изменила имя ветки, настроила Git:

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project
$ git init
Initialized empty Git repository in C:/Users/Professional/Desktop/lab02/alice/project/.git/

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (master)
$ git branch -m main

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ ls -A
.git/

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git config user.name 'Alice (BiriukovaAlS)'

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git config user.email 'BiriukovaAlS@mail.ru'

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$

5. Создание коммитов.

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git status
On branch main    //расположение на ветке main

No commits yet    //пока нет коммитов

Untracked files:  //неотслеживаемые файлы
  (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)  //коммиты не были добавлены, но есть файлы, которые можно сделать отслеживаемыми

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add main.cpp

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git status
On branch main

No commits yet

Changes to be committed:			//были внесены изменения, теперь отслеживается файл main
  (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


Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git commit -m 'code: заготовка программы'
[main (root-commit) f221fcf] code: заготовка программы
 1 file changed, 9 insertions(+)
 create mode 100644 main.cpp

Professional@User-PC 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

5.1 Создание коммитов с изменениями

Professional@User-PC 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)
  (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")

Появились коммиты, пропала строчка No commits yet, изменился статус main c new file на modified

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add main.cpp

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git commit -m "calc:добавление суммы"
[main 948d41a] calc:добавление суммы
 1 file changed, 5 insertions(+), 1 deletion(-)

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add -u

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git commit -m "calc:добавление разности"

6. Игнорирование файлов

Cоздала в CodeBlocks новый файл, сохранив его под именем .gitignore

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git status
On branch main
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .gitignore
        obj/

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

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git add .gitignore

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git commit -m "git:игнорирование файлов"
[main 17067fe] git:игнорирование файлов
 1 file changed, 1 insertion(+)
 create mode 100644 .gitignore

Professional@User-PC MINGW64 ~/Desktop/lab02/alice/project (main)
$ git status
