Q2 - Adding and Staging Files#

Problem Statement#

Add Specific Files
Create two files, app.js and style.css. Use git add to stage only style.css. This allows selective addition of files to the staging area before committing.
Interactive Staging
Modify style.css and use git add -p to stage changes interactively. This lets you review and stage specific parts of a file.
Stage All Files Except One
Add all files in the folder to the staging area except README.md. Use a wildcard pattern to exclude the file, ensuring other files are prepared for commit.

Solution#

1. Add Specific Files#

Create the files app.js and style.css

touch app.js style.css

Stage only style.css

git add style.css

Verify the staged files

git status

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    new file:   style.css

Untracked files:
  (use "git add <file>..." to include in what will be committed)
    app.js

2. Interactive Staging#

Modify style.css (e.g., add some CSS code)

/* Example content for style.css */
body {
    background-color: #f0f0f0;
}

Use interactive staging to review changes

git add -p style.css

Git will present changes in chunks and prompt for action

Stage this hunk [y,n,q,a,d,s,e,?]?

Actions:

Press y to stage the current chunk.
Press n to skip the current chunk.
Press q to quit without staging more changes.

Verify the staged changes

git status

Example Output,

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    modified:   style.css

3. Stage All Files Except One#

Create a new file README.md alongside app.js and style.css:

touch README.md

Use a wildcard pattern to stage all files except README.md:

git add -- ':!README.md'

Verify the staged files

git status

Verify the staged files

git status

Verify the status

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
    new file:   app.js
    new file:   style.css

Untracked files:
  (use "git add <file>..." to include in what will be committed)
    README.md
