1

Initialize a Git repository and create two commits

Run the following commands to initialize a Git repository, create a file named file.txt with content Hello, add it, commit with message First commit, then change the file content to Hello, Git! and commit again with message Second commit.

Git

# Initialize Git repo and create two commits
# Your code here

Need a hint?

Use git init to start the repo, then create and commit changes with git add and git commit -m.

2

Find the commit hashes using git log

Run git log --oneline to list the commits with their short hashes and messages.

Git

git init

echo Hello > file.txt

git add file.txt

git commit -m "First commit"

echo "Hello, Git!" > file.txt

git add file.txt

git commit -m "Second commit"

# Run git log to see commit hashes
# Your code here

Need a hint?

Use git log --oneline to see short commit hashes and messages.

3

Use git show with a commit hash to view details

Copy the short commit hash of the first commit from git log --oneline. Then run git show <commit-hash> replacing <commit-hash> with the copied hash to see detailed commit information.

Git

git init

echo Hello > file.txt

git add file.txt

git commit -m "First commit"

echo "Hello, Git!" > file.txt

git add file.txt

git commit -m "Second commit"

git log --oneline

# Replace  with the first commit's hash below
# Your code here

Need a hint?

Use git show <commit-hash> to see the commit message, author, date, and changes.

4

Display the commit details output

Run the git show <commit-hash> command you wrote in the previous step and observe the output showing commit details.

Git

git init

echo Hello > file.txt

git add file.txt

git commit -m "First commit"

echo "Hello, Git!" > file.txt

git add file.txt

git commit -m "Second commit"

git log --oneline

git show 

# Run the command to see commit details
# Your code here

Need a hint?

The output should show the commit hash, author, date, commit message, and the diff of changes.
