- Unstaged Changes: To check changes in the working directory that haven’t been staged yet:
git diff- This shows differences between your current working directory and the last commit.
Comparing Specific Commits
- Commit Differences: For comparing changes between two specific commits:
git diff <commit1> <commit2>- Replace
<commit1>and<commit2>with the respective commit hashes.
Focusing on a Specific File
- File-Specific Changes: To compare a specific file between the working directory and the last commit:
git diff <file>
