3. Drafting - Section by Section (incortering word count and constraints):

   • Constraint Check: No meta sentences. Start directly with the paragraph. Match language (English). Use H2/H3, bold, lists It's one of those things that adds up. Nothing fancy..

   • Intro: Understanding how to view files changed in a specific Git commit is a fundamental skill for any developer. Whether you are auditing your own codebase, investigating a bug, or collaborating with a team, being able to pinpoint exactly which files were modified, added, or deleted in a given commit is invaluable. The git show command provides a powerful way to inspect the contents of a commit, but mastering its options allows you to extract precisely the information you need regarding file modifications. This guide will walk you through everything you need to know about using git show to see which files were changed in a commit, breaking down the commands, flags, and practical examples And it works..

   • Understanding Git Commits and File Changes: Before diving into the commands, it is essential to understand how Git tracks changes. When you commit a change, Git doesn't just save the new file; it creates a snapshot of the repository at that specific point in time. Each commit contains a tree object that represents the entire directory structure, along with blob objects that represent the actual file contents. When you use git show, you are essentially looking at the diff between the commit you are viewing and its parent commit. This diff highlights exactly which files were altered, added, or removed, along with the nature of those changes (insertions and deletions).

   • Primary Command: git show The most direct way to see files changed in a commit is simply by passing the commit hash or branch name to the git show command. git show <commit-hash> This displays the full diff, including the list of files that were affected. Even so, the default output can be overwhelming because it shows every single line of code that was added or removed, not just the files themselves That's the part that actually makes a difference..

   • Filtering Output with Flags To make this information more digestible, Git provides several flags that modify the output of git show. Here are the most useful ones for isolating file changes:

     • --stat: This flag summarizes the changes. Instead of showing line-by-line diffs, it provides a count of additions and deletions per file, giving you a quick overview of the impact of the commit.
     • --name-only: If you only care about which files changed without seeing the actual code diffs, this flag strips away the code changes and leaves just the filenames.
     • --name-status: This goes a step further by also showing the status of each file (e.g., A for Added, M for Modified, D for Deleted).
     • --diff-filter=[...]: For advanced users, this allows you to filter out certain types of changes (like d for deleted or a for added), focusing only on modifications.

   • Step-by-Step Examples Let's look at practical scenarios where you would use these commands.

     Scenario 1: Seeing a quick summary of file changes. Open your terminal and run: git show --stat <commit-hash> This will output a table-like structure where each row represents a file, showing the filename, the number of lines added, and the number of lines deleted Which is the point..

     Scenario 2: Listing only the names of changed files. If you want a simple list of filenames, execute: git show --name-only <commit-hash> You will see a clean list of filenames that were touched in that commit.

     Scenario 3: Getting both names and their statuses. For a slightly more detailed view: git show --name-status <commit-hash> This is particularly helpful when a commit adds a new feature file but also deletes an old utility file, as you can clearly see both actions in the output That alone is useful..

   • Alternative Methods While git show is the go-to command, there are other ways to achieve similar results Small thing, real impact..

     Using git diff: You can compare a commit against its parent using git diff. git diff <commit>^ <commit> Note the caret (^) symbol, which refers to the parent commit. This method is essentially the underlying mechanism that git show uses under the hood for the diff portion That alone is useful..

     Using git log with custom formatting: If you want to see a chronological list of commits with file changes, you can use git log with the --stat or --name-only flags: git log --stat <branch-name> or git log --name-only <branch-name>

   • Handling Edge Cases and Advanced Scenarios Sometimes, the output from git show might not behave exactly as expected. Here are a few edge cases to be aware of:

     Binary Files: Git cannot perform line-by-line diffs on binary files (like images or compiled executables). In this case, git show will display a message like "Binary diff" instead of showing the actual changes. You can use --num-out to get a rough estimate of the size difference, but you won't see the actual content changes That's the whole idea..

     Renames: Git tries to detect when a file has been renamed rather than deleted and re-added. By default, git show might show a deletion followed by an

an addition. To make this clearer, you can enable rename detection explicitly:

git show -M <commit-hash>

This tells Git to look for files that are similar enough to be considered renames rather than independent delete/add pairs. Which means the output may then show something like R100 old-name. Think about it: txt -> new-name. txt, along with any content changes.

For merge commits, the default combined diff can be tricky. If you want to see what a merge introduced relative to its first parent, run:

git show --first-parent <merge-commit-hash>

Or simply compare parents directly:

git diff <merge-commit-hash>^1 <merge-commit-hash>

This can help isolate changes that came in from the merged branch without the noise of conflict resolutions.

You can also refine how git show presents changes. While --patch is often the default, flags like --stat, --name-only, and --name-status let
