🔍 What Is git show?
git show displays one or more Git objects, primarily commits. It’s most commonly used to inspect a single commit’s metadata and code changes.
It combines the output of:
git log -1(commit info)git diff(code changes)
🧰 Basic Syntax
git show [<object>]
Where <object> is typically a commit hash, branch name, tag, or even HEAD.
🔎 Default Output Structure
Example:
git show 3f7a1e2
Output:
commit 3f7a1e2b12c9a8d987a9c1a9b19ef0a2a3b01dce
Author: John Doe <john@example.com>

- timeout = 3000;
+ timeout = 5000;
+ logError("Timeout updated for mobile devices");
Sections:
- Commit metadata (hash, author, date)
- Commit message
- Unified diff output (actual code changes)
🧪 Common Examples and Use Cases
🔹 1. Show the Latest Commit
git show
# or
git show HEAD
💡 Displays details for the tip of the current branch.
🔹 2. Show a Specific Commit by Hash
git show 3f7a1e2
💡 Use partial or full hash to inspect that commit’s changes.
🔹 3. Show a Commit on Another Branch
git show feature-branch
# or
git show origin/main
💡 Useful for previewing remote or unmerged commits.
🔹 4. Show a File’s Change in a Commit
git show 3f7a1e2:path/to/file.txt
💡 Outputs the snapshot of that file in the given commit.
🎛️ Useful git show Options
| Option | Description |
|---|---|
--stat | Summary of file changes |
--name-only | Show only names of changed files |
--name-status | Show changed file names with status (A, M, D) |
--oneline | Display commit hash and message on one line |
--pretty=format:"..." | Customize commit log output |
--quiet | Suppress diff output |
🔎 Example with --stat:
git show --stat HEAD
Output:
login.js | 3 ++-
1 file changed, 2 insertions(+), 1 deletion(-)
📁 Show Specific Objects with Git Show
Git can inspect not just commits, but also other Git objects:
🔹 Show File in a Specific Commit:
git show 3f7a1e2:README.md
🔹 Show Tag Details:
git show v1.0.0
If the tag is annotated, this shows metadata and commit.
⚠️ Common Pitfalls and Fixes
- ❌ “fatal: bad object” error – Make sure the commit hash or reference exists.
- ❌ Too much output – Use
--name-onlyor--statto reduce noise. - ❌ Misinterpreting diff – Remember: lines starting with
+are additions,-are deletions.
✅ Best Practices for Using git show
- Use it before code review to inspect what exactly changed.
- Combine with
--name-statusfor quick summaries. - Use
git show <commit>:<file>to recover or copy old file versions. - Pair with
git logto traverse and inspect older changes.
🧩 GUI Tools for Commit Inspection
- VS Code Source Control View – Click a commit to see full metadata and file diff.
- Sourcetree – Commit detail pane shows what
git showdoes. - GitKraken – Visual commit browser with inline diffs and history.
