-
-## More on the `git status` Command
-
-- `git status`: Show the status of changes as untracked, modified, or staged.
-
-    ```shell
-    git status
-    ```
-
-    ```shell
-    On branch 2024-10-21_pro-git
-    Changes not staged for commit:
-    (use "git add <file>..." to update what will be committed)
-    (use "git restore <file>..." to discard changes in working directory)
-            modified:   README.md
-            modified:   pro-git/chapter-01/README.md
-
-    Untracked files:
-    (use "git add <file>..." to include in what will be committed)
-            pro-git/chapter-02/
-
-    no changes added to commit (use "git add" and/or "git commit -a")
-    ```
-
-- Shorter `git status`:
-
-    ```shell
-    git status --short
-    ```
-
-    ```shell
-     M README.md
-     M pro-git/chapter-01/README.md
-    ?? pro-git/chapter-02/
-    ```
-
-  - the first column represents the status of the staging area[^1]
-  - the second column represents the status of the working directory[^1]
-
-## Ignoring Files
-
-Rules of `.gitignore` files:
-
-- Blank lines or lines starting with `#` are ignored.
-- Standard [glob patterns](#glob-patterns) work, and will be applied recursively throughout the entire working directory (e.g. `*.log`).
-- You can start patterns with a forward slash (`/`) to avoid recursivity (e.g. `/*.log`).
-- You can end patterns with a forward slash (`/`) to specify a directory (e.g. `log/`).
-- You can negate a pattern by starting it with an exclamation point (`!`).
-
-### Glob patterns
-
-Glob patterns are regex[^2] for shell environments. Here are some examples:
-
-- `*`: matches zero or more characters
-- `[abc]`: matches any of the characters a, b, or c
-- `?`: matches a single character
-- brackets enclosing characters separated by a hyphen (`-`) represent a range (e.g. `[1-5]` matches any digit from 1 to 5)
-- two asterisks (`**`) represent any number of directories (e.g. `a/**/z` matches `a/z`, `a/b/z`, `a/b/c/z`, etc.)
-
-### Example `.gitignore` file[^3]
-
-```gitignore
-# ignore all .a files
-*.a
-
-# but do track lib.a, even though you're ignoring .a files above
-!lib.a
-
-# only ignore the TODO file in the current directory, not subdir/TODO
-/TODO
-
-# ignore all files in any directory named build
-build/
-
-# ignore doc/notes.txt, but not doc/server/arch.txt
-doc/*.txt
-
-# ignore all .pdf file in the doc/ directory and any of its subdirectories
-doc/**/*.pdf
-```
-
-## Compare Changes Made with `git diff`
-
-Use `git status` as a primer for this:
-
-```shell
-git status
-```
-
-```shell
-On branch 2024-10-21_pro-git
-Changes not staged for commit:
-  (use "git add <file>..." to update what will be committed)
-  (use "git restore <file>..." to discard changes in working directory)
-        modified:   README.md
-        modified:   pro-git/chapter-01/README.md
-
-Untracked files:
-  (use "git add <file>..." to include in what will be committed)
-        pro-git/chapter-02/
-
-no changes added to commit (use "git add" and/or "git commit -a")
-```
-
-Let's check what was changed in `README.md`:
-
-```shell
-git diff README.md
-```
-
-```shell

+* | ed64291 First PR for `gnu grep` (#1)
+|/  
+* fe49b8b Initial commit
+```
+
+### Common options to `git-log`
+
+- `-p` or `--patch`: Show the patch introduced with each commit.
+- `--stat`: Show statistics for files modified in each commit.
+- `--shortstat`: Show only the changed/insertions/deletions line from the `--stat` option.
+- `--name-only`: Show the list of files modified after the commit information.
+- `--name-status`: Show the list of files modified after the commit information, indicating the status of the changes.
+- `--abbrev-commit`: Show only the first few characters of the SHA-1 checksum instead of all 40.
+- `--relative-date`: Display the date in a relative format (e.g. "2 weeks ago") instead of using the full date format.
+- `--graph`: Show an ASCII graph of the branch and merge history beside the log output.
+- `--pretty`: Show commits in an alternate format. Options include `oneline`, `short`, `full`, `fuller`, `format`, and `email`.
+- `--oneline`: Shorthand for `--pretty=oneline --abbrev-commit` used together.

+## More on the `git status` Command
+
+- `git status`: Show the status of changes as untracked, modified, or staged.
+
+    ```shell
+    git status
+    ```
+
+    ```shell
+    On branch 2024-10-21_pro-git
+    Changes not staged for commit:
+    (use "git add <file>..." to update what will be committed)
+    (use "git restore <file>..." to discard changes in working directory)
+            modified:   README.md
+            modified:   pro-git/chapter-01/README.md
+
+    Untracked files:
+    (use "git add <file>..." to include in what will be committed)
+            pro-git/chapter-02/
+
+    no changes added to commit (use "git add" and/or "git commit -a")
+    ```
+
+- Shorter `git status`:
+
+    ```shell
+    git status --short
+    ```
+
+    ```shell
+     M README.md
+     M pro-git/chapter-01/README.md
+    ?? pro-git/chapter-02/
+    ```
