# Git Log
Git log lists commit history. It allows searching and filtering.
- Initiate log:
```shell
git log
```
- Retrieve set number of records:
```shell
git log -n 2
```
- Search commits by author. Allows user name or a regular expression.
```shell
git log --author="user_name"
```
- Search by comment message:
```shell
git log --grep="<pattern>"
```
- Search by date:
```shell
git log --since=1.month.ago --until=3.weeks.ago
```
