# Log filter

How to filter results in the commit history?

There are various arguments you can add to `git log`. Here are some commonly used attributes you can filter on 

* Author
  * `git log --author="Jason"`
* Date
  * `git log --since="2023-07-22"`
  * `git log --before="2023-06-01"`
  * `git log --after="1998-05-30"`
* Messege
  * `git log --grep="bug"`
* File
  * `git log -- analyse.py`

You can combine these filters, e.g. 

```
git log --author="David Johns" --before="2023-07-20" --after="2020-01-01" --grep="registration"
```
