# Git file blame **(FREE)**
[Git blame](https://git-scm.com/docs/git-blame) provides more information
about every line in a file, including the last modified time, author, and
commit hash. To view it for a file:
1. Go to your project's **Repository > Files**.
1. Select the file you want to review.
1. In the upper right corner, select **Blame**.
When you select **Blame**, this information is displayed:
![Git blame output](img/file_blame_output_v12_6.png "Blame button output")
If you hover over a commit in the UI, the commit's precise date and time
are shown.
## Blame previous commit
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/19299) in GitLab 12.7.
To see earlier revisions of a specific line, click **View blame prior to this change**
until you've found the changes you're interested in viewing:
![Blame previous commit](img/file_blame_previous_commit_v12_7.png "Blame previous commit")
## Associated `git` command
If you're running `git` from the command line, the equivalent command is
`git blame <filename>`. For example, if you want to find `blame` information
about a `README.md` file in the local directory, run the following command:
```shell
git blame README.md
```
The output looks similar to the following, which includes the commit time
in UTC format:
```shell
