Git file blame

Git blame provides more information about every line in a file, including the last modified time, author, and commit hash.

Prerequisites:

  • The file type must be text-based. The GitLab UI does not display git blame results for binary files.

To view the blame for a file:

  1. On the left sidebar, select Search or go to and find your project.
  2. Select Code > Repository.
  3. Select the file you want to review.
  4. In the upper-right corner, select Blame, and go to the line you want to see.

When you select Blame, this information is displayed:

To see the precise date and time of the commit, hover over the date. The vertical bar to the left of the user avatar shows the general age of the commit. The newest commits have a dark blue bar. As the age of the commit increases, the bar color changes to light gray.

Blame previous commit

To see earlier revisions of a specific line:

  1. On the left sidebar, select Search or go to and find your project.
  2. Select Code > Repository.
  3. Select the file you want to review.
  4. In the upper-right corner, select Blame, and go to the line you want to see.
  5. Select View blame prior to this change () until you’ve found the changes you’re interested in viewing.

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:

  1. Run this command git blame README.md.
  2. If the line you want to see is not in the first page of results, press Space until you find the line you want.
  3. To exit out of the results, press Q.

The git blame output in the CLI looks like this:
