On Gitlab, how to compare a file of two different commits

Question

On Gitlab, how to compare a file of two different commits? I know that that on command line git, the command is:

git diff commit1 commit12 -- file_name
         


        

Answer 1

None of the other answers had the correct steps to show a diff between two branches via the Gitlab GUI in its current version. To do so:

1. Go to your project
2. Hover over "Repository" in the side-menu and click "Branches"
3. Next to the branch you wish to compare, click the "Compare" button on the right.
4. You can then change the target branch from master (or whatever your default branch is called) if you wish.
5. At the top is commits. Scroll down to see the actual diffs for each modified file.
6. Scroll to the specific file you want to compare and click to expand if necessary.
