3 min readWhen merging branches in git, you may want to ignore specific files to prevent conflicts or unwanted changes. To do this, you can use the git merge command with the --no-commit option to stop before the actual commit is made. Then, reset the changes for the specific files using git checkout -- command. Finally, you can continue with the merge by using git commit -m "Merge branch" command. This way, you can exclude specific files from being merged while combining branches in git.
