The administrator should run "echo .DS STORE >> .gitignore" from the root of the local repository before the next commit to ensure the file is not uploaded again in future commits. This command will append the file name .DS STORE to the end of the .gitignore file, which is a special file that tells Git to ignore certain files or directories that should not be tracked or uploaded to the repository. By adding .DS STORE to the .gitignore file, the administrator will prevent Git from staging, committing, or pushing this file in the future.
