Git Ignore Files: Other Exclusion Methods Besides .gitignore

Git, besides `.gitignore`, offers multiple ways to ignore files for different scenarios. `.git/info/exclude` is only for the local repository and its rules are not shared; directly add ignore rules here (e.g., personal IDE configurations). `git update-index --assume-unchanged` is used for tracked files to prevent Git from checking modifications (e.g., local configuration files). `--skip-worktree` is stricter, prohibiting Git from tracking sensitive files (e.g., passwords). `git rm --cached` can remove a tracked file from the repository while keeping it locally. Selection guide: Use `.gitignore` for daily general rules to share them, use `.git/info/exclude` for local personal needs, apply the above two for ignoring already tracked files, and use `git rm --cached` to remove files. Mastering these allows flexible management of the tracking scope, avoiding repository bloat or information leakage.

Git Ignore Files: Beyond .gitignore, What Other Methods Are There to Exclude Unwanted Files?

In addition to .gitignore, Git provides four flexible methods to control file ignoring: 1. **Local Exclusive Ignoring**: `.git/info/exclude` applies rules only to the current repository and is not committed. It is suitable for personal temporary ignores (e.g., IDE caches, test data). 2. **Global General Ignoring**: `core.excludesfile` creates a global rule file (e.g., ~/.gitignore_global) and configures Git to read it. All repositories automatically apply these rules, ideal for uniformly ignoring editor/system files (e.g., .idea, .DS_Store). 3. **Force Adding Ignored Files**: `git add -f filename` skips .gitignore rules and temporarily stages ignored files (e.g., for local sensitive configuration changes). 4. **Debugging Ignore Rules**: `git check-ignore filename` checks if a file is ignored, assisting in troubleshooting rule issues. Choose based on scenarios: use exclude for local temporary ignores, core.excludesfile for global uniformity, -f for temporary additions, and check-ignore for debugging.
