There are a few methods of telling git what files to ignore. + +.gitignore +---------- + +If you create a file in your repo named `.gitignore` git will use its rules when looking at files to commit. Note that git will **not** ignore a file that was already tracked before a rule was added to this file to ignore it. In such a case the file must be un-tracked, usually with `git rm --cached filename` + +This file can be committed into the repo, thus sharing the rule list with any other users that clone the repo. + +Note that you can create a `.gitignore` in any subpath to have its rules applied at that path. Sometimes an empty `.gitignore` file is used as a placeholder for an empty path, for example to force git to generate a `log/` path for your development environment to use. + +Global .gitignore +------------- + +A global .gitignore file can also be used by adding one to your global git config. For example, you might create the file `~/.gitignore_global` and add some rules to it. To add this to your config, run `git config --global core.excludesfile ~/.gitignore_global` + +Some good rules to add to this file: + +<pre> +# Compiled source # +################### +*.com +*.class +*.dll +*.exe +*.o +*.so + +# Packages # +############ +# it's better to unpack these files and commit the raw source +# git has its own built in compression methods +*.7z +*.dmg +*.gz +*.iso +*.jar +*.rar +*.tar +*.zip + +# Logs and databases # +###################### +*.log +*.sql +*.sqlite + +# OS generated files # +###################### +.DS_Store? +ehthumbs.db +Icon? +Thumbs.db +</pre> + +Repo exclude +----------- + +Local per-repo rules can be added to the `.git/info/exclude` file in your repo. These rules *are not committed* with the repo so they are not shared with others. This method can be used for locally-generated files that you don't expect other users to generate, like files created by your editor. + +Links +----- + +* [Pro Git](http://progit.org/book/ch2-2.html) +* [gitignore man page](http://www.kernel.org/pub//software/scm/git/docs/gitignore.html) |
