+# Exclude A Directory With Find
+
+Using `find` is a handy way to track down files that meet certain criteria.
+However, if there are directories full of irrelevant files, you may end up
+with a lot of noise. What you want to do is exclude or ignore such
+directories. For example, you probably don't want `find` to return results
+from the `.git` directory of your project.
+
+Specific directories can be excluded by combining the `-not` and `-path`
+arguments.
+
+For instance, to see all files modified within the last 10 days, but not
+including anything in the `.git` directory, run the following:
+
+```bash
+$ find . -type f -not -path './.git/*' -ctime -10
+```
