+# File Type Info With File
+
+Use the `file` utility to determine the type of a file:
+
+```bash
+$ file todo.md
+todo.md: ASCII English text
+
+$ file Hello.java
+Hello.java: ASCII C++ program text
+
+$ file Hello.class
+Hello.class: compiled Java class data, version 52.0
+```
+
+The `Hello.java` file isn't exactly a C++ program, but close enough.
