+# `find`
+
+`find` can be used both to locate files and run operations on the files it finds.
+
+## Main syntax
+
+### No options
+Without options specified, `find` alone will return a recursive index of all the files in the directory from which it is run.
+
+### Sub-directory
+If we pass a directory to `find` it will repeat the above process but specifically for that directory.
+
+```bash
+$ find i3
+i3
+i3/config
+```
+
+### Filters
+We can specify flags as filters (known as 'tests' within the program).
+
+#### Type
+Filter by type: file or directory
+
+```
+$ find -type d # return dirs only
+$ find -type f # return files only
+```
+
+Within a specified directory:
+
+```bash
+$ find i3 -type f
+```
+
+### Filename
+This is the most frequent use case: filter files by name with globbing.
+
+```bash
+$ find -name "config"
+./.git/config
+./i3/config
+```
+
+```bash
+$ find -name "*.js"
+```
+
+The same, but case insensitive: `iname`
+
+```bash
+$ find -iname "*.JS"
+```
