+Assume you have a folder structure:
+<code>
+.
+├── bar
+│   ├── foo
+│   │   └── baz
+│   │       └── hurz
+│   │           └── lolz
+│   │               └── hello.txt
+│   └── poit.txt
+└── fnord.txt
+</code>
+Then **ls** with single star **<nowiki>*</nowiki>** would list:
+<code bash>
+ls *.txt
+fnord.txt
+</code>
+The double star operator **<nowiki>**</nowiki>** will work on the subfolders.  The output will look like:
+<code bash>
+ls **/*.txt
+bar/foo/baz/hurz/lolz/hello.txt  bar/poit.txt  fnord.txt
+</code>
