+# Globbing For All Directories In Zsh
+
+Globbing in Zsh is an expressive way to generate filenames for commands.
+This includes working with directories. If I'd like to run a command against
+all directories in the current directory, I can employ the `*(/)` globbing
+pattern.
+
+```bash
+$ echo *(/)
+one three two
+```
+
+What about all directories in the root directory?
+
+```bash
+$ echo /*(/)
+/Applications /Library /Network /System /Users /Volumes /bin /cores /dev /home /net /opt /private /sbin /usr
+```
