+# Globbing For Filenames In Zsh
+
+Zsh has extensive support for _globbing_ for filenames. _Globbing_ is a
+short-hand, of sorts, for generating filenames that meet certain criteria.
+The generated filenames can be used with any command you might otherwise
+provide a filename to in a unix setting.
+
+For example, consider a directory full of files including many that are
+named with numbers. You'd like to list all files that have numeric names.
+
+Doing `ls` by itself gives the following result:
+
+```bash
+$ ls
+10        11        2         3         4         801       92        code.rb   hello.txt
+```
+
+With the use of a numeric pattern, Zsh's _globbing_ helps `ls` limit the set
+of listed files to just those with numeric names:
+
+```bash
+$ ls *[0-9]
+10  11  2   3   4   801 92
+```
