+Working with with sitemap xml files in AWS S3 today and the default sort is a bit hard to read. 
+
+Example: 
+
+```shell
+$ aws s3 ls s3://cool-bucket | awk '{print $4}'
+sitemap.brands.xml
+sitemap.episode.0.xml
+sitemap.episode.1.xml
+sitemap.episode.10.xml
+sitemap.episode.11.xml
+sitemap.episode.2.xml
+sitemap.episode.20.xml
+sitemap.episode.21.xml
+sitemap.episode.22.xml
+sitemap.episode.23.xml
+...
+```
+
+Using `sort -V` it sorts the lines numerically!
+
+Working example: 
+
+```shell
+$ aws s3 ls s3://cool-bucket | awk '{print $4}' | sort -V
+sitemap.brands.xml
+sitemap.xml
+sitemap.episode.0.xml
+sitemap.episode.1.xml
+sitemap.episode.2.xml
+sitemap.episode.3.xml
+sitemap.episode.4.xml
+sitemap.episode.5.xml
+sitemap.episode.6.xml
+sitemap.episode.7.xml
+...
+```
