+# Show The Size Of Everything In A Directory
+
+The `ls` command will list everything in a given directory.  The `du`
+command is used to display disk usage statistics -- with the `-sh` flag, it
+will display the file size in a human readable format.
+
+We can combine these two commands with `xargs` to get a listing of the sizes
+of everything in a directory.
+
+```
+ls | xargs du -sh
+```
+
+See `man du` and `man xargs` for more details.
