+% btrfs-size.pl
+
+_2016-08-16_ - btrfs-size.pl is a quick little script to provide an overview of
+the disk space used by btrfs subvolumes. It's comparable to
+[btrfs-size.sh](https://poisonpacket.wordpress.com/2015/05/26/btrfs-snapshot-size-disk-usage/),
+but is somewhat faster and has a few options to sort the output.
+
+Honestly, it's still hard to draw any conclusions from the sizes provided by
+btrfs, but sadly, [ncdu](/ncdu) is useless for snapshot-heavy filesystems.
+
+Only tested with btrfs-progs v4.4.1.

+
+## Usage
+
+    btrfs-size.pl --help [-nser] <path>
+      -n  Order by path name
+      -s  Order by (total) subvolume size
+      -e  Order by exclusive subvolume size
+      -r  Reverse order
