+## containers-storage-dedup 1 "November 2024"
+
+## NAME
+containers-storage dedup - Deduplicate similar files in the images
+
+## SYNOPSIS
+**containers-storage** **dedup**
+
+## DESCRIPTION
+Find similar files in the images and deduplicate them.  It requires reflink support from the file system.
+
+## OPTIONS
+**--hash-method** *method*
+
+Specify the function to use to calculate the hash for a file.  It can be one of: *size*, *crc*, *sha256sum*.
+
+## EXAMPLE
+**containers-storage dedup**
