+SYNOPSIS:
+   duplicacy diff - Compare two snapshots or two revisions of a file
+
+USAGE:
+   duplicacy diff [command options] [<file>]
+
+OPTIONS:
+   -id <snapshot id>        diff with the snapshot with the specified id
+   -r <revision> [+]        the revision number of the snapshot
+   -hash                    compute the hashes of on-disk files
+   -storage <storage name>  retrieve files from the specified storage
+```
+The *diff* command compares the same file in two different snapshots if a file is given, otherwise compares the two snapshots.
+
+The file must be specified with a path relative to the repository.
+
+You can specify a different snapshot id rather than the default snapshot id.
+
+If only one revision is given by `-r`, the right hand side of the comparison will be the on-disk file.  The `-hash` option can then instruct this command to compute the hash of the file.
+
+You can use the `-storage` option to select a different storage other than the default one.
