ZFS-DIFF(8)		    System Manager's Manual		   ZFS-DIFF(8)

NAME
       zfs-diff	-- show	difference between ZFS snapshots

SYNOPSIS
       zfs diff	[-FHth]	snapshot snapshot|filesystem

DESCRIPTION
       Display the difference between a	snapshot of a given filesystem and an-
       other snapshot of that filesystem from a	later time or the current con-
       tents  of  the  filesystem.  The	first column is	a character indicating
       the type	of change, the other columns indicate pathname,	 new  pathname
       (in  case  of  rename),	change in link count, and optionally file type
       and/or change time.  The	types of change	are:
	     -	The path has been removed
	     +	The path has been created
	     M	The path has been modified
	     R	The path has been renamed

       -F  Display an indication of the	type of	file, in a manner  similar  to
	   the -F option of ls(1).
	     B	Block device
	     C	Character device
	     /	Directory
	     >	Door
	     |	Named pipe
	     @	Symbolic link
	     P	Event port
	     =	Socket
	     F	Regular	file

       -H  Give	 more  parsable	tab-separated output, without header lines and
	   without arrows.

       -t  Display the path's inode change time	as the first column of output.

       -h  Do not \0ooo-escape non-ASCII paths.

EXAMPLES
   Example 1: Showing the differences between a	snapshot and a ZFS Dataset
       The following example shows how to see what has changed between a prior
       snapshot	of a ZFS dataset and its current state.	 The -F	option is used
       to indicate type	information for	the files affected.
	     # zfs diff	-F tank/test@before tank/test
	     M	     /	     /tank/test/
	     M	     F	     /tank/test/linked	    (+1)
	     R	     F	     /tank/test/oldname	-> /tank/test/newname
	     -	     F	     /tank/test/deleted
	     +	     F	     /tank/test/created
	     M	     F	     /tank/test/modified
