zfs-diff — Display the difference between two snapshots of a given filesystem.

zfs diff [-FHt] snapshot snapshot|filesystem

zfs diff [-FHt] snapshot snapshot|filesystem
Display the difference between a snapshot of a given filesystem and another snapshot of that filesystem from a later time or the current contents 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
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
Give more parsable tab-separated output, without header lines and without arrows.
Display the path's inode change time as the first column of output.
