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 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

     -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
