Apparently my OS is new enough (b 147 <openindiana>)... since the command is known. Very nice... but where is the documentation? `man zfs' has no hits on a grep for diff (except different..) Ahh never mind... I found: http://www.c0t0d0s0.org/archives/6829-zfs-diff-in-Opensolaris.html Which tells all about it but apparently too new to be in the man page yet? The date there is Aug of 2010... thats kind of a good while ago. The ones with `+' are added... and a very nice way to get such a list. But I also see a massive list of files with a letter `m' prefixed on each line, Which is supposed to mean modified, They cannot all really be modified so I'm thinking its something to do with rsyncing files from a windows XP machine to Openindiana.. is that likely? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
