options to display the delta between two different points in time.
This may not be used with the
interval or count
options of the
iostat
sub-command.
- -S sincefile, --since sincefile
-
Show difference between current stats and those in
sincefile
. sincefile
must be in the same format as
/proc/self/mountstats.
This may be used with the
-f|--file
options to display the delta between two different points in time.

options of the

sub-command.
Options specific to the mountstats sub-command
-n, --nfs
