684 To make the "zfs list" output more script-friendly, you can suppress the
685 output of the headers for each column by passing the -H parameter:

689 Another helpful option for script writers is -p, which displays the numbers
690 in non-rounded, exact values:

760 You can prevent the removal of a ZFS snapshot by using the hold subcommand.

772 hold was created, not the snapshot it holds. The "zfs destroy" command will
773 echo a "dataset is busy" message on the console when it encounters a hold.
