.Sh SYNOPSIS
 | 
						|
.Nm zfs
 | 
						|
.Cm clone
 | 
						|
.Op Fl p

.Sh DESCRIPTION
 | 
						|
See the
 | 
						|
.Sx Clones
 | 
						|
section of
 | 
						|
.Xr zfsconcepts 7
 | 
						|
for details.
 | 
						|
The target dataset can be located anywhere in the ZFS hierarchy,
 | 
						|
and is created as the same type as the original.
 | 
						|
.Bl -tag -width Ds
 | 
						|
.It Fl o Ar property Ns = Ns Ar value
 | 
						|
Sets the specified property; see
 | 
						|
.Nm zfs Cm create
 | 
						|
for details.
 | 
						|
.It Fl p
 | 
						|
Creates all the non-existing parent datasets.
 | 
						|
Datasets created in this manner are automatically mounted according to the
 | 
						|
.Sy mountpoint
 | 
						|
property inherited from their parent.
 | 
						|
If the target filesystem or volume already exists, the operation completes
 | 
						|
successfully.

.Sh EXAMPLES
 | 
						|
.\" These are, respectively, examples 9, 10 from zfs.8
 | 
						|
.\" Make sure to update them bidirectionally
 | 
						|
.Ss Example 1 : No Creating a ZFS Clone
 | 
						|
The following command creates a writable file system whose initial contents are
 | 
						|
the same as
 | 
						|
.Ar pool/home/bob@yesterday .
 | 
						|
.Dl # Nm zfs Cm clone Ar pool/home/bob@yesterday pool/clone
 | 
						|
.
 | 
						|
.Ss Example 2 : No Promoting a ZFS Clone
 | 
						|
The following commands illustrate how to test out changes to a file system, and
 | 
						|
then replace the original file system with the changed one, using clones, clone
 | 
						|
promotion, and renaming:
 | 
						|
.Bd -literal -compact -offset Ds
 | 
						|
.No # Nm zfs Cm create Ar pool/project/production
 | 
						|
  populate /pool/project/production with data
 | 
						|
.No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today
 | 
						|
.No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta
 | 
						|
  make changes to /pool/project/beta and test them
 | 
						|
.No # Nm zfs Cm promote Ar pool/project/beta
 | 
						|
.No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy
 | 
						|
.No # Nm zfs Cm rename Ar pool/project/beta pool/project/production
 | 
						|
  once the legacy version is no longer needed, it can be destroyed
 | 
						|
.No # Nm zfs Cm destroy Ar pool/project/legacy
