Usage:
  snap refresh [refresh-OPTIONS] [<snap>...]

The refresh command updates the specified snaps, or all snaps in the system if
none are specified.

With no further options, the snaps are refreshed to the current revision of the
channel they're tracking, preserving their confinement options. All available
channels of a snap are listed in its 'snap info' output.

When --revision is used, a later refresh will typically undo the revision
override.

Hold (--hold) is used to postpone snap refresh updates for all snaps when no
snaps are specified, or for the specified snaps.

When no snaps are specified --hold is only effective on auto-refreshes and will
not block either general refresh requests from 'snap refresh' or specific snap
requests from 'snap refresh target-snap'.

When snaps are specified --hold is effective on both their auto-refreshes
and general refresh requests from 'snap refresh'. However, specific snap
requests from 'snap refresh target-snap' remain unblocked and will proceed.
