parted: align-check
2.4.1 align-check
-----------------
-- Command: align-check ALIGN-TYPE N
Determine whether the starting sector of partition N meets the
disk's selected alignment criteria. ALIGN-TYPE must be 'minimal',
'optimal' or an abbreviation. When in script mode, if the
partition does not meet the alignment requirement, exit with status
1; otherwise (including on older kernels for which alignment data
is not available), continue processing any remaining commands.
Without '--script', print either 'N aligned' or 'N not aligned'.
Example:
(parted) align-check minimal 1
1 aligned
