       typically run via cron(8).

              32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode usage and
              limits, vfsv1 Quota format with 64-bit quota limits and usage,
              xfs Quota on XFS filesystem.

       -q, --quota-tab=quotatab
              Use quotatab instead of /etc/quotatab as file with device

              also specified explicitely by an optional argument in format [
              kgt ],[ kgt ] where the first character specifies space units
              and the second character specifies inode units.

       -i, --no-autofs
