warnquota [ -ugsid ] [ -F quotaformat ] [ -q quotatab ] [ -c configfile ] [ -a adminsfile ]

-F, --format=quotaformat
Perform setting for specified format (ie. don't perform format autodetection). Possible format names are: vfsold Original quota format with 16-bit UIDs / GIDs, vfsv0 Quota format with 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
