warnquota - send mail to users over quota


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


warnquota checks the disk quota for specified local filesystems (or for each local filesystem if none specified) and mails a warning message to those users who have reached their softlimit. It is typically run via cron(8). -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 Use quotatab instead of /etc/quotatab as file with device description strings (see quotatab(5) for syntax). -c, --config=configfile Use configfile instead of /etc/warnquota.conf as configuration file (see warn‐ quota.conf(5) for syntax). -a, --admins-file=adminsfile Use adminsfile instead of /etc/quotagrpadmins as a file with administrators of the groups (see quotagrpadmins(5) for syntax). -u, --user check whether users are not exceeding quotas (default). -g, --group check whether groups are not exceeding quotas. If group is exceeding quota a mail is sent to the user specified in /etc/quotagrpadmins. -s, --human-readable Try to report used space, number of used inodes and limits in more appropriate units than the default ones. -i, --no-autofs ignore mountpoints mounted by automounter. -d, --no-details do not attach quota report in email.
