quota(1M)						  System Administration Commands						 quota(1M)

NAME
quota - display a user's ufs file system disk quota and usage SYNOPSIS
quota [-v] [username] DESCRIPTION
quota displays users' ufs disk usage and limits. Only the super-user may use the optional username argument to view the limits of other users. quota without options only display warnings about mounted file systems where usage is over quota. Remotely mounted file systems which do not have quotas turned on are ignored. username can be the numeric UID of a user. OPTIONS
-v Display user's quota on all mounted file systems where quotas exist. USAGE
See largefile(5) for the description of the behavior of quota when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes). FILES
/etc/mnttab list of currently mounted filesystems ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
edquota(1M), quotaon(1M), quotacheck(1M), repquota(1M), rquotad(1M), attributes(5), largefile(5) NOTES
quota will also display quotas for NFS mounted ufs-based file systems if the rquotad daemon is running. See rquotad(1M). quota may display entries for the same file system multiple times for multiple mount points. For example, quota -v user1 may display identical quota information for user1 at the mount points /home/user1, /home/user2, and /home/user, if all three mount points are mounted from the same file system with quotas turned on.
