功能说明：显示磁盘已使用的空间与限制。
语法：quota[-quvV][用户名称...]或quota[-gqvV][群组名称...]
补充说明：执行quota指令，可查询磁盘空间的限制，并得知已使用多少空间。
参数：
-g列出群组的磁盘空间限制。
-q简明列表，只列出超过限制的部分。
-u列出用户的磁盘空间限制。
-v显示该用户或群组，在所有挂入系统的存储设备的空间限制。
-V显示版本信息。

NAME
quota - display disk usage and limits
SYNOPSIS
quota [ -F format-name ] [ -guvsil | q ]
quota [ -F format-name ] [ -uvsil | q ] user...
quota [ -F format-name ] [ -gvsil | q ] group...
DESCRIPTION
quota displays users' disk usage and limits. By default only the user quotas are printed.
quota reports the quotas of all the filesystems listed in /etc/mtab. For filesystems that are NFS-mounted a call to the rpc.rquotad on the server machine is performed to get the information.
OPTIONS
- -F format-name
- Show quota for specified format (ie. don't perform format autodetection). Possible format names are: vfsold (version 1 quota), vfsv0 (version 2 quota), rpc (quota over NFS), xfs (quota on XFS filesystem)
- -g
- Print group quotas for the group of which the user is a member. The optional group argument(s) restricts the display to the specified group(s).
- -u
- flag is equivalent to the default.
- -v
- will display quotas on filesystems where no storage is allocated.
- -s
- option will make quota(1) try to choose units for showing limits, used space and used inodes.
- -i
- ignore mountpoints mounted by automounter
- -l
- report quotas only on local filesystems (ie. ignore NFS mounted filesystems).
- -q
- Print a more terse message, containing only information on filesystems where usage is over quota.
- -Q
- Do not print error message if connection to rpc.rquotad is refused (usually this happens when rpc.rquotad is not running on the server).
Specifying both -g and -u displays both the user quotas and the group quotas (for the user).
Only the super-user may use the -u flag and the optional user argument to view the limits of other users. Non-super-users can use the the -g flag and optional group argument to view only the limits of groups of which they are members.
The -q flag takes precedence over the -v flag.
DIAGNOSTICS
If quota exits with a non-zero status, one or more filesystems are over quota.
FILES
- aquota.user or aquota.group
- quota file at the filesystem root (version 2 quota, non-XFS filesystems)
- quota.user or quota.group
- quota file at the filesystem root (version 1 quota, non-XFS filesystems)
- /etc/mtab
- default filesystems
