edquota(8) System Manager's Manual edquota(8) NAME edquota - edits quotas SYNOPSIS /usr/sbin/edquota [-gGuU] -t /usr/sbin/edquota [-p proto_username] [-u] username ... /usr/sbin/edquota [-P proto_userID] -U userID ... /usr/sbin/edquota [-P proto_userID] [-u] username ... /usr/sbin/edquota [-p proto_username] -U userID ... /usr/sbin/edquota [-p proto_groupname] -g groupname ... /usr/sbin/edquota [-P proto_groupID] -G groupID ... /usr/sbin/edquota [-P proto_groupID] -g groupname ... /usr/sbin/edquota [-p proto_groupname] -G groupID ... PARAMETERS Specifies a prototypical user or group by the user name or group name. A prototypical user or group has previously-defined, valid quota files that you want to duplicate for other user or group quota files. Speci- fies a prototypical user or group by the user id or group id. A proto- typical user or group has previously-defined, valid quota files that you want to duplicate for other user or group quota files. FLAGS Edits the quotas of one or more groups, specified by groupname on the command line. When used with the -t flag, sets or changes the grace period for all file systems with group quotas specified in the /etc/fstab file. Edits the quotas of one or more groups, specified by groupID on the command line. When used with the -t flag, sets or changes the grace period for all file systems with group quotas speci- fied in the /etc/fstab file. Initializes the specified quotas by du- plicating the established quotas of the prototypical user's name (when used with the -u flag, the -U flag, or no other flags) or the prototyp- ical group's name (when used with the -g or -G flags). The proto_user- name or proto_groupname must have a valid quota file. Establishing quotas for one user or group and then using the -p flag to duplicate these quotas for other users is the normal mechanism for initializing quotas for a group of users. Initializes the specified quotas by du- plicating the established quotas of the prototypical user's id (when used with the -U flag or the -u flag) or the prototypical group's id (when used with the -G flag or the -g flag). The proto_userID or proto_groupID must have a valid quota file. Establishing quotas for one user or group and then using the -P flag to duplicate these quotas for other users is the normal mechanism for initializing quotas for a group of users. Sets or changes the default grace period for which users may exceed their soft limits. By default, or when you specify -t with the -u flag, the grace period is set for all file systems with user quotas specified in the /etc/fstab file. When you specify -t with the -g flag, the grace period is set for all of the file systems with group quotas specified in the /etc/fstab file. Edits the quotas of one or more users, specified by username ... on the command line. The -u flag is the default. The -u flag, used with the -t flag, changes the grace period for all file systems with user quotas specified in the /etc/fstab file. Edits the quotas of one or more users, specified by userID ... on the command line. The -U flag used with the -t flag, changes the grace period for all file systems with user quotas speci- fied in the /etc/fstab file. DESCRIPTION The edquota command is a quota editor that allows you to add and modify user and group quotas and modify file system quota grace periods. Use the quota command to display the existing quota information. Note that disk quotas are displayed as 1 kilobyte blocks. For each user or group specified, the edquota command creates a tempo- rary file with an ASCII representation of the current quotas for that user or group, then invokes an editor to allow you to modify the file. The vi editor is invoked by default. To override the default, specify a different editor for the EDITOR environment variable in your login file. Setting a hard limit to 0 (zero) indicates that no quota should be im- posed. Setting a hard limit to 1 (one) indicates that no allocations should be permitted. Setting a soft limit to 1 (one) with a hard limit of 0 (zero) indicates that allocations should be permitted on only a temporary basis (see the -t flag). The current usage information in the file is for informational purposes; only the hard and soft limits can be changed. For each file system, the edquota command creates a temporary file with an ASCII representation of the current grace period for that user or group, then invokes an editor to allow you to modify the grace period. The grace period may be specified in days, hours, minutes, or seconds. Setting a grace period to 0 (zero) indicates that the default grace pe- riod should be imposed. Setting a grace period to 1 second indicates that no grace period should be granted. When you exit the editor, edquota reads the temporary file and modifies the quota.user and quota.group files for the target file system to reflect the changes made. Changes in grace periods take effect immediately unless a grace period is currently in effect. For example, assume a user exceeds a soft limit and receives a grace period of 7 days. A subsequent change to a grace period of 1 day will not affect the user's already-invoked grace period, unless the user drops below the soft limit and exceeds it once again. The default grace period for a file system is specified in the quota.user and quota.group files for the target file system. RESTRICTIONS You can use the edquota command to edit only those file systems that are in the /etc/fstab file and have userquota and groupquota entries. You must be the root user to edit quotas. NOTES The term file system represents either a UFS file system or an AdvFS fileset. The hard limit of a quota is one more unit than will be allowed when the quota limit is active. The quota is up to, but not including, the limit. For example, if you set a hard limit of 10,000 disk blocks for each user account in a file system, an account reaches the hard limit when 9,999 disk blocks have been allocated. EXAMPLES To apply the existing quotas of the user named user1 to the user named user2: /usr/sbin/edquota -p user1 -u user2 To apply the existing quotas of the user named user1 to the user named user2, using the default: /usr/sbin/edquota -p user1 user2 To apply the existing quotas of the user with the user id 361 to the user with the user id 382: /usr/sbin/edquota -P 361 -U 382 To apply the existing quotas of the user named user1 to the user with the user id 382: /usr/sbin/edquota -p user1 -U 382 FILES Specifies the command path Contains user quotas for file systems Con- tains group quotas for file systems Contains file system names and lo- cations RELATED INFORMATION quota(1), quotacheck(8), quotaon(8), quotactl(2), fstab(4). delim off edquota(8)
