EDQUOTA(8)		  BSD System Manager's Manual		    EDQUOTA(8)

NAME
     edquota - edit user quotas

SYNOPSIS
     edquota [-u] [-p proto-username] username ...
     edquota -g [-p proto-groupname] groupname ...
     edquota -t [-u]
     edquota -t -g

DESCRIPTION
     Edquota is a quota editor used to edit the user and group disk quotas.

     Options:

     -g	     Edit the quotas for the groups specified on the command line.

     -u	     Edit the quotas for the specified users specified on the command
	     line.  This flag is optional and is the default if -g and -t are
	     not specified.

     -p proto-username
     -p proto-groupname
	     When used with the -u or -g flags, the quotas for the specified
	     prototype user or prototype group will be used to initialize the
	     quotas for the specified users and groups.	 The editor will not
	     be invoked.  This is the normal mechanism used to initialize quo-
	     tas for a number of users or groups.

     -t	     Edit the per-filesystem user and group grace periods.  When -g is
	     specified, edit the group grace periods.  If -u or no flags are
	     specified, edit the user grace periods.

   Editing quotas

     By default, or if the -u flag is specified, one or more users may be
     specified on the command line.  For each user a temporary file is created
     with an ASCII representation of the current disk quotas for that user.
     The list of filesystems with user quotas is determined from /etc/fstab.
     An editor is invoked on the ASCII file.  The editor invoked is vi(1) un-
     less the environment variable EDITOR specifies otherwise.

     The quotas may then be modified, new quotas added, etc.  Setting a quota
     to zero indicates that no quota should be imposed.	 Setting a hard limit
     to one indicates that no allocations should be permitted.	Setting a soft
     limit to one with a hard limit of zero indicates that allocations should
     be permitted on only a temporary basis (see -t below).  The current usage
     information in the file is for informational purposes; only the hard and
     soft limits can be changed.

     On leaving the editor, edquota reads the temporary file and modifies the
     binary quota files to reflect the changes made.

     If the -g flag is specified, edquota is invoked to edit the quotas of one
     or more groups specified on the command line.

   Initializing quotas from prototypes

     The -p flag may be specified with the -u (or -g) flag to specify a proto-
     type user (or group) to be used to initialize the quotas for the speci-
     fied user(s) (or group(s)). This facilitates initializing the quotas for
     many users and groups at once, or automating the initialization of quo-
     tas.

     The editor is not invoked when initializing quotas from a prototype.

   Grace periods

     Users are permitted to exceed their soft limits for a grace period that
     may be specified per filesystem.  Once the grace period has expired, the
     soft limit is enforced as a hard limit.  The default grace period for a
     filesystem is specified in /usr/include/ufs/ufs/quota.h.

     The -t flag can be used to change the grace period.  By default, or when
     invoked with the -u flag, the grace period is set for all the filesystems
     with user quotas specified in /etc/fstab. When invoked with the -g flag
     the grace period is set for all the filesystems with group quotas speci-
     fied in /etc/fstab. The grace period may be specified in days, hours,
     minutes, or seconds.  Setting a grace period to zero indicates that the
     default grace period should be imposed.  Setting a grace period to one
     second indicates that no grace period should be granted.

     Users or groups already operating within a grace period will not be af-
     fected when a new grace period is set for a filesystem until their usage
     drops below the soft limit.  This can be precipitated by momentarily in-
     creasing the soft limit.

     Only the super-user may edit quotas.

FILES
     quota.user		       at the filesystem root with user quotas
     quota.group	       at the filesystem root with group quotas
     /etc/fstab		       to find filesystem names and locations

DIAGNOSTICS
     Various messages about inaccessible files; self-explanatory.
