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.  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 by scanning the mounted filesystems for a .quota.ops.user file
     located at its root.  An editor is invoked on the ASCII file.  The editor invoked is vi(1)
     unless 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.  The binary quota file, .quota.user is stored at the root of
     the filesystem.  The default filename and root location for the user quotas cannot be over-
     ridden.

     If the -p flag is specified, edquota will duplicate the quotas of the prototypical user
     specified for each user specified.  This is the normal mechanism used to initialize quotas
     for groups of users.

     If the -g flag is specified, edquota is invoked to edit the quotas of one or more groups
     specified on the command line.  The list of filesystems with group quotas is determined by
     scanning the mounted filesystems for a .quota.ops.group file located at its root.	Simi-
     larly, the binary quota file, .quota.group is stored at the root of the filesystem.  The
     default filename and root location for group quotas cannot be overridden.	The -p flag can
     be specified in conjunction with the -g flag to specify a prototypical group to be dupli-
     cated among the listed set of groups.

     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/sys/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 each filesystem with a .quota.ops.user file located at its root.
     When invoked with the -g flag, the grace period is set for each filesystem with a
     .quota.ops.group file located at its root.  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.

     Only the super-user may edit quotas.

FILES
     Each of the following quota files is located at the root of the mounted filesystem.  The
     mount option files are empty files whose existence indicates that quotas are to be enabled
     for that filesystem.  The binary data files will be created by edquota, if they don't
     already exist.

     .quota.user       data file containing user quotas
     .quota.group      data file containing group quotas
     .quota.ops.user   mount option file used to enable user quotas
     .quota.ops.group  mount option file used to enable group quotas
