74 .Sh DESCRIPTION
75 .Nm Edquota
76 is a quota editor.
77 By default, or if the
78 .Fl u
79 flag is specified,
80 one or more users may be specified on the command line.
81 For each user a temporary file is created
82 with an
83 .Tn ASCII
84 representation of the current
85 disk quotas for that user.
86 The list of filesystems with user quotas is determined from
87 .Pa /etc/fstab .
88 An editor is invoked on the
89 .Tn ASCII
90 file.
91 The editor invoked is
92 .Xr vi 1
93 unless the environment variable
94 .Ev EDITOR
95 specifies otherwise.
96 .Pp
97 The quotas may then be modified, new quotas added, etc.
98 Setting a quota to zero indicates that no quota should be imposed.
99 Setting a hard limit to one indicates that no allocations should
100 be permitted.
101 Setting a soft limit to one with a hard limit of zero
102 indicates that allocations should be permitted only on
103 a temporary basis (see
104 .Fl t
105 below).
106 The current usage information in the file is for informational purposes;
107 only the hard and soft limits can be changed.
108 .Pp
109 On leaving the editor,
110 .Nm
111 reads the temporary file and modifies the binary
112 quota files to reflect the changes made.
113 .Pp
114 If the
115 .Fl p
116 option is specified,
117 .Nm
118 will duplicate the quotas of the prototypical user
119 specified for each user specified.
120 This is the normal mechanism used to
121 initialize quotas for groups of users.
122 If the user given to assign quotas to is a numerical uid
123 range (e.g. 1000-2000), then
124 .Nm
125 will duplicate the quotas of the prototypical user
126 for each uid in the range specified. This allows
127 for easy setup of default quotas for a group of users.
128 The uids in question do not have to be currently assigned in
129 .Pa /etc/passwd .
130 .Pp
131 If one or more
132 .Fl e Ar fspath Ns Op : Ns Ar bslim Ns Op : Ns Ar bhlim Ns Op : Ns Ar islim Ns Op : Ns Ar ihlim
133 options are specified,
134 .Nm
135 will non-interactively set quotas defined by
136 .Ar bslim ,
137 .Ar bhlim ,
138 .Ar islim and
139 .Ar ihlim
140 on each particular filesystem referenced by
141 .Ar fspath .
142 Here
143 .Ar bslim
144 is soft limit on number of blocks,
145 .Ar bslim
146 is hard limit on number of blocks,
147 .Ar islim
148 is soft limit on number of files and
149 .Ar ihlim
150 is hard limit on number of files.
151 If any of the
152 .Ar bslim ,
153 .Ar bhlim ,
154 .Ar islim and
155 .Ar ihlim
156 values are omitted, it is assumed to be zero, therefore
157 indicating that no quota should be imposed.
158 .Pp
159 If invoked with the
160 .Fl f
161 option,
162 .Nm
163 will read and modify quotas on the filesystem specified by
164 .Ar fspath
165 only.
166 The
167 .Ar fspath
168 argument may be either a special device
169 or a filesystem mount point.
170 The primary purpose of this option is to set the scope for the
171 .Fl p
172 option, which would overwrite quota records on every
173 filesystem with quotas otherwise.
174 .Pp
175 If the
176 .Fl g
177 flag is specified,
178 .Nm
179 is invoked to edit the quotas of
180 one or more groups specified on the command line.
181 The
182 .Fl p
183 flag can be specified in conjunction with
184 the
185 .Fl g
186 flag to specify a prototypical group
187 to be duplicated among the listed set of groups.
188 Similarly,
189 .Fl e
190 flag can be specified in conjunction with
191 the
192 .Fl g
193 flag to non-interactively set-up quotas on the listed set
194 of groups.
195 .Pp
196 Users are permitted to exceed their soft limits
197 for a grace period that may be specified per filesystem.
198 Once the grace period has expired,
199 the soft limit is enforced as a hard limit.
200 The default grace period for a filesystem is specified in
201 .In vfs/ufs/quota.h .
202 The
203 .Fl t
204 flag can be used to change the grace period.
205 By default, or when invoked with the
206 .Fl u
207 flag,
208 the grace period is set for all the filesystems with user
209 quotas specified in
210 .Pa /etc/fstab .
211 When invoked with the
212 .Fl g
213 flag the grace period is
214 set for all the filesystems with group quotas specified in
215 .Pa /etc/fstab .
216 The grace period may be specified in days, hours, minutes, or seconds.
217 Setting a grace period to zero indicates that the default
218 grace period should be imposed.
219 Setting a grace period to one second indicates that no
220 grace period should be granted.
221 .Pp
222 Only the super-user may edit quotas.
