55: .SH DESCRIPTION
56: .I Edquota
57: is a quota editor.
58: By default, or if the \fI-u\fP flag is specified,
59: one or more users may be specified on the command line.
60: For each user a temporary file is created
61: with an ASCII representation of the current
62: disk quotas for that user.
63: The list of filesystems with user quotas is determined from
64: .IR /etc/fstab .
65: An editor is invoked on the ASCII file.
66: The editor invoked is
67: .IR vi (1)
68: unless the environment variable EDITOR specifies otherwise.
69: .PP
70: The quotas may then be modified, new quotas added, etc.
71: Setting a quota to zero indicates that no quota should be imposed.
72: Setting a hard limit to one indicates that no allocations should
73: be permitted.
74: Setting a soft limit to one with a hard limit of zero
75: indicates that allocations should be permitted on
76: only a temporary basis (see \fI-t\fP below).
77: The current usage information in the file is for informational purposes;
78: only the hard and soft limits can be changed.
79: .PP
80: On leaving the editor,
81: .I edquota
82: reads the temporary file and modifies the binary
83: quota files to reflect the changes made.
84: .PP
85: If the
86: .B \-p
87: option is specified,
88: .I edquota
89: will duplicate the quotas of the prototypical user
90: specified for each user specified.
91: This is the normal mechanism used to
92: initialize quotas for groups of users.
93: .PP
94: If the \fI-g\fP flag is specified,
95: .I edquota
96: is invoked to edit the quotas of
97: one or more groups specified on the command line.
98: The \fI-p\fP flag can be specified in conjunction with
99: the \fI-g\fP flag to specify a prototypical group
100: to be duplicated among the listed set of groups.
101: .PP
102: Users are permitted to exceed their soft limits
103: for a grace period that may be specified per filesystem.
104: Once the grace period has expired,
105: the soft limit is enforced as a hard limit.
106: The default grace period for a filesystem is specified in
107: .IR /usr/include/ufs/quota.h .
108: The \fi-t\fP flag can be used to change the grace period.
109: By default, or when invoked with the \fI-u\fP flag,
110: the grace period is set for all the filesystems with user
111: quotas specified in
112: .IR /etc/fstab .
113: When invoked with the \fI-g\fP flag the grace period is
114: set for all the filesystems with group quotas specified in
115: .IR /etc/fstab .
116: The grace period may be specified in days, hours, minutes, or seconds.
117: Setting a grace period to zero indicates that the default
118: grace period should be imposed.
119: Setting a grace period to one second indicates that no
120: grace period should be granted.
121: .PP
122: Only the super-user may edit quotas.
