39 .Nd file system quota consistency checker
50 utility examines each file system,
51 builds a table of current disk usage,
52 and compares this table against that recorded
53 in the disk quota file for the file system.
54 If any inconsistencies are detected, both the
55 quota file and the current system copy of the
56 incorrect quotas are updated (the latter only
57 occurs if an active file system is checked).
58 By default both user and group quotas are checked.
60 The following options are available:
