     quotacheck	-- file	system quota consistency checker

     quotacheck	[-g] [-u] [-v] filesystem file ...
     quotacheck	[-g] [-u] [-v] -a

     The quotacheck utility examines each file system, builds a	table of cur-
     rent disk usage, and compares this	table against that recorded in the
     disk quota	file for the file system.  If any inconsistencies are de-
     tected, both the quota file and the current system	copy of	the incorrect
     quotas are	updated	(the latter only occurs	if an active file system is
     checked).	By default both	user and group quotas are checked.

     The following options are available:

     -a	     If	supplied in place of any file system names, quotacheck will
	     check all the file	systems	indicated in /etc/fstab	to be read-
	     write with	disk quotas.  By default only the types	of quotas
	     listed in /etc/fstab are checked.

     -g	     Only group	quotas listed in /etc/fstab are	to be checked.

     -u	     Only user quotas listed in	/etc/fstab are to be checked.

     -v	     Report discrepancies between the calculated and recorded disk
	     quotas and	other additional diagnostic messages.

     Specifying	both -g	and -u is equivalent to	the default.  Parallel passes
     are run on	the file systems required, using the pass numbers in
     /etc/fstab	in an identical	fashion	to fsck(8).

     Normally, quotacheck operates silently.

     The quotacheck utility expects each file system to	be checked to have a
     quota files named quota.user and which	are located at the
     root of the associated file system.  These	defaults may be	overridden in
     /etc/fstab.  If a file is not present, quotacheck will create it.	These
     files should be edited with the edquota(8)	utility.

     The quotacheck utility is normally	run at boot time from the /etc/rc
     file.  The	rc startup procedure is	controlled by the /etc/rc.conf vari-
     able check_quotas.	 Note that to enable this functionality	in /etc/rc you
     also need to enable startup quota procedures with the variable
     enable_quotas in /etc/rc.conf.

     The quotacheck utility accesses the raw device in calculating the actual
     disk usage	for each user.	Thus, the file systems checked should be qui-
     escent while quotacheck is	running.

     quota.user	  at the file system root with user quotas  at the file system root with group quotas
     /etc/fstab	  default file systems

     quota(1), quotactl(2), fstab(5), edquota(8), fsck(8), quotaon(8),

     The quotacheck utility appeared in	4.2BSD.
