NAME

       quotatool - manipulate filesystem quotas

SYNOPSIS

       quotatool [-u [:]uid | -g [:]gid] [-b | -i] [-r | -l NUM | -q NUM] [-nvR] [-d] filesystem
       quotatool (-u | -g) (-b | -i) -t TIME [-nv] filesystem
       quotatool [-hV]

DESCRIPTION

       quotatool  is  a  tool  for  manipulating filesystem quotas.  Depending on the commandline
       options given, it can set hard or soft limits on block and  inode  usage,  set  and  reset
       grace  periods,  for both users and (if your system supports this) groups.  The filesystem
       to set the quota on is given as the first (and only) non-option element, and it is  either
       the block special file (i.e /dev/sda3) or the mount point (i.e. /home) for the filesystem.

OPTIONS

       -u [[:]uid]
              Set user quotas

       -g [[:]gid]
              Set group quotas

       uid  and  gid  are  either  the  numerical  ID  of  the  user or group, or its name in the
       /etc/passwd and /etc/group files. Prefix : allows using numerical uid/gid not  present  in
       /etc/passwd or /etc/group.

       -b     Set block quotas [default]

       -i     Set inode quotas

       The -b and -i  options are persistent -- they stay in effect until they are overridden.

       -R     Only  raise quotas, never lower. Makes sure you don't accidentally lower quotas for
              a user/group.

       -t TIME
              Set the system-wide grace period to TIME.  TIME consists of an optional '-' or  '+'
              character,  a  number,  and  optionally  one of the following modifiers: "seconds",
              "minutes", "hours", "days", "weeks", or "months".  Unique abbreviations (e.g.  "s",
              "mo") are also accepted. The default is "seconds".  The argument should be preceded
              by -u|-g and -b|-i

       -r     Reset the grace period

       -l NUM Set hard limit to NUM

       -q NUM Set soft limit (quota) to NUM

       NUM consists of an optional '-' or '+' character, a number,  and  optionally  one  of  the
       following  modifiers:  "Kb", "Mb", "Gb", "Tb", "bytes", or "blocks".  Unique abbreviations
       are also accepted.  The default is "blocks"

       If +/- is supplied, the existing quota is increased or reduced by the specified amount.

       -d     Dump quota info for user/group in a machine readable format:

                                 |------- BLOCKS --------| |-------- FILES --------|
              uid/gid mountpoint current quota limit grace current quota limit grace

              grace is the number of seconds from now until the grace time ends. May be  negative
              = time already passed. When quota is not passed, grace is zero.

       -n     dry-run:  show  what  would have been done but don't change anything.  Use together
              with -v

       -v     Verbose output. Use twice or thrice for even more output (debugging)

       -h     Print a usage message to stdout and exit successfully

       -V     Print version information to stdout and exit successfully

FILESYSTEMS / FORMATS

       On Linux, quotatool works with both "old" and "new" + "generic" kernel-quota  formats  and
       also has support for quotas on XFS.

FILES

       quota.user , quota.group (linux)
       quotas (solaris, ...)

BUGS

       Calling  quotatool  with  more  than  one -v option will cause a segfault on some systems.
       This will happen if vprintf (3) fails to check for NULL arguments.  GNU libc doesn't  have
       this problem, solaris libc does.
