README

===========================
====     quotatool     ====
===========================

Quick Start
===========

    ./configure
    make
    sudo make install


Usage
=====

    quotatool { -u uid | -g gid } [ options ... ] filesystem
    quotatool { -u uid | -g gid } -t time { -i | -b } filesystem
    quotatool { -u uid | -g gid } -r filesystem
    quotatool { -u uid | -g gid } -d filesystem

The actual arguments accepted depends on your system.  Solaris,
for example, doesn't support group quotas, so the -g option is
useless.   If your getopt() doesn't support optional arguments,
then you always need to pass an argument to -u and -g.


Arguments and Options
=====================

   -u uid  username or uid. 
   -g gid  groupname or gid. 
      	   See examples below how to handle non-existent uid/gid

   -b      set block limits
   -i      set inode limits

   -q n    set soft limit to n blocks/inodes
   -l n    set hard limit to n blocks/inodes

   quotatool accepts the units Kb, Mb, Gb, Tb, bytes and blocks
   to modify limit arguments. 
   Use +/- to raise/lower quota by the specified amount.
   See examples below.

   -R      Raise only - makes sure you don't accidentally lower quotas for a user/group

   -t      time set global grace period to time.
           The time parameter consists of an optional
           '+' or '-' modifier, a  number, and one of: 
           'sec', 'min', 'hour', 'day', 'week', and 
           'month'.  If a +/- modifier is present, the
           current quota will be increased/reduced by
           the amount specified

   -r      restart grace period for uid or gid

   -h      print a usage message

   -v      verbose mode -- print status messages during execution
           use this twice for even more information

   -n      do everything except set the quota.  useful with -v
           to see what is supposed to happen

   -V      show version

   filesystem is either device name (eg /dev/sda1) or mountpoint (eg /home)

Examples
========

Set soft block limit to 800Mb, hard block limit to 1Gb for user mpg4 on /home:

   quotatool -u mpg4 -b -q 500M -l 1G /home

Raise soft block limit by 100M for non-existent gid 12345 on /dev/loop3:

   quotatool -g :12345 -b -q +100M /dev/loop3

Set hard inode limit to 2000 for user johan on /var:

   quotatool -u johan -i -l 2000 /var

Set the global block grace period to one week on /home:

   quotatool -u  -b -t "1 week" /home
   
Restart inode grace period for user johan on root filesystem:

   quotatool -u johan -i -r /


Notes
=====

* Grace periods are set on a "global per quotatype and filesystem" basis only.
Each quotatype (usrquota / grpquota) on each filesystem has two grace periods
- one for block limits and one for inode limits.
It is not possible to set different grace periods for users on the same filesystem.

* Using non-existent uids/gids like ":12345" can be useful when configuring quotas on
a mounted filesystem which is a separate system in it self, like when preparing an
install image or repairing a filesystem from another installation.

* Limit arguments can be specified in several ways, these are all equivalent:
  1M
  1m
  1Mb
  1 "Mb"

* Use +/- to raise/lower quotas relative to current limits

* Use -v (or -v -v) to see verbose/debug info when running commands

Platforms and Filesystems
=========================

quotatool currently builds and works well on:

-- Linux --
Both old and new quota formats. 
ext2, ext3, ext4, ReiserFS and XFS supported

-- Solaris --

-- AIX --
