quotatool - manipulate filesystem quotas

quotatool [-u uid | -g gid] [-b | -i] [-r | -l NUM | -q NUM] [-nvR] [-d] filesystem

quotatool -u | -g -t TIME [-nv] filesystem

quotatool [-hV]

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.

-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.

-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"

-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: "MB", "kB", "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

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

quota.user , quota.group (linux)

quotas (solaris, ...)

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.
