QUOT(8) BSD System Manager's Manual QUOT(8)
NAME
quot -- display disk space occupied by each user
SYNOPSIS
quot [-acfhknv] [filesystem ...]
DESCRIPTION
The quot utility is used to gather statistics about the disk usage for each local user.
The following options are available:
-a Include statistics for all mounted file systems.
-c Display three columns containing number of blocks per file, number of files in this category, and aggregate total of blocks in files
with this or lower size.
-f For each user, display count of files and space occupied.
-h Estimate the number of blocks in each file based on its size. Despite that this does not give the correct results (it does not
account for the holes in files), this option is not any faster and thus is discouraged.
-k Force the numbers to be reported in kilobyte counts. By default, all sizes are reported in 512-byte block counts.
-n Given a list of inodes (plus some optional data on each line) in the standard input, for each file print out the owner (plus the
remainder of the input line). This is traditionally used in the pipe:
ls -i | sed -e 's,^ *,,' | sort -k 1n | quot -n filesystem
to get a report of files and their owners.
-v In addition to the default output, display the number of files not accessed within 30, 60 and 90 days.
ENVIRONMENT
BLOCKSIZE If the environment variable BLOCKSIZE is set, and the -k option is not specified, the block counts will be displayed in units of
that size block.
SEE ALSO
df(1), quota(1), getmntinfo(3), fstab(5), mount(8)
HISTORY
This implementation of quot is by Wolfgang Solfrank / TooLs GmbH.
BUGS
ncheck (which would be a lot more useful than ls -i in the example above) does not exist in FreeBSD.
