NAME
qu - display quota usage statistics
SYNOPSIS
qu [--options] [directory ...]
DESCRIPTION
qu utility displays the file system block usage for each directory in the file hierarchy rooted in each directory argument. If no directory is specified, the block usage of the hierarchy rooted in the current directory usage is displayed. Usage is only calculated for files and directories owned by the process owner (i.e., you), making this useful for calculating real quota usage (hence qu).
You may view statistics for multiple, disjointed file hierarchies by specifying multiple directory arguments. You may also specify a variety of command-line arguments to alter the output of qu. See "OPTIONS".
OPTIONS
A variety of useful options are available for qu, allowing you to customize how qu calculates its disk usage and how that information is displayed.
Options may be specified with a single dash or the recommended GNU-style double-dash for clarity. Options may be abbreviated to the fewest unique letters required to avoid ambiguity:
qu -bl 512 -by -c /usr/local
and:
qu --bl=512 --by --c /usr/local
are the same as:
qu --blocksize=512 --bytes --cumulative /usr/local
Pay attention that as new options are added to qu, more characters may be required to avoid ambiguity.
- help
-
Show a brief help menu for qu and exit.
- version
-
Display the version number of qu and exit.
- verbose
-
Show far more information than you really want ;o). This is useful if you suspect that qu has a bug and want to be able to trace it somewhat. Seldom useful for the average user.
- blocksize=n
-
Use n when calculating block sizes. The default value of n is 1024 bytes so that qu will match the output of the 'quota' system command. If you want 'du'-style 512 byte block reporting, set blocksize to 512.
- bytes
-
Display total bytes used in the summary report. Because of the layout of the UNIX filesystem, actual disk usage is rounded up to the nearest block (512 bytes). So, for example, a file that is 513 bytes long will actually occupy two blocks of 512 bytes each or 1024 real bytes.
- cumulative
-
Displays the total disk usage for each directory of all blocks rooted in that directory. This is the default 'du'-style usage.
- levels=n
-
Show n levels of directories. Not specifying any number (or specifying 0) will show all directory levels. If the summary option is specified, no directory output will be displayed regardless of what levels is set to.
- sort=sortoption
-
Sorts the resulting directory data. If the summary option is specified, no directory output will be displayed regardless of what sort is set to. Valid sort options follow.
- alpha
-
Sort by directory alphanumerically
- alpha_i
-
Like alpha but case-insensitive
- alpha_reverse
-
Like alpha but reversed
- alpha_reverse_i
-
Like alpha_reverse but case-insensitive
- alpha_breadth
-
Sort by how "far" the directory is from the root, with the "closest" directories first in alphanumeric order
- alpha_breadth_i
-
Like alpha_breadth but case-insensitive
- blocks
-
Sort by block usage
- blocks_reverse
-
Like blocks but reversed. This is a useful sort option ;o)
EXAMPLES
Show brief statistics for the file hierarchy rooted in the current working directory
qu --summary
Show brief statistics for my home directory (should be close to 'quota -v' output)
qu --summary /
Show detailed statistics for two directory levels deep in my home directory (levels=2 is the default)
qu /
Show cumulative detailed statistics for three directory levels deep in my home directory
qu --levels=3 --cumulative /
qu -l 3 -c /
Show detailed statistics for ~/usr/local/lib
qu /usr/local/lib
Show detailed statistics for ~/usr/local/lib and sort the output based on which directories use the most blocks
qu --sort=blocks_reverse /usr/local/lib
Show detailed statistics for Bob's /usr/local/bin
qu --user=bob ~bob/usr/local/bin
