The program is a companion to the "du" file system utility. It is intended for the scenario where a system admininstrator discovers with "df" that there is no more or little extra space left on the file system. In a company with many departments the sysadmin cannot be expected to know what is causing the file system to fill up. The sysadmin may run the program to output a list of the n largest items in a given set of paths and thereafter take action on them.
The program first quicksorts its arguments to remove duplicates. Next it processes each argument in turn, descending into subdirectories. Directory sizes are computed recursively from the sizes of the entries in that directory. During this process the largest items are collected in a list. The program outputs the list at the end. There is a human-readable output format where the sizes are formatted as kilobytes, megabytes etc.

NAME
dumx - displays the largest files and/or directories in a
given list of paths
SYNOPSIS
dumx [OPTION]... [FILE]...
DESCRIPTION
This program will recursively process all files and direc-
tories given as arguments and output the largest items,
where directory sizes are computed by summing content
sizes.
OPTIONS
-n ENTRIES
Set the number of entries to retrieve, default is
10.
-h Produce human-readable output using suffixes K, M,
G etc. on file sizes.
-v Invert, i.e. find smallest items.
-type ARG
Files/directories only, the corresponding values of
ARG are 'f' and 'd'.
-xdev Don't descend into other file systems.
-uid NUMBER
Restrict to a given user id.
-gid NUMBER
Restrict to a given group id.
-user NAME
Restrict to a given user name.
-group NAME
Restrict to a given group name.
-regex PATTERN
Restrict to files matching extended POSIX regex
pattern.
