# SYNOPSIS
|
|
# du [--disk|--dir|--dua] [args...]
|
|
#
|
|
# DESCRIPTION
|
|
# Smart disk-usage dispatcher. Without flags, routes to the most appropriate
|
|
# tool by context; explicit flags force one. Falls back to system du when the
|
|
# preferred tool is not installed.
|
|
#
|
|
# ARGUMENTS
|
|
# --disk Force duf (disk-level free/used overview)
|
|
# --dir Force dust (per-directory tree breakdown)
|
|
# --dua Force dua (fast interactive space analyzer)
|
|
# args... Files/directories or flags forwarded to the selected tool
|
|
#
|
|
# EXAMPLE
|
|
# du ~/Downloads
|
|
# du --disk
|
|
function du --description 'Execute du'
|
|
# Opinionated guard (C1): fall back to bare command du when disabled.
