NAME
xdu - display the output of "du" in an X window
SYNOPSIS
du | xdu [options]
DESCRIPTION
Xdu is a program for displaying a graphical tree of disk space
utilization as reported by the UNIX utility "du". The user can
navigate through the tree structure and change the order of the
displayed information. The window is divided up into several columns,
each of which is one level deeper in the directory hierarchy (from
left to right). Boxes are drawn for each directory. The amount of
vertical space occupied by each box is directly proportional to the
amount of disk space consumed by it and all of its children. The name
of each directory and the amount of data are displayed provided that
there is enough space within its box. Any space at the "bottom" of a
box not covered by its children to the right represents the space
consumed by files in that directory (as opposed to space from its
children).
There are several command line options available. Equivalent
resources (if any) are shown with each option.
+s (.showsize: true) display sizes (the default).
-s (.showsize: false) don't display sizes.
-c num
display num columns.
-a (.order: alpha) sorts display alphabetically.
-ra (.order: ralpha) sorts display reverse alphabetically.
-n (.order: size) sorts display numerically (largest first).
-rn (.order: rsize) sorts display reverse numerically (smallest
first).
-fg color
(.foregound) determines the color of the text and lines.
-bg color
(.background) determines the color of the background.
-rv reverse video (for monochrome displays)
In addition to these the usual toolkit options such as -rv, -font,
-display, -geometry, are supported.

MOUSE ACTIONS
The user can move up or down the tree by clicking the left mouse on a
directory box. If the left most box is selected, the display will
move up one level (assuming you are not already at the root). If any
other box is selected, it will be placed against the left edge of the
window and the display will be rescaled appropriately. At any time
the middle mouse will bring you back to the root. Clicking the right
mouse will exit the program.
KEYSTROKES
Several keystroke commands are supported. Note that all sorting
happens from the current root node down, so it is possible to sort one
subtree differently than another by clicking into it, doing a sort,
and going back up to the parent.
1-9,0
sets the number of columns in the display (0 = 10).
a alphabetical sort.
n numerical sort (largest first).
f first-in-first-out sort (this is the order the data was read into
the program).
l last-in-first-out sort.
r reverse sense of sort.
s toggle size display.
h display a popup help window.
i display information about the current root node to standard out.
The first line shows the path within the tree, the total size
from this node on down, and the precentage that total represents
of all of the data given to xdu. Subsequent lines show the size
and name information for all children of this node in the order
they are currently sorted in. This allows tiny directories to be
seen that otherwise could not be labled on the display, and also
allows for cutting and pasting of the information.
/ goto the root.
q (or Escape) exit the program.
ACTIONS
All mouse and keyboard events trigger actions so they can all be
rebound by translations to suit the individual. The action functions
are:

X11
reset()
goes to the root node.
goto()
moves down into the directory currently under the mouse (and is
thus probably only useful bound to a mouse button).
quit()
exits the program.
reorder(type)
sorts the display from the current root node down according to
one of: alpha, ralpha (reverse alphabetical), size (largest to
smallest), rsize (smallest to largest), first (as originally read
in), last (opposite of original data), reverse (reverse whatever
sort mode is currently selected).
size()
toggles size display on/off
ncol(num)
sets the number of columns to num.
info()
displays directory information as described in the KEYBOARD
section.
help()
displays a popup help window.
As an example of rebinding these, you could put the following in your
resources file:
XDu*translations: #override\n\
<Key>X: reorder(reverse)\n\
<Btn3Down>: info()
to make the 'x' key reverse the current sort order and the right mouse
button print the directory information message.
RESOURCES
The following resources are supported with some sample values.
XDu*foreground: yellow
XDu*background: blue4
XDu*window.width: 600
XDu*window.height: 480
XDu*help*foreground: green
XDu*help*background: red4
XDu.ncol: 5
XDu.font: -*-helvetica-bold-r-normal--14-*

EXAMPLE
cd /usr/src
du > /tmp/du.out
xdu -n /tmp/du.out
BUGS
On some machines keyboard input may not be accepted by xdu until the
mouse is moved out of and back into the window. I have been told that
putting the following in your resources file may fix this.
<window manager name>.FocusLenience: True
