XDU(1)XDU(1)NAMExdu - 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 utiliza‐
tion as reported by the UNIX utility "du". The user can navigate
through the tree structure and change the order of the displayed infor‐
mation. 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 occu‐
pied 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 hap‐
pens 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:
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 sec‐
tion.
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-*
XDu.showsize: False
XDu.order: size
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
