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
(.foreground) 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 percentage 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 labeled 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 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-*
 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
