NAME

       xdiskusage - Graphical display of disk usage

SYNOPSIS

       xdiskusage   [-a]  [-d[isplay]  host:n.n]  [-g[eometry]  WxH+X+Y]  [-t[itle]  windowtitle]
       [-n[ame] classname] [-i[conic]]  [-fg  color]  [-bg  color]  [-bg2  color]  [directory...]
       [file...]

DESCRIPTION

       xdiskusage  displays  the  output of "du" in an X window, allowing you to compare visually
       the space occupied by files and directories.

USAGE

       Typing "xdiskusage dir" where "dir" is a folder causes "du" to be run on that  folder  and
       the  result  displayed.   If  the  named file is a symbolic link it is dereferenced before
       being sent to du. The "-a" switch, if given, is passed to "du" to cause all  files  to  be
       measured.

       Typing  "xdiskusage file" where "file" is not a folder makes xdiskusage parse that file as
       though it was "du" output and display the result.

       You can type several file and folder names and get several display windows.

       If no files are named, you can pipe the output from  another  program  to  xdiskusage.  If
       stdin  is  not  a terminal xdiskusage will parse it as "du" output and display the result.
       For instance "du -k . | xdiskusage".

       Typing just "xdiskusage" brings up the disk browser described here:

DISK BROWSER

       By default xdiskusage presents you with a list of all the disks mounted on your system (it
       found  these  by running "df").  Click one of these names and it will scan the entire disk
       (by running "du") and present a graphical display of how much  space  all  the  files  are
       taking on that disk.

       You  can  click  on several disks (or on the same disk multiple times, for instance if you
       have changed the files stored on it) and get multiple display windows.

       The "rescan" button reruns "df" to get a new list of disks.  You need to do  this  if  you
       mount or unmount a disk, or to see new usage percentages.

       The (C) button shows you the copyright and license.

       You  can type a filename into the input field on the bottom and type Enter. If the name is
       a directory, xdiskusage will attempt to run "du" on it and display the result. If the name
       is a file it is assumed to be "du" output and it is parsed and displayed.

       The  "all files" button sends the -a switch to "du" causing it to list the space for every
       file on the disk.  This can significantly increase the time it takes to scan.

DISPLAY

       Each white box represents a folder.  It's size is equal to the sum of  all  it's  contents
       (all  sub-folders and files).  To the right of each box are stacked the boxes for the sub-
       folders (and files if the "all files" switch was given).

       If you selected a disk from  the  disk  browser,  some  extra  boxes  are  added  to  show
       information learned from df:

         "(free)" is the free space reported by df.

         "(permission denied)" is space that df said was used but du did not
         report. Besides permission errors when running du, this may also be
         the result of a file deleted from its containing folder, but still
         in use by a program, so its space is not reclaimed yet. Mounted
         loopback filesystems (ISO image just checked before burning, then
         deleted while still mounted) are common examples.

         "(inodes)" is the difference between the total size of the disk and
         the used + available space reported by du, this is overhead used by
         the file system.

       The  left-most box is the "current root". One of the boxes is outlined in red, this is the
       "current node".

       Clicking on any box makes it the current node. The arrow keys can also be used to navigate
       you  around.  Hitting return makes the current node be the current root: putting it on the
       left edge and blowing it up to the height of the window and scaling all it's contents  the
       same.  The  left  arrow  can be used to move the root and current node back up, or you can
       type '/' to move just the root, leaving the current node where it is.

       To dismiss any window type Escape.

MENU ITEMS

       There is a pop-up menu on the right-hand mouse button.  Every  item  on  the  menu  has  a
       keyboard shortcut.  The menu items are:

       In (right arrow) go to the first child of the current folder.

       Next (down arrow) go down to brother of current folder.

       Previous (up arrow) go up to the brother of current folder.

       Out (left arrow) go to parent of current folder.

       Root out (slash) move the root of the window up to it's parent.

       Hide (h) remove this node from the display and scale rest up to fit

       Unhide (H) Recursively turn off the hide flag from all children

       Sort/Largest (s) sort largest size at the top

       Sort/Smallest (r) sort smallest size at the top

       Sort/Alphabetical (a) sort in alphabetical order

       Sort/Reverse Alphabetical (z) sort in backwards alphabetical order

       Sort/Unsorted (u) sort in the order read from du.

       Columns/2-11 (2-9,0,1) arrange display to have N columns.

       Copy  to Clipboard (c) the pathname of the current node is put in the X clipboard (you can
       then paste it into a shell command).

       Print (p) The current display is printed.  The output is Encapsulated PostScript.  It will
       either run it through lpr (or any command you choose) or send it to a file.

BUGS

       Gets confused by "df" output on some platforms, requiring platform-specific code.
