Free disk usage software for linux

xdiskusage is a user-friendly program to show you what is using up all your disk space.

It is based on the design of xdu written by Phillip C. Dykstra.

Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.

The arrow keys may be used to move the selected directory (shown with a red box) around. There is a pop-up menu (use the right mouse button) with other options for changing the display, you can hide nodes, make that node the "root", change the sort order, etc.

Disk Manager project is a simple filesystem configurator that allow you to:
- Automaticly detect new partitions at startup.
- Fully manage configuration of filesystem.
- Enable/disable write support for NTFS (need ntfs-3g installed).

Pod::Usage, pod2usage() can print a usage message from embedded pod documentation.

SYNOPSIS

use Pod::Usage

my $message_text = "This text precedes the usage message.";
my $exit_status = 2; ## The exit status to use
my $verbose_level = 0; ## The verbose level to use
my $filehandle = *STDERR; ## The filehandle to write to

pod2usage($message_text);

pod2usage($exit_status);

pod2usage( { -message => $message_text ,
-exitval => $exit_status ,
-verbose => $verbose_level,
-output => $filehandle } );

pod2usage( -msg => $message_text ,
-exitval => $exit_status ,
-verbose => $verbose_level,
-output => $filehandle );

pod2usage( -verbose => 2,
-noperldoc => 1 )

diskfree project is a shell script designed to be run periodically from cron to let you know how much disk space youve used, what directories have grown, which directories have shrunk, etc.
Installing
1. If you have Bash installed, then edit line 1 and point it to Bash. If you dont have Bash installed, but have the Korn shell installed, edit line 1 and point it to that (typically #!/bin/ksh).
2. Decide which directories you want reported on or if youre paranoid, remember to use the -p option. If you want something other than the default then use the -d option
3. Decide who should get the report. If it should go to root, dont do anything. If it goes to someone else, use the -m option (-m someone@somewhere.net)
4. Decide where you want the files this script creates to be put. If /tmp is OK with you, do nothing. If you want them elsewhere use the -l option (-l /var/log)
5. Decide how frequently you want the report run (daily, weekly, monthly, etc) If you want it run daily, then create on entry in your crontab like:
00 00 * * * /some/path/diskfree
If you want to run it monthly as well, I suggest you also add this to crontab:
00 02 01 * * /some/path/diskfree -e monthly
And quarterly would appear in crontab like:
00 04 01 */4 * /some/path/diskfree -e quarterly
6. Save your crontab.
7. Copy diskfree.8 /usr/man/man8
8. Wait for the script to run TWICE, then check your email and review the report
9. Send comments, bugs, suggestions to dhunley@columbus.rr.com
Enhancements:
- Altered the output to put the df output first and the details second.

PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file. The functionality offered is largely equivalent to the one offered by any filesystem, or by the Structured Storage and Compound Files.

PicoStorage can efficiently handle huge numbers of small files, with very economical disk usage; it also allows you to keep open (in RAM) simultaneously a large number of files. Transaction support guarantees data integrity.

Learn more about the distinctive advantages of PicoStorage. or look at the benchmark.

The library is available on a dual-license basis: under GPL for free, and under a commercial license for use in closed-source applications.

Using

The library contains the classes File and Dir to represent files and directories. On a File you can read or write a number of bytes from a given offset, and set/get the file size. On a Dir you can create entries (either files or subdirectories), open entries, delete entries, and iterate over the directorys content.

The storage itself (i.e. the whole hierarchical structure, contained in a filesystem file) is represented by the class Storage. Using this class, you can create or open a storage, obtain the root directory of the storage, close the storage and do commit or rollback.

Ice Sound Manager was designed to ease the management of sound events, sound themes, and the IceSound server in the IceWM environment under Linux/Unix. It is also intended to be an improvement upon the noble, but primitive icesndcfg.
The main improvements over icesndcfg include a support for sound event "themes", more comprehensive help, easy management and configuration of the IceSound server, a cleaner GUI interface, automatic starting of the IceSound server, and a more conservative approach to disk space usage. In addition, Ice Sound Manager includes a built-in "Setup" program which runs the first time you run Ice Sound Manager.
The application is written in Python (making it more easily ported across various platforms and architectures) and uses GTK through the PyGTK libraries. This application is available in both .tar.bz2, RPM, and static binary (for people without Python/PyGtk).
Please note that the tar.gz file does NOT need to be compiled (this is python, remember). System requirements are as follows: Python 2.2, PyGTK-2 1.9.9/2.0.0, IceWM (or IceWM-Gnome) 1.2.0 or better - with the IceSound Server executable (generally called, icesound or icesound-gnome). IceWM version 1.2.6 or better is highly recommended.
NONE of the following is required: Gnome, Gnome libs, or PyGnome (python-gnome). This application has NOT been tested with earlier versions of Python, IceWM, PyGTK, and IceSound Server. I cant say that it wont work with earlier versions, but I certainly cant say that it will. This application has NO dependencies on Gnome. 8-)

Ice Sound Manager has been designed and tested in the following environment(s): Mandrake 8.1, SuSe 8.1, Kernel 2.4.8 / 2.4.19, Glibc 2.2.4 / 2.2.5, XFree86 4.0.1 - 4.3.0, Python 2.2 - 2.2.1, PyGtk 0.6.9/PyGtk-2 2.0.0, Gtk version 1.2.8-4-1.2.10, Gtk+2 version 2.0.6, IceWM 1.0.9 - 1.2.15, IceWM-Gnome 1.0.9 / 1.2.2, with both icesound and icesound-gnome sound server executables. The test computers (3) were all Pentium 1, ranging in memory from 64MB to 256MB - nothing spectacular. It should run well on very old computers.
Requierments:
- Access to a Bash shell (very important), Python (2.2 or better), PyGtk-2 (1.9.9/2.0.0 or better), and Gtk+ 2.0.6 or better - neither Gnome nor PyGnome is required. (IceWMCP versions 2.5 and earlier require Gtk+1 and PyGtk-1 0.6.9) Repeat: IceWM requires NOTHING gnome-related.
- Also, your version of PyGtk should have the Gdk-Pixbuf modules on your system. Please run ALL IceWMCP programs from a BASH shell: Using other shells such as ksh, pdksh, csh, tcsh, etc. is likely to cause problems. If your IceWMCP programs have trouble launching other applications, it is most likely because you are using something other than a Bash (/bin/bash) shell. Run the programs from Bash...period! If you attempt to run the application and get ANY kind of error that says something like "Import Error", it means YOU do not have all the necessary Python libraries installed or do not have them installed correctly: This is NOT a bug, so do not file a bug report when you dont have the necessary software properly installed. Getting Python and PyGtk and getting them setup right is YOUR business. DO NOT ask for help installing Python, PyGtk, or GdkPixbuf. I recommend you get them from: http://speakeasy.rpmfind.net. If you are using a Python version lower than 2.2 and are too lazy to upgrade, use the "binary" distribution of IceWM Control Panel, or dont bother at all. NOTE: These requirements apply only to the standard pure-python version of IceWM Control Panel. Compiled, binary copies of IceWM Control Panel are stand-alone executables that do NOT require Python or PyGtk.
- Disk space requirements: The standard, pure-Python version of IceWM Control Panel uses approximately 1.75-2.2 MB of disk space - very small! The compiled, binary version of IceWM Control Panel uses about 3.7 MB of disk space. Yes, the binary version is large, so people too lazy or impatient to install Python and PyGtk properly and choose to use the stand-alone binary version will pay with disk space. At last check, the Hardware (or System) plug-in uses about 1.9 MB of disk space (most of it being the hardware ID data file).
