Free unix filesystems software for linux

Sys::Filesystem project is intended to be a portable interface to list and query filesystem names and their properties.

It hopes to provide a consistent API to list all, mounted, unmounted, and special filesystems on a system, and query as many properties as possible with common aliases wherever possible.

Non-Networked File System provides a consistent file system over several non networked UNIX computers (or slow networked). For example on your computer at home and at work using only a floppy disk for the synchronisation.
Main features:
- You are sure to work on the latest version of files.
- You dont need to remember which files are modified on an host and must be transfered on others.
- You dont need to made backup, because if a computer crash the file system is still on the other computers working with NNFS.
- The NNFS medium is choosen by a user shell script, it could be: floppy disk, usb key, serial connection, ...
- Minimal NNFS medium bandwidth to make the updates.
- EASY TO USE: Running ``nnfs command before and after your work.
- Numbered backup of files modified/deleted on NNFS.
- If you modify the same file on several hosts NNFS solves the update conflict.
- The program has been hugely tested.
Enhancements:
- This release fixes the case where the user modifies a file mode while NNFS is running and NNFS is configured in order that a file mode change does not imply file synchronization.

Filesys::Df is a Perl extension for filesystem disk space information.

SYNOPSIS

use Filesys::Df;

#### Get information by passing a scalar directory/filename value
my $ref = df("/tmp"); # Default output is 1K blocks
if(defined($ref)) {
print "Total 1k blocks: $ref->{blocks}n";
print "Total 1k blocks free: $ref->{bfree}n";
print "Total 1k blocks avail to me: $ref->{bavail}n";
print "Total 1k blocks used: $ref->{used}n";
print "Percent full: $ref->{per}n";

if(exists($ref->{files})) {
print "Total inodes: $ref->{files}n";
print "Total inodes free: $ref->{ffree}n";
print "Inode percent full: $ref->{fper}n";
}
}

#### Get information by passing a filehandle
open(FILE, "some_file"); # Get information for filesystem at "some_file"
my $ref = df(*FILE);
#### or
my $ref = df(*FILE);
#### or
my $fhref = *FILE;
my $ref = df($fhref);

#### Get information in other than 1k blocks
my $ref = df("/tmp", 8192); # output is 8K blocks
my $ref = df("/tmp", 1); # output is bytes

This module provides a way to obtain filesystem disk space information. This is a Unix only distribution. If you want to gather this information for Unix and Windows, use Filesys::DfPortable. The only major benefit of using Filesys::Df over Filesys::DfPortable, is that Filesys::Df supports the use of open filehandles as arguments.

The module should work with all flavors of Unix that implement the statvfs() and fstatvfs() calls, or the statfs() and fstatfs() calls. This would include Linux, *BSD, HP-UX, AIX, Solaris, Mac OS X, Irix, Cygwin, etc ...

df() requires a argument that represents the filesystem you want to query. The argument can be either a scalar directory/file name or a open filehandle. There is also an optional block size argument so you can tailor the size of the values returned. The default block size is 1024. This will cause the function to return the values in 1k blocks. If you want bytes, set the block size to 1.

df() returns a reference to a hash. The keys available in the hash are as follows:
{blocks} = Total blocks on the filesystem.
{bfree} = Total blocks free on the filesystem.
{bavail} = Total blocks available to the user executing the Perl application. This can be different than {bfree} if you have per-user quotas on the filesystem, or if the super user has a reserved amount. {bavail} can also be a negative value because of this. For instance if there is more space being used then you have available to you.
{used} = Total blocks used on the filesystem.
{per} = Percent of disk space used. This is based on the disk space available to the user executing the application. In other words, if the filesystem has 10% of its space reserved for the superuser, then the percent used can go up to 110%.
You can obtain inode information through the module as well, but you must call exists() on the {files} key first, to make sure the information is available. Some filesystems may not return inode information, for example some NFS filesystems.
Here are the available inode keys:
{files} = Total inodes on the filesystem.
{ffree} = Total inodes free on the filesystem.
{favail} = Total inodes available to the user executing the application. See the rules for the {bavail} key.
{fused} = Total inodes used on the filesystem.
{fper} = Percent of inodes used on the filesystem. See rules for the {per} key.

There are some undocumented keys that are defined to maintain backwards compatibilty: {su_blocks}, {user_blocks}, etc ...

If the df() call fails for any reason, it will return undef. This will probably happen if you do anything crazy like try to get information for /proc, or if you pass an invalid filesystem name, or if there is an internal error. df() will croak() if you pass it a undefined value.

Unix Amiga Delitracker Emulator (UADE) plays most Amiga music file formats by simulating Amiga hardware and software.
Unix Amiga Delitracker Emulator plays over 180 Amiga music file formats and has three frontends for playing: a command line tool, an XMMS plugin, and a Beep Media Player frontend.
Enhancements:
- An improved version of the Special FX replayer was added.
- A new Special FX ST replayer was added.
- Bugs in song length database handling were fixed.
- Audacious 1.3 is supported.
- 15 instrument soundtracker module detection is supported.

The goal of RUMT is to check the memory of a computer over a long period of time and almost-real load conditions without having to interrupt the services.

RUMT exploits the possibility of some Unix kernels to selectivly disable some memory areas while still accessing them through the /dev/mem device. The principle of RUMT is to write pseudo-random data in these disabled memory areas, and later check them. This principle and the original code for the deterministic pseudo-random generator are from David Madore.

This distribution contains another variant on the same theme: URUMT allocates a large chunk of memory, locks it in memory using the mlock(2) system call, and scans /dev/mem to find where in physical memory the allocated area is. Then it continuously runs the same tests in that memory.

URUMT can not be used to test a particular area of memory: the kernel will give it whatever physical memory it feels like. But URUMT can be restarted now and then, hopefully getting different physical memory each time.

This is perfect if you suspect you have bad bits, but do not know at all where they are. Once you have sighted the bad bits, you can use a plain RUMT to test more extensively the neighborhood.

This is a collection of scripts which is used to manage the creation of Slackware packages. This framework is designed to make it easy to add packages to the collection and to easily tweak package parameters for testing and deployment.
The framework currently has a lot of parameters, and also has basic frameworks for CPAN packages. It is possible to add more frameworks and tweaks for other package networks as well, such as the PHP and Python archives, and these are in the works currently.
Enhancements:
- This marks the start of the new style of build scripts. These are much more modular, and have a consistent set of shell functions and variables which work in their defaults for most situations, and can be redefined by a package file to do special setup or other functions
- which some packages may require.
