changedfiles is a framework for filesystem replication, security monitoring, and/or automatic file transformations--essentially any application where you'd poll files or directories and either do something to them or send them somewhere else (or both). The difference is that the kernel tells you when they change instead of you having to poll. It's an easy real time FTP push mirror to one or multiple sites. It's also a full fledged MySQL client, so you can do realtime database operations (for example, batch imports). It consists of two parts: a kernel module (works with Linux kernel version 2.4) which reports to a device whenever a file on the filesystem changes, and a daemon which runs in user space and can be configured to do almost any action when a change to a file matching the one of the patterns it looks for is reported. The kernel module is SMP safe and has been tested on Intel, PowerPC, and Alpha.
BitchBurn is a bash script written to make life as a CD burner a bit easier. It covers the most common options in a very simple way. The extended features of the handy tool are: cleaning CDRWs, copying data/audio discs, burning directories to disc, burning iso's to disc, and burning mp3 directories to audio discs.
The poldek is an RPM package management tool which allows you to easily perform package verification, installation (including system installation from scratch), upgrading, and removal. Package dependencies are automatically handled, so if you try to install a package that needs others to be installed, it will download all needed packages and install them. It can be used in batch (like apt-get from Debian's APT) or interactive mode. The interactive mode puts you into a readline interface with commandline autocompletion and history, similar to the shell mode of Perl's CPAN.
DeepManager aims to be a package dependency manager, helping you to better understand the relations between a set of packages. It has two main operations modes: "dot" builds a graph showing selected relations to be viewed with graphviz, and "check" verifyies consistency in the given information sources. It supports reading from RPM hdlists or an RPM database.
fsbackup is an incremental backup creation utility. It supports backup compression and encryption. Backups can be stored on the local file system, and a remote host (via SSH, or FTP). Some additional scripts allow backup SQL tables from PostgreSQL and MySQL, save system configuration files, and a list of installed packages. Backed-up files can be recovered, and system packages can be reinstalled.
