rsynchelper helps you use the mirroring program rsync. rsynchelper makes it easier for groups of servers to cooperate in mirroring. rsynchelper makes it easier to make your content available for others to mirror, makes it easier to mirror someone else's content, and it automates the maintenance of an accurate list of who is maintaining which content.
g4u ("ghost for unix") is a boot-floppy/CD that allows one to easily clone PC hard disks by using FTP. This is often done to deploy a common setup on a number of PCs. The floppy/CD offers two functions: it uploads the compressed image of a local hard disk to an FTP server, and then it can retrieve that image via FTP, uncompress it, and write it back to disk. Network configuration is fetched via DHCP. As the hard disk is processed as an image, any filesystem and operating system can be deployed using g4u. Easy cloning of local disks as well as partitions is also supported.
Installwatch is a simple utility which keeps track of which files are created and modified during the installation of a new program. It's fast and easy to use. It doesn't require a "pre-install" phase because it monitors processes while they run. Installwatch works with every dynamically linked ELF program, by intercepting system calls that cause file system alterations.
atool is a script for managing file archives of various types (tar, tar+gzip, zip etc). The main command is aunpack, which extracts files from an archive. It overcomes the problem of extracting files from an archive without checking whether the files were located in a subdirectory or in the top directory of the archive, resulting in files scattered all over the place by first extracting to a new directory. If there was only a single file in the archive, that file is moved to the original directory. It also prevents local files from being overwritten by mistake. The other commands are apack for creating archives, als for listing files in archives, and acat for extracting files to standard out.
The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. Its major features include fast random access to compressed data, freedom from patents, single-pass coding/decoding using a bounded amount of intermediate storage, the ability to choose from one of many algorithms for compression, encryption, or error correction, and comprehensive support for Unix file metadata, Macintosh file metadata, and arbitrary file metadata.
httplog is a replacement for Apache's 'rotatelogs' and Andrew Ford's 'chronolog'. It allows you to specify a logfile using strftime paramaters in the filename to act as a template. This means that the logs in your logfiles will also be sorted according to the filename. For example, if you specify a logfile of /var/log/http%Y%m%d.log, a new log file would be generated each day, with content for only that one day. It also supports compression of logfiles using gzip, and many other useful functions.
