Chef is a systems integration framework, built to bring the benefits of configuration management to your entire infrastructure. With Chef, you can manage your servers by writing code, not by running commands (via Cookbooks), integrate tightly with your applications, databases, LDAP directories, and more (via Libraries), and easily configure applications that require knowledge about your entire infrastructure ("What systems are running my application?" "What is the current master database server?").
Mr Bix is a TCP proxy of sorts in which an incoming connection becomes two outgoing connections, only one of which returns data to the original incoming connection as with a normal TCP proxy; data returned from the other is discarded. It is intended to be used to permit testing of new services or servers with live traffic.
tsf is a command line utility for creating timestamped copies of files. When invoked on a file, a copy of that file is created with a name made of the file name plus a timestamp. When invoked again on the same timestamp mark, a copy with a timestamp plus a sub-index is created, and so on. tsf provides an easy and quick way for creating timestamped copies of files before modifying them.
RHash is a utility for computing hash sums and creating magnet links. It supports CRC32, MD4, MD5, SHA1/SHA2, Tiger, TTH, Torrent BTIH, AICH, ED2K, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R 256/512, WHIRLPOOL, and SNEFRU hash algorithms. Hash sums are used to ensure and verify the integrity of large volumes of data for long-term storage or transferral. RHash can calculate magnet links and EDonkey 2000 links. It can update existing hash files by adding sums of files missing in the hash file. It can output in a predefined (SFV, BSD-like) or user defined format. It can process directories recursively.
sysfunc is a shell library intended for Unix sysadmins. It provides a set of portable shell functions including features such as file copy, symbolic link management, file/dir deletion, user/group management, data block replacement in a file, line replacement, commenting/uncommenting lines, service management, and volume group/logical volume/file system creation.
