OMake is a build system and scripting language with a similar style and syntax to GNU make but with many additional features, including support for large projects spanning multiple directories, default configuration files simplifying the standard compilation tasks, fast, reliable, automated, scriptable dependency analysis using MD5 digests, built-in support for defining and running autoconfiguration tests, portability, and built-in functions that provide the most common features of programs like grep, sed, and awk. It also provides active filesystem monitoring that restarts builds automatically when source files are modified. A companion command interpreter that can be used interactively is included.
The Tecla library provides programs with interactive command line editing facilities, similar to those of the Unix tcsh shell. It supports recall and editing of previously entered command lines, TAB completion of file names and application specific tokens, and in-line wild-card expansion of filenames. The optionally reentrant modules which perform TAB completion and wild-card expansion are also available separately for general use. The library is smaller, more modular, makes more efficient use of the heap, and has a less restrictive license than GNU readline.
rrs is a reverse (connecting) remote shell. Instead of listening, it will connect out to rrs in listen mode. The listener will accept the connection and receive a shell from the remote host. rrs features full pseudo-TTY support, full OpenSSL support (client/server authentication and choice of cipher suites), Twofish encryption, a simple XOR cipher, plain-text sessions, peer-side session snooping, a daemon option, and reconnection features. It is known to compile and run under Linux, FreeBSD, NetBSD, OpenBSD, and QNX.
Pexpect is a Python Expect-like module. It spawns child applications, controls them, and responds to expected patterns in their output. It can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. It can be used to automate setup scripts for duplicating software package installations on different servers. It can be used for automated software testing. It should work on any platform that supports the standard Python pty module. Its interface was designed to be easy-to-use, so performing simple tasks is easy. It includes an ANSI/VT100 terminal screen scraping module.
ded, the directory editor, allows you to navigate multiple file lists or a directory tree, viewing or changing file attributes rapidly. In addition to conventional file information, it operates on files' RCS or SCCS archives, making it useful for source control as well as system administration. It is curses-based.
epto is a small library and framework for industrial strength shell script programming with sh. It features convenient error handling, tracing, logging, option handling, documentation template, process level transaction safety (sort of), and more. If one is used to shell programming, it takes less than five minutes of learning to start using it (see the crash course in the README file).
Shuriken is an XML-based tool for Linux system administrators to set up spans of time when the system should be up. Using the RTC daily alarm (requires BIOS, hardware, Linux support), the system will automatically power-on (if it is off) for these intervals. Automatic power-off is supported, but this feature is not recommended if users intend to log in to the system and not have it shut down on them.
