execline is a very light, non-interactive scripting language, which is similar to a shell. Simple shell scripts can be easily rewritten in the execline language, improving performance and memory usage. execline was designed for use in embedded systems, but works on most Unix flavors.
fish, the friendly interactive shell is a shell that is focused on interactive use, discoverability, and user friendliness. The design goal of fish is to give the user a rich set of powerful features in a way that is easy to discover, remember, and use. fish features a user-friendly and powerful tab-completion, including descriptions of every completion, tab-completion of strings with wildcards, and many completions for specific commands. It also features an extensive and discoverable help system. A special help command gives access to all the fish documentation in your preferred Web browser. Other features include syntax highlighting with extensive error checking, support for the X clipboard, smart terminal handling based on terminfo, an easy to search, no duplicates history.
Groovy is an agile, dynamic language for the JVM which combines many features from languages like Python, Ruby, and Smalltalk and makes them available to Java developers using a Java-like syntax. It is designed to help get things done on the Java platform in a quicker, more concise, and fun way. It can be used as an alternative compiler to javac to generate standard Java bytecode to be used by any Java project or it can be used dynamically as an alternative language, such as for scripting Java objects, templating, or writing unit test cases.
The Heirloom Bourne Shell is a portable variant of the traditional Unix shell. It is especially suitable for testing the portability of shell scripts and for processing legacy scripts. The Bourne shell does not provide as many features as newer Unix shells, but it does provide a stable shell language. With this in mind, it is also suitable for general script processing and interactive use. This variant of the Bourne shell has been derived from OpenSolaris code and thus provides the SVR4/SVID3 level of the shell.
BUSH (Business Shell) combines the capabilities of BASH, PHP, GCC, and databases into a uniform design for rapidly building secure, reliable Web sites. Based on an ISO standard, it promotes code reuse: scripts and templates can be compiled with GCC or ported to JVM or .Net using third party tools with only minor changes. It can also replace BASH as an interactive command shell with SQL support, and is a general purpose scripting language.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. It is the simplest solution to numerical computing and visualization in the domain of C/C++. It supports the ISO 1990 C Standard (C90), major features in C99 (complex numbers, variable length arrays or VLAs, type generic functions, long long data type, etc), classes in C++, and extensions to the C language like nested functions, string types, etc. It can be embedded in other applications and hardware and used as a scripting language. C/C++ code is interpreted directly with no compilation to intermediate code. It supports Linux, Windows, MacOS X, Solaris, HP-UX, and FreeBSD.
