ised is a command-line tool for generating number sequences and arithmetic evaluation. Unlike big gui-based software (e.g. Mathematica, Derive, Matlab, Octave,...) it is intended for use in shell scripting, together with gnu core utilities. Its main advantage is that all functions are generalized to operate on one-dimensional arrays. It can be used for loop indexing (much like seq), line-by-line arithmetic processing of files, floating point math for shells that don't support it natively, or interactively, as extended calculator.

Twisted Conch is an SSHv2 implementation written in Python. SSH is a protocol designed to allow remote access to shells and commands, but it is generic enough to allow everything from TCP forwarding to generic filesystem access. Since conch is written in Python, it interfaces well with other Python projects, such as Imagination. Conch also includes a implementations of the telnet and vt102 protocols, as well as support for rudamentary line editing behaviors. A new implementation of Twisted's Manhole application is also included, featuring server-side input history and interactive syntax coloring.

This is a small shell script intended to be used in portable Unix install scripts for showing progress bars. The overall goal is to write a minimally complex shell script (thus a program that needs no compilation) that is as robust as possible to work on as many Bourne shells and operating systems as possible, and that implements 'cat' with an ASCII progress bar and some other nifty features. This is pure Bourne shell code. (For sh, ash, ksh, zsh, bash, ...) The script is mainly indented to be used in portable install scripts, where you can use the body of the script.

gqlplus is a drop-in replacement for sqlplus, an Oracle SQL client, for UNIX platforms. The difference between gqlplus and sqlplus is command-line editing and history, plus tablename completion. As you know if you have used sqlplus, it is notoriously difficult to correct typing errors and other mistakes in your SQL statements. sqlplus does give you ability to use external editor to edit a statement, but only the last statement you typed. gqlplus solves this problem by providing the familiar command-line editing and history as in tcsh or bash shells, and tablename completion, while otherwise retaining compatibility with sqlplus. Thus, no user training is needed - simply use gqlplus instead of sqlplus. In addition, configuration/installation is trivial: gqlplus is a single binary compiled executable (written in C), so all you need is download it and put it anywhere in your PATH. After that, you'll be ready to use it.

JLine is a Java library for handling console input. It is similar in functionality to BSD editline and GNU readline. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar. JLine is distributed under the BSD license, meaning that you are completely free to redistribute, modify, or sell it with almost no restrictions. API documentation can be found in the apidocs directory. You can use the jline.ConsoleRunner application to set up the system input stream and continue on the launch another program. For example, to use JLine as the input handler for the popular BeanShell console application, you can run: java jline.ConsoleRunner bsh.Interpreter

This module is a wrapper around Getopt::Long that extends the value of the original Getopt::Long module to: 1) add a simple graphical user interface option screen if no arguments are passed to the program. 2) provide an auto-help mechanism such that -h and --help are handled automatically. It's designed to make the creation of graphical shells trivial without the programmer having to think about it much as well as providing automatic good-looking usage output without the programmer needing to write usage() functions. This also can turn normal command line programs into web CGI scripts as well (automatically). If the Getopt::GUI::Long program is installed as a CGI script then it will automatically prompt the user for the same variables.

pipestatus - source file for POSIX shell that allows to obtain an exit status of every program in a pipe. MOTIVATION When we program in shell we often run pipes like this prog1 args1 | prog2 args2 | ... | progN argsN POSIX says that exit status of pipe is the exit status of LAST program in it, i.e. progN in our example. That is, exit status of all other programs in pipe is silently ignored. But in many situations exit status of all programs in pipe should be checked to make program robust. Some shells like BASH and ZSH have special extensions for doing this but POSIX shell unfortunately doesn't provide an EASY way for doing this. In order to solve the problem, described above pipestatus was written.

Munger is a simplified, statically-scoped, interpreted lisp specialized for writing text processors for 8-bit text. With Munger the programmer may write line-by-line filters, if serial access to the text is sufficient, or the programmer may load text into buffers and have line-oriented random access to those lines, if that is more convenient. Munger makes it easy to write simple text editors, shells, utility filters, CGI scripts, and simple network client and server programs. Mung (or munge) is computer jargon for, "to make repeated changes which individually may be reversible, yet which ultimately result in an unintentional irreversible destruction of large portions of the original item." Laugh, it's a joke.
