A gdb-like debugger for bash

Minimal Linux Live is a tiny educational Linux distribution, which is designed to be built from scratch by using a collection of automated shell scripts. Minimal Linux Live offers a core environment with just the Linux kernel, GNU C library and Busybox userland utilities. Additional software can be included in the ISO image at build time by using a well-documented configuration file. Minimal Linux Live can be downloaded as a pre-built image, built from scratch or run in a web browser by using a JavaScript PC emulator.

Avoid switching between Clojure and bash scripts. Enjoy your parens on the command line. Leveraging GraalVM native-image and the Small Clojure Interpreter, babashka is a self-contained and instantly starting scripting environment. Babashka comes with scripting batteries included: tools.cli, cheshire, babashka.fs, babashka.process, java.time and many more libraries and classes. Babashka scripts work on linux, macOS and Windows. Besides the built-in libraries, babashka is able to load libraries from source, tapping into the world of already existing Clojure libraries. Babashka supports real JVM threads and like Clojure, supports futures and dynamic thread-locally bound vars. Babashka features a built-in task runner which covers the most popular use cases of make, just and npm scripts. Babashka can shell out to other CLI programs like you are used to in bash. It goes one step further and offers seamless integration with other binaries using the pod protocol.

Finally, a command line shell for the 90s. fish is a smart and user-friendly command line shell for Linux, macOS, and the rest of the family. fish suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0! fish supports 24 bit true color, the state of the art in terminal technology. Behold the monospaced rainbow. fish is fully scriptable, and its syntax is simple, clean, and consistent. You'll never write esac again. For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page. Other shells support programmable completions, but only fish generates them automatically by parsing your installed man pages. fish will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.

Do you want a more robust experience from your bash shell? As a Linux systems administrator, I've been working on this .bashrc file for well over a decade. Over the years, I have searched through scores of others' .bashrc and script files collecting and improving on new ideas and features. This portable drop in bash configuration file can be used on any system anywhere you use a terminal. It will detect most settings on most systems and make sure your environment has every feature available automatically without any additional effort. Do you need a command line cheat sheet? Press CTRL-h for full color help! I think this is the most amazing, ultimate .bashrc file I have ever seen and wanted to share it. To install, execute the following lines in a terminal wget -O ~/.bashrc https://sourceforge.net/projects/ultimate-bashrc/files/_bashrc/download wget -O ~/.bashrc_help https://sourceforge.net/projects/ultimate-bashrc/files/_bashrc_help/download

SoupToNuts is a repository of technical articles and example software covering Postfix, OpenSSH, C and C++, Live Linux CD, MySQL, SQLite, Berkeley DB, Bash and System Administration.

env-switcher effectively allows users to manipulate the environment loaded for all shells (including non-interactive remote shells) without manually editing their startup dot files -- something that users traditionally have difficultly doing properly.

Mainly this project aims at easing startup and use of XCSoar (see xcsoar.org) on Kobo Mini. But the scope of use should not be limited solely to XCSoar. The Launcher should be small in code size, reuse most of the original libraries, provide flexible configuration to any application that might be ported to the Kobo Mini. It supports customizable fonts, toolbox-pages, buttons (also graphical), labels, autostart and sleep timers.

A set of functions for KSH and BASH in a sourceable file. Typical functions include calculating differences between dates, going forward or back any number of days. Works for dates AD only. Some issues will arise when today > 2099...

A SuperSimple x86_64 Micro Linux ASCII Desktop Distro An excellent system-development distribution. Comes with kernel, libc, cc, emacs, theTool, and an rc. Designed to bootstrap g++. Roll-your-own distro, bring tarballs. Notes for the current dist: 1. Edit '/etc/fstab' 2. Add link from /psu to /proc 3. Use theTool to build Perl. 4. Build (binutils) gcc-4.7.2 with c++. 4. Build gcc-8.3.0 with c++. 4. Build gcc-15.2.0 with c++. 7. Try to build linux7 (could it get Any better?) 4. Remove '--disable-nls' option from cfg before configuring gettext. See the shell programs and filesystem in the 'Files' section. Also see the /.bash_history file. Be sure to post in the forum/discussion 'kconfig' because there are a few caveats to "boot and build". V0 -- kernel4.2(generic), gcc 4.7.2, has ip4+nls. V1 -- k4.2(core2) with amdgpu+ACPI V2 -- k7.0, gcc 15.2.0 -- SLOW!? v0 builds kernel in 45 seconds! Thanks, Dru

Mussh is a shell script that allows you to execute a command or script over ssh on multiple hosts with one command. When possible mussh will use ssh-agent and RSA/DSA keys to minimize the need to enter your password more than once.

Easily configure bash completion scripts on a per-user or system-wide basis.

A modular framework for implementing a CISCO-like CLI on a *NIX system. Arbitary command menus and actions can be defined using XML files. This software handles the user interaction, and forks the appropriate system commands to perform any actions.

A tool to auto-compile & install Nginx+MySQL+PHP on Linux

This is a simple script to compress a file, a folder, multiple files, multiple folders with password protect.

cdq is a tool to change directory quicky.After adding frequently accessed directories to cdq database,you can change to one directory by inputting its index,if it is in the database.This tool is valuable if you need change among directories frequently.

ScriptEchoColor simplifies Linux terminal text colorizing, formatting and several steps of script coding.

Debsysinfo is a system information gathering script for GNU/Linux Debian . It is non-intrusive and simply gathers information from commands that are already available.

pipestatus - source file for UNIX/POSIX shell that allows to obtain an exit status of every program in a pipe.

Do you want the power of a fully loaded tmux plugin framework without installing a single plugin? One file. No plugin managers. No dependencies. No setup. Drop it on any machine and it just works. What you get feels like a desktop app: a menu system with submenus, a 21-app launcher, searchable help, a built-in scratchpad, a system dashboard, and a fully clickable status bar. All in a beautiful adaptive interface that auto-detects your fonts and scales from Nerd Font icons to plain ASCII on a TTY. The status bar knows when you are in SSH and moves out of the way. The clipboard works everywhere including over SSH. Every feature degrades gracefully. Nothing breaks if a tool is missing. To install: wget -O ~/.tmux.conf https://sourceforge.net/projects/ultimate-tmux/files/_tmux.conf/download Also includes: system tray icon (tmux-tray), terminal launchers for 5 terminals, and a WezTerm config. Companion: Extreme Ultimate .bashrc (sourceforge.net/projects/ultimate-bashrc)
