GNU
GNU is an extensive collection of free software which can be used as an operating system or can be used in parts with other operating systems. The GNU project founded by Richard Stallman has produced many free and open source tools that greatly impact the world as we know it today. My personal favorite of these tools is Emacs, but some of the other ones of note are:
- bash
- The default shell on many linux distros.
- clisp
- common lisp, the most popular variant of lisp.
- emacs
- What more could be said.
- fdisk
- Disk partitioning tool.
- gcc
- C compiler.
- grep
- A regex parser.
- grub
- The most popular open source boot loader.
- guile
- A variant of scheme (lisp programming language).
- less
- A file pager.
- make
- Software building and executing.
- nano
- A simple text editor.
- sed
- Text stream editor.
- Stow
- Config file manager.
- which
- Show execution path of a command.
