+#+title: arsh - ARchaic SHell
+
+Since I started using GNU/Linux, I always wondered, how do shells work and what exactly are they responsible for. 
+
+In order to learn it (and also to use some C) I decided to implement a simple shell in C in a /single file/, where I would try to implement some of the features, that other shells like bash, zsh, fish, etc have. And also I wanted to use no external dependencies, except for the standard C library.
+
+* Features
+Some of the implemented features are:
+- You can pipe stdout of one command to stdin of another (ex. ~cat main.c | wc --lines~)
+- You can redirrect output/input with ~>~, ~>>~, ~<~, ~2>~, ~&>~
+- Variables expansion with ~$PATH~ and ~${HOME}~ syntax
+- Shows custom prompt, if ~PS1~ env variable is set
+- Run subcomands with ~$(hostname)~ or ~`pwd`~ (works with pipes)
+- Custom ~readline~ function with support for cursor moving (<-, ->) and inline editing
+- Run the shell in interactive and non interactive mode
