# 21sh

Mini UNIX command interpreter.

![Demo](images/21sh.gif)

21sh uses my own implementation of libc's functions, most of them start with `ft_`

21sh implements:

* A series of builtins

 * echo

 * cd

 * setenv

 * unsetenv

 * env

 * exit

* History

 * history n

 * history -c

 * ^string^string^

 * !string

 * !n

 * !! and !-1

 * CTRL+R (reverse-i-search)

 * :arrow_up: UP or :arrow_down: DOWN

* Copy and Paste

 * CTRL-W - Copy what is currently in front of the cursor.

 * CTRL-G - Copy the entire line.

 * CTRL-K - Cut or delete what is currently in front of the cursor.

 * CTRL-X - Cut or delete the entire line.

 * CTRL-V - Paste the last thing you deleted (using CTRL-K, CTRL-W, CTRL-G or CTRL-X ).

* Auto complete

* unset

* export

* line edition

* the “;” command line separator

* pipes “|”

* redirections “<”, “>”, “<<” & “>>”

* file descriptor aggregation (e.g. ``2>&-`` & ``1>&2``)

* Go directly to the beginning or the end of a line by pressing home and end.

* Move directly by word towards the left or the right using ctrl+LEFT and ctrl+RIGHT.

* Simple logical operators (&& and ||)

* CTRL+T for swapping characters.

* CTRL+P get previous history.

* CTRL+H delete character from cmd

* ls alias (``l`` || ``ll``)
