Features currently present

The shell allows executing external programs if they are found in any of the paths specified by the $PATH variable. 
Variables from within the shell can be passed to external programs by passing the $VARNAME to the program.

Example:
echo $VARNAME
mkdir $DIR_NAME
(and so on)

Also instead of running an interactive shell you can also run a script by calling the shell binary with the path of the script as an argument.
