Description:

The implementation of a simple shell. The shell is an interactive interface that allows users to execute other commands and utilities in Linux and other UNIX-based operating systems. Shells use either a command-line interface or graphical user interface, depending on a computer's role and particular operation.

Example:

 ubuntu@ubuntu$ ./hsh     
 $ pwd
 /home/ubuntu/simple_shell
 $ /bin/pwd
 /home/ubuntu/simple_shell
 $ ls -la
 -rw-rw-r-- 1 vagrant vagrant  bytes <date> builtins.c
 -rw-rw-r-- 1 vagrant vagrant   bytes <date> shell.h

Builtins commands:

 exit: exits a shell
 
 env: show/displays environment variables

Special Features:

 Ctrl + C: To prevent the killing of the simple-shell
 
 Ctrl + D: exit the simple-shell
