Hello!

In this project, we have developed a command-line interpreter (or shell) which supports environment variables and history of executed commands. Our shell is capable of:

• Recognizing lines of the form $<VAR>=<value>
• Recognizing lines of the form <command> <arg0> <arg1> … <argN>, where <command> is a name of built-in command.

The following built-in commands are supported:

• exit, the shell terminates on this Command
• log, the shell prints history of executed commands with time and return code
• print, the shell prints argument given to this Command
• theme, the shell changes the color of and output

To compile this program, run: "make"

To run the file in the standard interactive mode, type: ./cshell

To run the file in script mode (using the file "script.txt"), type: ./cshell script.txt

• script.txt can be modified to fit your needs
