1. Write a BASH shell script that acts as a DOS command interpreter (the user enters the DOS command and the script executes the corresponding Linux command). The script should loop continuously until the user enters the QUIT command Prior to accepting a command, display a prompt containing your first name and the greater than symbol (>) Example prompt: linux> The DOS command, and any arguments, should be stored in variables $command - the DOS command (required) Sarg1 - the first argument (optional) Sarg2 - the second argument (optional) Note: Only some DOS/Linux commands will require one or both argument variables. The script should use case statements to select the appropriate Linux command If an unknown DOS command is entered, display the error message, Command Not Found! 2. Refer to the table below for a list of DoS commands and their Linux counterparts (COMMAND (ARG 1] [ARG 2]) DOS Command* CHDIR [target directory] Linux Command cd [target directory] CLS clear COPY [source file] [destination file] CREATEDIR (directory name] CREATEFILE [file name] DELETE [file name] DIR [file name | directory name | wildcard] Is [file name directory name | wildcard] MOVE (source] [destination] PRINT [message to print] QUIT RENAME [old name] [new name] TYPE [file name] cp [source file] [destination file] mkdir [directory name] touch [file name] rm [file name] mv [source] [destination] echo [message to print] N/A mv [old name] [new name] cat [file name] Assume DOS commands are case-insensitive (i.e., DIR is the same as dir).
