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) o The script should loop continuously until the user enters the QUIT command o Prior to accepting a command, display a prompt containing your first name and the greater than symbol (>) Example prompt: linux> o The DOS command, and any arguments, should be stored in variables Scommand - the DOS command (required) $arg1 - the first argument (optional) $arg2 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! o 2. Refer to the table below for a list of DOS commands and their Linux counterparts (COMMAND [ARG 1] [ARG 2]) DOS Command Linux Command cd [target directory] clear cp [source file] [destination file] mkdir [directory name] touch [file name] rm [file name] CHDIR [target directory] CLS 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] Assume DOS commands are case-insensitive (i.e., DIR is the same as dir). mv [source] [destination] echo [message to print] N/A mv [old name] [new name] cat [file name]
