If the shell script is readable and executable then to execute it just type the name of the shell script file. Otherwise, you can explicity call a shell interpreter to run the file as a shell script, i.e., ksh myfile

The 'exit' command allows you to stop a running shell script at any point and to return a "status" value back to whomever called the shell script. This is a very common practice with shell scripts; sometimes you want to stop the script before it gets to the end of the shell script (for various logic reasons). The 'exit' command also allows you to give a status that any other calling process can use to determine if the shell script ended successfully or not.
It depends on the script language you are using. In the Korn shell, you can say: echo -n "Enter the first number: " read first echo -n "Enter the second number: " read second let third=$first+$second echo The answer is $third
