Data can be stored and removed within a variable using an '''equal sign''' (no spaces on either side of equal sign).<br><br>The '''read''' command can be used to prompt the user to enter data into a variable. The '''readonly''' command will prevent the current value of the variable for the remainder of the execution of a shell script.<br><br>
