"The read command is designed to read and then use in the script input from the user. The input that is provided by the user is stored as a variable. This is a builtin variable that will store one line of input from the user in one or more variables. The read command is valuable as it is a major way to input information into a shell script. Lines are read into the script with standard input and split via the $IFS variable. This stands for internal field separator. The first word is assigned the first variable, the second word the second variable, etc.
