  Oracle Tips by Burleson

The read statement

The read command is used to accept input from standard input (keyboard) and store it into variables.

One line is read from the standard input and the first word is assigned to the first name, the second word to the second name, and so on, with leftover words assigned to the last name. If there are fewer words read from the input stream than names, the remaining names are assigned empty values.

You can use the p option to specify a prompt to be displayed to the user. The prompt can be used to request that the user enter specific information.

Using read to accept input from the keyboard

$ read name1 name2

Terry Clark

$ echo $name2

Clark

$ echo "Name1: $name1 Name2: $name2"

Name1: Terry Name2: Clark

$ read fullname

Terry L. Clark

$ echo $fullname

Terry L. Clark

$ read -p "Enter your name please: " fullname

Enter your name please: Terry Clark

$ echo $fullname

Terry Clark
