33/46 61% + 10 Page 33 read • To get input from the keyboard, you use the read command. The read command takes input from the keyboard and assigns it to a variable. Here is an example: #!/bin/bash echo -n "Enter some text > ". read text echo "You entered: $text" . As you can see, we displayed a prompt on line 3. Note that "-n" given to the echo command causes it to keep the cursor on the same line; i.e., it does not output a linefeed at the end of the prompt.

This is useful when you are asking the user to type in a password or other confidential information.
