read [-options] [variable…] read val

Options

Option	Description
-a array	Assign the input to array, starting with index zero.
-d delimiter	The first character in the string delimiter is used to
	indicate the end of input, rather than a newline character.
-e	Use Readline to handle input. This permits input editing
	in the same manner as the command line.
-i string	Use string as default reply if the user simply presses.
	Requires the -e option.
-n num	Read num characters of input, rather than an entire line.
-p prompt	Display a prompt for input using the string prompt.
-r	Raw mode. Do not interpret backslash characters as escapes.
-s	Silent mode. Do not echo characters to the display as they
	are typed. This is useful when inputting passwords.
-t seconds	Timeout. Terminate input after seconds. Returns a
	non-zero exit status in case of timeout.
-u fd	Use input from the file descriptor fd, rather than
	standard input.
