NAME read - Read a line from the standard input and split it into fields. SYNOPSIS read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...] DESCRIPTION Read a line from the standard input and split it into fields. Reads a single line from the standard input, or from file descriptor FD if the -u option is supplied. The line is split into fields as with word splitting, and the first word is assigned to the first NAME, the second word to the second NAME, and so on, with any leftover words assigned to the last NAME. Only the characters found in $IFS are recognized as word delimiters. If no NAMEs are supplied, the line read is stored in the REPLY variable. Options: -a array	assign the words read to sequential indices of the array	variable ARRAY, starting at zero -d delim	continue until the first character of DELIM is read, rather	than newline -e	use Readline to obtain the line -i text	use TEXT as the initial text for Readline -n nchars	return after reading NCHARS characters rather than waiting	for a newline, but honor a delimiter if fewer than	NCHARS characters are read before the delimiter -N nchars	return only after reading exactly NCHARS characters, unless	EOF is encountered or read times out, ignoring any	delimiter -p prompt	output the string PROMPT without a trailing newline before	attempting to read -r	do not allow backslashes to escape any characters -s	do not echo input coming from a terminal -t timeout	time out and return failure if a complete line of	input is not read within TIMEOUT seconds. The value of the	TMOUT variable is the default timeout. TIMEOUT may be a	fractional number. If TIMEOUT is 0, read returns	immediately, without trying to read any data, returning	success only if input is available on the specified	file descriptor. The exit status is greater than 128	if the timeout is exceeded -u fd	read from file descriptor FD instead of the standard input Exit Status: The return code is zero, unless end-of-file is encountered, read times out (in which case it's greater than 128), a variable assignment error occurs, or an invalid file descriptor is supplied as the argument to -u.
