Z:gnu-bash--30bd50-Read a line from the standard/en

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 in an interactive shell -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.
