Read a line from standard input
SYNTAX read [-ers] [-a aname] [-p prompt] [-t timeout] [-n nchars] [-d delim] [name...] OPTIONS -a aname The words are assigned to sequential indices of the array variable aname, starting at 0. All elements are removed from aname before the assignment. Other name arguments are ignored. -d delim The first character of delim is used to terminate the input line, rather than newline. -e If the standard input is coming from a terminal, Readline is used to obtain the line. -n nchars read returns after reading nchars characters rather than waiting for a complete line of input. -p prompt Display prompt, without a trailing newline, before attempting to read any input. The prompt is displayed only if input is coming from a terminal. -r If this option is given, backslash does not act as an escape character. The backslash is considered to be part of the line. In particular, a backslash-newline pair may not be used as a line continuation. -s Silent mode. If input is coming from a terminal, characters are not echoed. -t timeout Cause read to time out and return failure if a complete line of input is not read within timeout seconds. This option has no effect if read is not reading input from the terminal or a pipe.
This is a BASH shell builtin.
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 and their intervening separators assigned to the last name.
If there are fewer words read from the standard input than names, the remaining names are assigned empty values.
The characters in the value of the
IFS variable are used to split
the line into words.
The backslash character `\' may be used to remove any special meaning for the next character read and for line continuation.
If no names are supplied, the line read is assigned to the variable
The return code is zero, unless end-of-file is encountered or
