Duplicating File Descriptors

-more digits, the file descriptor denoted by `n' is made to be a copy of
+more digits, the file descriptor denoted by N is made to be a copy of
that file descriptor. If the digits in WORD do not specify a file
descriptor open for input, a redirection error occurs. If WORD

+Moving File Descriptors

`read'
- read [-ers] [-a ANAME] [-p PROMPT] [-t TIMEOUT] [-n NCHARS] [-d DELIM] [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 `REPLY'. The return code is
- zero, unless end-of-file is encountered or `read' times out.

+ One line is read from the standard input, or from the file
