24$FUNCTION read_builtin-
25$SHORT_DOC read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...]-
26Read a line from the standard input and split it into fields.-
27-
28Reads a single line from the standard input, or from file descriptor FD-
29if the -u option is supplied. The line is split into fields as with word-
30splitting, and the first word is assigned to the first NAME, the second-
31word to the second NAME, and so on, with any leftover words assigned to-
32the last NAME. Only the characters found in $IFS are recognized as word-
33delimiters.-
34-
35If no NAMEs are supplied, the line read is stored in the REPLY variable.-
36-
37Options:-
38 -a array assign the words read to sequential indices of the array-
39 variable ARRAY, starting at zero-
40 -d delim continue until the first character of DELIM is read, rather-
41 than newline-
42 -e use Readline to obtain the line-
43 -i text use TEXT as the initial text for Readline-
44 -n nchars return after reading NCHARS characters rather than waiting-
45 for a newline, but honor a delimiter if fewer than-
46 NCHARS characters are read before the delimiter-
47 -N nchars return only after reading exactly NCHARS characters, unless-
48 EOF is encountered or read times out, ignoring any-
49 delimiter-
50 -p prompt output the string PROMPT without a trailing newline before-
51 attempting to read-
52 -r do not allow backslashes to escape any characters-
53 -s do not echo input coming from a terminal-
54 -t timeout time out and return failure if a complete line of-
55 input is not read within TIMEOUT seconds. The value of the-
56 TMOUT variable is the default timeout. TIMEOUT may be a-
57 fractional number. If TIMEOUT is 0, read returns-
58 immediately, without trying to read any data, returning-
59 success only if input is available on the specified-
60 file descriptor. The exit status is greater than 128-
61 if the timeout is exceeded-
62 -u fd read from file descriptor FD instead of the standard input-
63-
64Exit Status:-
65The return code is zero, unless end-of-file is encountered, read times out-
66(in which case it's greater than 128), a variable assignment error occurs,-
67or an invalid file descriptor is supplied as the argument to -u.-
