read [ -rszpqAclneE ] [ -t [ num ] ] [ -k [ num ] ] [ -d delim ]
     [ -u n ] [ [name][?prompt] ] [ name ...  ]
       Read  one  line and break it into fields using the characters in
       $IFS as separators, except as noted below.  The first  field  is
       assigned to the first name, the second field to the second name,
       etc.,  with  leftover fields assigned to the last name.  If name
       is omitted then REPLY is used for scalars and reply for arrays.

       -r     Raw mode: a `\' at the end of a  line  does  not  signify
              line continuation and backslashes in the line don't quote
              the following character and are not removed.

       -s     Don't echo back characters if reading from the terminal.

       -q     Read only one character from the terminal and set name to
              `y'  if  this  character was `y' or `Y' and to `n' other-
              wise.  With this flag set the return status is zero  only
              if the character was `y' or `Y'.  This option may be used
              with  a  timeout  (see -t); if the read times out, or en-
              counters end of file, status 2  is  returned.   Input  is
              read from the terminal unless one of -u or -p is present.
              This option may also be used within zle widgets.

       -k [ num ]
              Read  only  one (or num) characters.  All are assigned to
              the first name, without word splitting.  This flag is ig-
              nored when -q is present.  Input is read from the  termi-
              nal  unless  one of -u or -p is present.  This option may
              also be used within zle widgets.

              Note that despite the mnemonic  `key'  this  option  does
              read full characters, which may consist of multiple bytes
              if the option MULTIBYTE is set.

       -z     Read one entry from the editor buffer stack and assign it
              to  the  first  name,  without  word  splitting.  Text is
              pushed onto the stack with `print -z' or  with  push-line
              from  the  line editor (see zshzle(1)).  This flag is ig-
              nored when the -k or -q flags are present.

       -e
       -E     The input read is printed (echoed) to the  standard  out-
              put.  If the -e flag is used, no input is assigned to the
              parameters.

       -A     The  first  name is taken as the name of an array and all
              words are assigned to it.

       -c
       -l     These flags are allowed only if called inside a  function
              used  for  completion (specified with the -K flag to com-
              pctl).  If the -c flag is given, the words of the current
              command are read. If the -l flag is given, the whole line
              is assigned as a scalar.  If both flags are  present,  -l
              is used and -c is ignored.

       -n     Together with -c, the number of the word the cursor is on
              is  read.  With -l, the index of the character the cursor
              is on is read.  Note that the command name is word number
              1, not word 0, and that when the cursor is at the end  of
              the  line,  its character index is the length of the line
              plus one.

       -u n   Input is read from file descriptor n.

       -p     Input is read from the coprocess.

       -d delim
              Input is terminated by the first character of  delim  in-
              stead of by newline.

       -t [ num ]
              Test if input is available before attempting to read.  If
              num  is  present,  it must begin with a digit and will be
              evaluated to give a number of seconds,  which  may  be  a
              floating point number; in this case the read times out if
              input  is  not available within this time.  If num is not
              present, it is taken to be zero, so that read returns im-
              mediately if no input  is  available.   If  no  input  is
              available, return status 1 and do not set any variables.

              This option is not available when reading from the editor
              buffer  with  -z, when called from within completion with
              -c or -l, with -q which clears  the  input  queue  before
              reading,  or  within zle where other mechanisms should be
              used to test for input.

              Note that read does not attempt to alter the  input  pro-
              cessing  mode.   The  default mode is canonical input, in
              which an entire line is read at a time, so usually  `read
              -t'  will not read anything until an entire line has been
              typed.  However, when reading from the terminal  with  -k
              input  is processed one key at a time; in this case, only
              availability of the first character is  tested,  so  that
              e.g. `read -t -k 2' can still block on the second charac-
              ter.   Use  two  instances of `read -t -k' if this is not
              what is wanted.

       If the first argument contains a `?', the remainder of this word
       is used as a prompt on standard error when the shell is interac-
       tive.

       The value (exit status) of read is 1 when an end-of-file is  en-
       countered,  or  when  -c or -l is present and the command is not
       called from a compctl function, or as described for -q.   Other-
       wise the value is 0.

       The  behavior  of some combinations of the -k, -p, -q, -u and -z
       flags is undefined.  Presently -q cancels  all  the  others,  -p
       cancels  -u, -k cancels -z, and otherwise -z cancels both -p and
       -u.

       The -c or -l flags cancel any and all of -kpquz.
