# $OpenBSD: read.t,v 1.2 2022/10/16 12:34:13 kn Exp $
#
# To test:
# POSIX:
# - if no -r, \ is escape character
# - \newline disappear
# - \<IFS> -> don't break here
# - \<anything-else> -> <anything-else>
# - if -r, backslash is not special
# - if stdin is tty and shell interactive
# - prompt for continuation if \newline (prompt to stderr)
# - a here-document isn't terminated after newline ????
# - remaining vars set to empty string (not null)
# - check field splitting
# - left over fields and their separators assigned to last var
# - exit status is normally 0
# - exit status is > 0 on eof
# - exit status > 0 on error
# - signals interrupt reads
# extra:
# - can't change read-only variables
# - error if var name bogus
# - set -o allexport effects read
# ksh:
# x check default variable: REPLY
# - check -p, -s, -u options
# - check var?prompt stuff
# - "echo a b | read x y" sets x,y in parent shell (at&t)
