* ash: fail if 'shift' operand is out of rangeIngo van Lil2018-02-141-1/+1
| | | | | | | | | | | | | | | | If the numeric argument passed to ash's 'shift' built-in is greater than '$#' the command performs no operation and exits successfully. It should return a non-zero exit code instead: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#shift This is consistent with bash and hush. function old new delta shiftcmd 122 120 -2 Signed-off-by: Ingo van Lil <inguin@gmx.de> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | Upstream commit: Date: Thu, 30 Oct 2014 11:53:35 +0800 [PARSER] Catch variable length expansions on non-existant specials Currently we only check special variable names that follow directly after $ or ${. So errors such as ${#&} are not caught. This patch fixes that by moving the is_special check to just before we print out the special variable name.
