Yes. set and shift are so called 'special builtins', and show different behavior on errors, as documented here: http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_14 http://www.opengroup.org/onlinepubs/009695399/idx/sbi.html http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_08_01 So dash is right, it should exit an interactive shell on, e.g., the 'set -o pipefail' error.
