See also: $ POSIXLY_CORRECT=1 bash -c 'set +o posix; set +o' | grep posix set +o posix $ POSIXLY_CORRECT=1 bash +o posix -c 'set +o' | grep posix set -o posix (not a regression, already in 4.3) I'd expect explicit command line options to take precedence over the environment. Another oddity: $ env SHELLOPTS= bash -o posix -c : $ env SHELLOPTS= bash +o posix -c : bash: SHELLOPTS: readonly variable -- Stephane
