While checking for more bashisms affecting the dash as /bin/sh RG I noticed that 'export -n' is a bashism. Trivia: ---- $ cat exportn #!/bin/sh FOO=bar export FOO $SHELL -c 'echo $FOO' export -n FOO $SHELL -c 'echo $FOO' $ bash ./exportn bar $ zsh ./exportn bar ./exportn:6: bad option: -n bar $ ksh ./exportn bar export: -n: unknown option Usage: export [-p] [name[=value]...] $ posh ./exportn bar export: invalid option -- n bar $ pdksh ./exportn bar ./exportn[6]: export: -n: unknown option $ dash ./exportn bar export: 6: Illegal option -n ---- export -f also seems to be a bashism (only zsh doesn't scream when export -f is called).
