Hi,
Can someone please confirm whether /bin/sh is still POSIX compliant on
10.12.latest (i.e. `/bin/sh --version` shows it's actually bash), please?
thanks,
René
from `man bash':
"If bash is invoked with the name sh, it tries to mimic the startup
behavior of historical versions of sh
as closely as possible, while conforming to the POSIX standard as
well."
whatever "tries" means exactly ... ;-). there is another hint somewhere
else at "brace expansion" handling. my reading of that is that you would
have to call `sh +B' or do `set +B' within your script to get _strict_
`sh' compliance. -- but better read the manpage yourself ;-)
