The man page for sh on a GNU/Linux system is for bash. As I mentioned
there are a LOT of features of bash that aren't supported by POSIX sh
(and hence ash).
The best thing to do is register with The Open Group, then you can read
their documentation online.
I personally always write all my programs and scripts to the POSIX
specification, for maximum portability. If there's some advanced
feature I need that isn't provided by POSIX, only then will I carefully
venture into Linux-specific areas.
