Yes, I recommend dash as your /bin/sh if you're using a
Debian-based system ("Debian Almquist shell") such as Ubuntu.
Also, the Debian "devscripts" package has a tool called
"checkbashisms" which I have also found very useful.
Maybe ksh(93) or posh could be good, too, but it's been a
while...
I also rely on checking the manpages-posix and manpages-posix-dev
in the "non-free" section of Debian ("multiverse" in Ubuntu?)
