Hello,

zeisberger@io:~$ VN=$(nonexistentcmd) || echo lala bash: nonexistentcmd: command not found lala

uzeisberger@io:~$ VN=$(nonexistentcmd | sed 's/-/./g') || echo lala bash: nonexistentcmd: command not found

The reason is (from bash(1)):

	The return status of a pipeline is the exit status of the last
	command, unless the pipefail option is enabled.

and the sed command is fine.

pipefail is not portable, i.e. Solaris' sh doesn't support it.

I'd suggest:

	if VN=$(git-describe --abbrev=4 HEAD 2>/dev/null); then
		VN=$(echo "$VN" | sed 's/-/./g');
	else
		VN=$(cat version) || VN="$DEF_VER";
	fi

This works with Solaris' sh and bash.

Best regards Uwe
