Re: Unifying BSD sed -E and GNU sed -r options?

[Dan Kegel]

Right, but for now, I have to check platform before using it, e.g.

    case $_os in
    osx*) xregx=-E;;
    *) xregx=-r;;
    esac
    ... sed $xregx ...

I'd like it if either -r or -E worked on both gnu and bsd sed.
So this is a standardization enhancement request,
and it's possible bsd is the one that should change.
I have not yet done a search to see which of the two options
is used more in practice.
