in thread [Good news] here docs portability!

As much as I like being right by accident, don't even old Bourne shells honor -e? In my original comment, I was thinking of c shells, which do not.

But instead of relying on the system's /bin/echo, which who knows, might be broken in rusty old systems, why not use Perl for this command (since we know the user has it...)

    Broken? Per POSIX, -e is not a special flag, and should be output. With the XSI extensions, you are supposed to get \r -> CR whether you want it or not. Without XSI, the output when there are backslashes is undefined.

    So perl is the way to go.
