I was intrigued by Michael Hammel's example of a script that
highlights and blinks output (from  <5276@dell.dell.com>),
enough to try to get it to work, and guess what.  Michael
has Dell (Sys5?), so somebody else may need to take a whack 
at this for me (I'm running on a Sun). (It's a 3/50, "running"
is a relative term.)

(I don't code with sh at all, forgive me if this is
all obvious to everyone -- this is c.u.??, right?)

Some fixes were obvious, to make it work more generally, i.e., 
on a Sun, like using the Sys5 echo.  =^}

... But the script still doesn't quite work.  The Sun version of date 
doesn't include the '%B' format; what is that supposed to be generate??? 
For that matter, how are you supposed to get the full 4-char year??

Note that when I run this, I get a highlighted year, but no
blinking date... ?

#obviously wrong: fix me please!

cat $tmp2
rm $tmp $tmp2

(Also, scripts shouldn't try to write files into the working directory,
with all the read-only file-systems one is likely to be working in =-}
