It turns out that
$ top
prints trailing blanks all the way to the right edge of the screen.

The problem is gone in -b batch mode, but in interactive mode,
especially from remote systems, all those trailing blanks double the size
of traffic, all for no good.
It's as if one needs sed 's/ \+$//' to clean them up.


Hi Dan,

You may have your top configured such that trailing spaces exist but 
others may not.  The phenomenon you cite only occurs when a variable 
length field is displayed as the last field.


Besides, those trailing spaces are output only the first time a line is 
printed or when the line changes.  So you need not be concerned with 
overhead the doesn't exist.


Regards,
Jim
