Fine, although not the fastest solution. Slightly better
is:
$abc = (split /\s+/, $_, 9)[8];
which stops it trying to split after the eighth field.

No, don't bother. You really want a regex for this
situation:
$abc = /([^\S]*)$/;
if you really, really wanted to use split:
$abc = (split /\s+/)[-1];
