You mean with the same amount of whitespace as before? None of the
solutions I've seen does that.
Perhaps this is one way:
$_ = 'This is the string I want AND THIS IS BOLLOCKS';
{
my @end;
push @end, $+[0] while/\S+/g;
splice @end, -4;
substr($_, pop @end) = "";
}
print;
No, it's not really *that* elegant. But it does put two spaces between
"is" and "the", just as in the original.
