It looks like you want to remove lines that (optionally) contain spaces in addition to uppercase. This one-liner will do the trick:

perl -ne 'print unless /^[A-Z\s]+$/' <in.txt >out.txt

Of course if you are including this in a larger Perl program, you can just nab the regex out of that, and use it in a loop construct of some kind. For example:

while (<>) { print if !/^[A-Z\s]+$/ }
