thanks john,
your idea looks quite interesting, though it ends when the filename has
more than one character.
say I have
/opt/too_many_files/secret
/opt/too_many_files/top_secret
/opt/too_many_files/confidential
/opt/too_many_files/public
and don't want to copy top_secret, your idea does not work:
% ls /opt/too_many_files/*[^top_secret]
but digging through the ls manpage I found a solution:
% ls --ignore="top_secret" /opt/too_many_files
