don't think you can do it with REs, here's grep command you can use on
command line:
ls | grep -v '^index.html$'
if you're doing it in some script/program you will have to implement
it that way yourself - example in perl:
#!/usr/bin/perl
#
use strict;
my($pattern) = 'index.html';
my(@list) = glob('*');
print "file list:\n";
foreach(@list) { print "\t$_\n"; }
@list = grep { ! /$pattern/ } @list;
print "file list with no [$pattern]\n";
foreach(@list) { print "\t$_\n"; }
__END__
in other words you do not specify the negation in RE but instead in
context where RE is used.
