Okay had such a great response before and learned lots but how about
another question?
have some strings such as:
blahblah /* comment */
blahblah
blah blah
blah blah blah /* comment etc */
And i want just the blahblah bit, not any comments if there are any.
Any ideas on how to do this using a single regex would be most welcome,
I know I'm pushing my luck 
Thanks
Bob

You're best off doing this the other way around (untested):
str.gsub(/\/\*.*?\*\//m, '')
That way you're stripping the comments out of the string, rather than trying to find bits of the string that happen not to be in comments. I'm not sure it's possible to simply do the latter, but I'm sure someone will be along in a few moments to prove me wrong

Script starts
#!/bin/sh
ruby -wnle 'puts %r{^(.*?)(\s*/\*.*\*/\s*)?$}.match($_).captures[0]' <<EOF
Mary /* a girl */
had a
little /* but no less valuable */
lamb
EOF
<<< Script ends
Output starts
Mary
had a
little
lamb
<<< Output ends

EOS
puts str.gsub(/\/\*.*/,'')
This won't work for multi-line comments unfortunately.

for multi-line comments, its the same thing
just parse it a second time but replace
/*
and
*/
with
=begin
and
=end
