Would something like this do?

perl -e'@cols =qw (need1 dont1 need2 dont2 need3); for (@cols) { push(
+@req,$_) unless /dont.*/;} print join (",",@req),$/;'
__END__
need1,need2,need3

You mentiioned regex so the above should help you. However if the names you want to choose are sent as input then you might want to construct a hash from the list and then drop the ones that should be excluded by checking the hash

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
