Vi question

Mike Boswell_1 — Fri, 11 Dec 2009 15:22:27 GMT

This command will print out all lines from catalina.out that match HOME or ERROR or WARN. awk '/HOME|ERROR|WARN/{print $0}' catalina.out

How could I do the same within vi? IE the following :%g!/ERROR/d will delete all lines that do not match ERROR but I would like WARN and HOME to remain as well.

Thanks,
Mike

Is it a requisite to do it with vi? isn't it enough to redirect the ouput of awk to another file?
