Dr. Chip's LogiPat plugin[1] makes quick work of generating such patterns. I did :echo LogiPat('"arch"&!"sparc"') and it gives me the pattern \%(.*arch.*\&^\%(\%(sparc\)\@!.\)*$\) which I can then use in a :g/pattern/d command: :g/\%(.*arch.*\&^\%(\%(sparc\)\@!.\)*$\)/d [1] http://www.vim.org/scripts/script.php?script_id=1290

Hi Tim,
Wow thank you. without the plugin it looks too complex..
Maybe vim developers should consider adding pattern combination function with simpler syntax..
