[vox-tech] serendipity with vim

[Ken Bloom]

In sed, one can delete every line matching a pattern with the command
"/pattern/d". In vi, using the analagous command ":/pattern/d" only deletes  
the first line that matches the pattern. How do you delete all the lines  
that match the pattern? ":g/pattern/d"   (:g[lobal] lets you apply an ex  
command to every line matching a pattern)
