      Is there a command similar to :%s that would delete lines?
      For example, replace all lines containing test to nottest:
      :%s/test/nottest/c
       Instead, is there some way to delete all lines containing test, with confirmation?
      :%(something else)/test/c

      Thanks,
      Ven

        Not sure about the confirmation step. This kind of things works for
        the deleting of lines matching a pattern "test":

        :%g/test/d

          If you do need confirmation, you can do

          :%s/.*test.*\n//\c

          If you don't need confirmation, Chris gave the standard solution,
          except that the "%" is optional since :g defaults to the whole file.

          For the record, the :g command can be inverted to delete every line
          that *doesn't* match "test" by using

          :v/test/d

          -tim
