To display all lines with a character string satisfying a search criterion,
use      :g/<string>/p      (That says global search for string and print.)
If you want to list the lines with line numbers, use "nu" in place of "p".

To delete all lines with a character string satisfying a search criterion,
use      :g/<string>/d      (That says global search for string and delete.)
